The experiment was performed on an agricultural field contaminated by the Non-Ferrous-Metal Works (MFMW) near Plovdiv, Bulgaria. The experimental plots were situated at different distances (0.1, 0.5, 2.0, and 15 km) from the source of pollution. The contents of heavy metals in plant materials (roots, stems, leaves, seeds) were determined. The quality of safflower oils (heavy metals and fatty acid composition) was also determined. The quantitative measurements were carried out with inductively-coupled plasma (ICP). Safflower is a plant that is tolerant to heavy metals and can be referred to the hyperaccumulators of lead and cadmium and the accumulators of zinc. The plant can be successfully used in the phytoremediation of heavy metal contaminated soils. The processing of safflower seeds into oil and the use of the obtained oil will greatly reduce the cost of phytoremediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulation" title=" accumulation"> accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=safflower" title=" safflower"> safflower</a>, <a href="https://publications.waset.org/abstracts/search?q=polluted%20soils" title=" polluted soils"> polluted soils</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title=" phytoremediation"> phytoremediation</a> </p> <a href="https://publications.waset.org/abstracts/49641/accumulation-of-heavy-metals-in-safflower-carthamus-tinctorius-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49641.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4311</span> Phytoremediation: An Ecological Solution to Heavy-Metal-Polluted Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasreen%20Jeelani">Nasreen Jeelani</a>, <a href="https://publications.waset.org/abstracts/search?q=Huining%20Shi"> Huining Shi </a>, <a href="https://publications.waset.org/abstracts/search?q=Di%20An">Di An</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Xia"> Lu Xia</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuqing%20An"> Shuqing An</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals contamination in aquatic ecosystem is a major environmental problem since its accumulation along the food chain pose public health risk. The concentration of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in soil and plants species collected from different streams of Suoxu River, China was investigated. This aim was to define the level of pollutants in Suoxu River, find which plant species exhibits the greatest accumulation and to evaluate whether these species could be useful for phytoremediation. While total soil Cd, Cr, Cu, Ni, Pb, and Zn concentrations varied, respectively, from 0.09 to 0.23 , 58.6 to 98, 9.72 to 80.5, 15.3 to 41, 15.2 to 27.3 and 35 to 156 (mg-kg-1), those in plants ranged from 0.035 to 0.49, 2.91 to 75.6, 4.79 to 32.4, 1.27 to 16.1, 0.62 to10.2, 18.9 to 84.6 (mg-kg-1), respectively. Based on BCFs and TFs values, most of the studied species have potential for phytostabilization. The plants with most effective in the accumulation of metals in shoots are Phragmatis australis (TF=2.29) and Iris tectorum (TF =2.07) for Pb. While Chenopodium album, (BCF =3.55), Ranunculus sceleratus, (BCF= 3.0), Polygonum hydropiper (BCF =2.46) for Cd and Iris tectorum (BCF=2.0) for Cu was suitable for phytostabilization. Among the plant species screened for Cd, Cr, Cu, Ni, Pb and Zn, most of the species were efficient to take up more than one heavy metal in roots. Our study showed that the native plant species growing on contaminated sites may have the potential uses for phytoremediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=huaihe%20river%20catchments" title=" huaihe river catchments"> huaihe river catchments</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=plants" title=" plants"> plants</a> </p> <a href="https://publications.waset.org/abstracts/30189/phytoremediation-an-ecological-solution-to-heavy-metal-polluted-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4310</span> Efficacy of Pisum sativum and Arbuscular Mycorrhizal Symbiosis for Phytoextraction of Heavy Metalloids from Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ritu%20Chaturvedi">Ritu Chaturvedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Paul"> Manoj Paul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A pot experiment was conducted to investigate the effect of Arbuscular mycorrhizal fungus (AMF) on metal(loid) uptake and accumulation efficiency of Pisum sativum along with physiological and biochemical response. Plants were grown in soil spiked with 50 and 100 mg kg-1 Pb, 25 and 50 mg kg-1 Cd, 50 and 100 mg kg-1 As and a combination of all three metal(loid)s. A parallel set was maintained and inoculated with arbuscular mycorrhizal fungus for comparison. After 60 days, plants were harvested and analysed for metal(loid) content. A steady increase in metal(loid) accumulation was observed on increment of metal(loid) dose and also on AMF inoculation. Plant height, biomass, chlorophyll, carotenoid and carbohydrate content reduced upon metal(loid) exposure. Increase in enzymatic (CAT, SOD and APX) and nonenzymatic (Proline) defence proteins was observed on metal(loid) exposure. AMF inoculation leads to an increase in plant height, biomass, chlorophyll, carotenoids, carbohydrate and enzymatic defence proteins (p≤0.001) under study; whereas proline content was reduced. Considering the accumulation efficiency and adaptive response of plants and alleviation of stress by AMF, this symbiosis can be applied for on-site remediation of Pb and Cd contaminated soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=mycorrhiza" title=" mycorrhiza"> mycorrhiza</a>, <a href="https://publications.waset.org/abstracts/search?q=pea" title=" pea"> pea</a>, <a href="https://publications.waset.org/abstracts/search?q=phyroremediation" title=" phyroremediation"> phyroremediation</a> </p> <a href="https://publications.waset.org/abstracts/83049/efficacy-of-pisum-sativum-and-arbuscular-mycorrhizal-symbiosis-for-phytoextraction-of-heavy-metalloids-from-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83049.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4309</span> Heavy Metal Concentration in Orchard Area, Amphawa District, Samut Songkram Province, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sisuwan%20Kaseamsawat">Sisuwan Kaseamsawat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sivapan%20Choo-In"> Sivapan Choo-In</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study was conducted in May to July 2013 with the aim of determination of heavy metal concentration in orchard area. 60 samples were collected and analyzed for Cadmium (Cd), Copper (Cu), Lead (Pb), and Zinc (Zn) by Atomic Absorption Spectrophotometer (AAS).

In this experiment, factor A was three Bacillus pumilus strains (sequence C-2PMW-8, C-1 SSK-8 and C-1 PWK-7) while soil used for this experiment was collected from Prang Ghar mining site and lettuce seeds were grown in three levels of chromite mining soil (2.27, 4.65 and 7.14 %). For mining soil minimum days to germinate noted in lettuce grown on garden soil inoculated with sequence. Maximum germination percentage noted was for C-1 SSK-8 grown on garden soil, maximum lettuce height for sequence C-2 PWM-8, fresh leaf weight for C-1 PWK-7 inoculated lettuce, dry weight of lettuce leaf for lettuce inoculated with C-1 SSK-8 and C-1 PWK-7 strains, number of leaves per plant for lettuce inoculated with C-1 SSK-8, leaf area for C-2 PMW-8 inoculated lettuce, survival percentage for C-1 SSK-8 treated lettuce and chlorophyll content for C-2 PMW-8. Results related to heavy metals accumulation showed that minimum chromium was in lettuce and in soil for all three sequences, cadmium (Cd) in lettuce and in soil for all three sequences, manganese (Mn) in lettuce and in soil for three sequences, lead (Pb) in lettuce and in soil for three sequences. It can be concluded that chromite mining soil significantly reduced the growth and survival of lettuce, but when lettuce was inoculated with Bacillus.pumilus strains, it enhances growth and survival. Similarly, minimum heavy metal accumulation in plant and soil, regardless of type of Bacillus pumilus used, all three sequences has same mitigating effect on heavy metal in both soil and lettuce. All the three Bacillus pumilus strains ensured reduction in heavy metals content (Mn, Cd, Cr) in lettuce, below the maximum permissible limits of WHO 2011. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacillus%20pumilus" title="bacillus pumilus">bacillus pumilus</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=permissible%20limits" title=" permissible limits"> permissible limits</a>, <a href="https://publications.waset.org/abstracts/search?q=lettuce" title=" lettuce"> lettuce</a>, <a href="https://publications.waset.org/abstracts/search?q=chromite%20mining%20soil" title=" chromite mining soil"> chromite mining soil</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigating%20effect" title=" mitigating effect"> mitigating effect</a> </p> <a href="https://publications.waset.org/abstracts/181677/effect-of-bacillus-pumilus-strains-on-heavy-metal-accumulation-in-lettuce-grown-on-contaminated-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">59</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4307</span> Heavy Metal Pollution in Soils of Yelagirihills,Tamilnadu by EDXRF Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chandrasekaran">Chandrasekaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ravisankar%20N.%20Harikrishnan"> Ravisankar N.

The average concentration of Pb, Cu, Cd, Ni and Zn in roadside soils was determined to be 43.8, 26.5, 0.119, 32.1, 71.3 mg/kg respectively, and all of the heavy metal contents were higher than the background values. Different heavy metal distribution regularity was found in different land use type of roadside soil, there was an obvious peak of heavy concentration at 25m from road edge in the farmland, while in the forest and orchard soil, all heavy metals gradually decreased with the increase of distance from road edge and conformed to the exponential model. Furthermore, the heavy metal contents of heavy metals except Cd were markedly increased compared with those in 1999 and 2007, and the heavy metals concentrations of Shenyang- Dalian Highway were considered medium or low in comparison with those in other cities around the world. The assessment of heavy metal contamination of roadside soils illustrated a common low pollution for all heavy metal and recommended that more attention should be paid to Pb contamination in roadside soils in Shenyang-Dalian Highway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20contamination" title="heavy metal contamination">heavy metal contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=roadside" title=" roadside"> roadside</a>, <a href="https://publications.waset.org/abstracts/search?q=highway" title=" highway"> highway</a>, <a href="https://publications.waset.org/abstracts/search?q=Nemerow%20Pollution%20Index" title=" Nemerow Pollution Index"> Nemerow Pollution Index</a> </p> <a href="https://publications.waset.org/abstracts/12506/assessment-of-heavy-metal-contamination-in-roadside-soils-along-shenyang-dalian-highway-in-liaoning-province-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4305</span> Oncological Consequences of Heavy Metal Deposits in Jos East, Plateau State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasini%20Waida">Jasini Waida</a>, <a href="https://publications.waset.org/abstracts/search?q=Usman%20Rilwan"> Usman Rilwan</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20I.%20Ikpughul"> S.

The results of this study showed that the Geo-Accumulation Index (Igeo) of water for different heavy metals decreased in the order of Cd (0.15) > Cr and As (0.03) > Pb (-0.13) > Ni (-0.6). The soil content for different heavy metals decreased in the order of As and Cd (0.4) > Ni, Cr and Pb (0.2). The edible plants for different heavy metals decreased in the order of Cd (0.512) > As (0.25) > Pb (0.23) > Ni (0.01) > Ni (-0.06). 21% of these points are uncontaminated, except for a few points that are found within the uncontaminated to moderately contaminated level. It is possible to conclude that the area is uncontaminated to moderately contaminated, necessitating regulation. Hence, this study can be used as reference data for regulatory bodies like the Nigerian Nuclear Regulatory Authority (NNRA) and the rest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=plants" title=" plants"> plants</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination%20factor" title=" contamination factor"> contamination factor</a> </p> <a href="https://publications.waset.org/abstracts/164092/oncological-consequences-of-heavy-metal-deposits-in-jos-east-plateau-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4304</span> Removal of Heavy Metals in Wastewater Treatment System of Suan Sunandha Rajabhat University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pantip%20Kayee">Pantip Kayee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuwadee%20Yaponha"> Yuwadee Yaponha</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiranit%20Pongtubthai"> Jiranit Pongtubthai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on the determination of heavy metal concentration in wastewater and the investigation of heavy metal removal of wastewater treatment system of Suan Sunandha Rajabhat University.

Vaseashta </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Lake Sevan basin is situated in the eastern part of the Republic of Armenia (Gegharquniq marz/district). The heavy metal pollution of the some tributaries of Lake Sevan was investigated. Water sampling was performed in August and December, 2014 from the 4 observation sites: 1) Sotq river upstream (about 600 meters upstream from the Sotq gold mine); 2) Sotq river mouth; 3) Masrik river mouth; 4) Dzknaget river mouth. Heavy metal (V, Fe, Ni, Cu, As, Mo, Pb) concentrations in the water samples were determined by the standard methods using an atomic absorption spectrophotometer. The results of the study showed that heavy metal content mainly increased from the upstream of the Sotq river to the mouth of the Masrik river which may have been conditioned by the influence of gold mining activity as the Masrik and its tributary-Sotq rivers passing through the gold mining area were exposed to heavy metal pollution. The observation sites can be ranked by pollution degree as follows: №3> №2> №1> №4. The highest heavy metal pollution degree was observed in the Masrik river mouth which may have been conditioned by the direct impact of gold mining activity and the pressure of its tributary–the Sotq river which flows through the gold mining area. The lowest heavy metal pollution degree was registered in the Dzknaget river mouth which flowing through rural areas wasn’t subject to significant heavy metal pollution. According to the observation sites of the Sotq and Masrik rivers, high positive correlation was mainly observed between the concentrations of the investigated heavy metals (except nickel) which indicated that all the heavy metals except the nickel had the same anthropogenic pollution source which was the activity of the Sotq gold mine. In general, it is possible to state that the activity of the Sotq gold mine in the Lake Sevan basin caused the heavy metal pollution of the Sotq and Masrik rivers which may have posed environmental hazards. Heavy metals are nondegradable substances, and heavy metal pollution of freshwater systems may pose risks to the environment and human health through accumulation in the tissues of aquatic organisms, water-food chain as well as oral ingestion and dermal contact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armenia" title="Armenia">Armenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Lake%20Sevan%20basin" title=" Lake Sevan basin"> Lake Sevan basin</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20mining%20activity" title=" gold mining activity"> gold mining activity</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20ecosystems" title=" river ecosystems"> river ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20pollution" title=" heavy metal pollution"> heavy metal pollution</a> </p> <a href="https://publications.waset.org/abstracts/30069/investigation-of-the-heavy-metal-pollution-of-the-river-ecosystems-in-the-lake-sevan-basin-armenia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">584</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4302</span> Assessment of Proximate Composition and Heavy Metal in Vigna unguculata (White Beans) Sold in Kazaure Market, Jigawa State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdu%20Umar%20Adamu">Abdu Umar Adamu</a>, <a href="https://publications.waset.org/abstracts/search?q=Saidu%20Akun%20Abdullahi"> Saidu Akun Abdullahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Al-Hassan%20Muhammed"> Al-Hassan Muhammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamisu%20Abdu"> Hamisu Abdu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leguminous plants such as beans have been considered as a source of protein in this present work.

The entry of waste into the waters of the Bay of Jakarta has caused pollution. Heavy metal contamination has led to pollution levels and may cause toxicity to organisms that live in the sea, down to the cellular level and may affect the ecological balance. Various ways have been conducted to measure the impact of environmental degradation, such as by measuring the levels of contaminants in the environment, including measuring the accumulation of toxic compounds in the tissues of organisms. Biological responses or biomarkers known as a sensitive indicator but need relevant predictions. In heavy metal pollution monitoring, analysis of aquatic biota is very important from the analysis of the water itself. The content of metals in aquatic biota will usually always be increased from time to time due to the nature of metal bioaccumulation, so the aquatic biota is best used as an indicator of metal pollution in aquatic environments.

The aim of this research was to assess the heavy metal bioaccumulation in edible parts of common carp (Cyprinus carpio) in Lake Koka and the health risks associated with the dietary intake of the fish. Three sampling sites were selected randomly for primary data collection. Physicochemical parameters (pH, Total Dissolved Solids, Dissolved Oxygen and Electrical Conductivity) were measured in-situ. Four heavy metals (Cd, Cr, Pb, and Zn) in water and bio-accumulation in the edible parts of the fish were analyzed with flame atomic absorption spectrometry. The mean values of TDS, EC, DO and pH of the lake water were 458.1 mg/L, 905.7 µ s/cm, 7.36 mg/L, and 7.9, respectively. The mean concentrations of Zn, Cr, and Cd in the edible part of fish were also 0.18 mg/kg, ND-0.24 mg/kg, and ND-0.03 mg/kg, respectively. Pb was, however, not identified. The amount of Cr in the examined fish muscle was above the level set by FAO, and the accumulation of the metals showed marked differences between sampling sites (p<0.05). The concentrations of Cd, Pb and were below the maximum permissible limit. The results also indicated that Cr has a high transfer factor value and Zn has the lowest. The carcinogenic hazard ratio values were below the threshold value (<1) for the edible parts of fish. The estimated weekly intake of heavy metals from fish muscles ranked as Cr>Zn>Cd, but the values were lower than the Reference Dose limit for metals. The carcinogenic risk values indicated a low health risk due to the intake of individual metals from fish. Furthermore, the hazard index of the edible part of fish was less than unity. Generally, the water quality is not a risk for the survival and reproduction of fish, and the heavy metal contents in the edible parts of fish exhibited low carcinogenic risk through the food chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-accumulation" title="bio-accumulation">bio-accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=cyprinus%20carpio" title=" cyprinus carpio"> cyprinus carpio</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20index" title=" hazard index"> hazard index</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=Lake%20Koka" title=" Lake Koka"> Lake Koka</a> </p> <a href="https://publications.waset.org/abstracts/158442/consumer-health-risk-assessment-from-some-heavy-metal-bioaccumulation-in-common-carp-cyprinus-carpio-from-lake-koka-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158442.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4298</span> Spatial Variability of Heavy Metals in Sediments of Two Streams of the Olifants River System, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Addo-Bediako">Abraham Addo-Bediako</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophy%20Nukeri"> Sophy Nukeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tebatso%20Mmako"> Tebatso Mmako</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many freshwater ecosystems have been subjected to prolonged and cumulative pollution as a result of human activities such as mining, agricultural, industrial and human settlements in their catchments. The objective of this study was to investigate spatial variability of heavy metal pollution of sediments and possible sources of pollutants in two streams of the Olifants River System, South Africa. Stream sediments were collected and analysed for Arsenic (As), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Nickel (Ni) and Zinc (Zn) concentrations using inductively coupled plasma-mass mass spectrometry (ICP-MS). In both rivers, As, Cd, Cu, Pb and Zn fell within the concentration ranges recommended by CCME and ANZECC, while the concentrations of Cr and Ni exceeded the standards; the results indicated that Cr and Ni in the sediments originated from human activities and not from natural geological background. The index of geo-accumulation (Igeo) was used to assess the degree of pollution. The results of the geo-accumulation index evaluation showed that Cr and Ni were present in the sediments of the rivers at moderately to extremely polluted levels, while As, Cd, Cu, Pb and Zn existed at unpolluted to moderately polluted levels. Generally, heavy metal concentrations increased along the gradient in the rivers. The high concentrations of Cr and Ni in both rivers are of great concern, as previously these two rivers were classified to be supplying the Olifants River with water of good quality. There is a critical need, therefore to monitor heavy metal concentrations and distributions, as well as a comprehensive plan to prevent health risks, especially those communities still reliant on untreated water from the rivers, as sediment pollution may pose a risk of secondary water pollution under sediment disturbance and/or changes in the geo-chemistry of sediments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geo-accumulation%20index" title="geo-accumulation index">geo-accumulation index</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20pollution" title=" sediment pollution"> sediment pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/117190/spatial-variability-of-heavy-metals-in-sediments-of-two-streams-of-the-olifants-river-system-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4297</span> Synthesis of NiO and ZnO Nanoparticles and Charactiration for the Eradication of Lead (Pb) from Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadia%20Ata">Sadia Ata</a>, <a href="https://publications.waset.org/abstracts/search?q=Anila%20Tabassum"> Anila Tabassum</a>, <a href="https://publications.waset.org/abstracts/search?q=Samina%20ghafoor"> Samina ghafoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20ul%20Mohsin"> Ijaz ul Mohsin</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Muktar"> Azam Muktar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metal ions such as Pb2+, Cd2+, Zn2+, Ni2+ and Hg2+, in wastewater are considered as the serious environmental problem.

Most recent studies have used removing toxic heavy elements: Cu⁺², Cr⁺³ and Fe⁺³ ions from aqueous solutions has been previously investigated with different kinds of plants like kiwi and tangerines. However, in this study, three different fruit peels were used. We tested banana, peach, and potato peels to remove heavy metal ions from their solution. The first step of the experiment was to wash the peels with distilled water and then dry the peels in an oven for 48 hrs at 80°C. Once the peels were washed and dried, 0.2 grams were weighed and added into 200 mL of %0.1 percent heavy metal solutions by mass. The mixing process was done via a magnetic stirrer. Each sample was taken in 15-minute intervals, and absorbance changes of the solutions were detected using a UV-Vis Spectrophotometer. Among the used waste products, banana peel was the most efficient one. Moreover, the amount of fruit peel, pH values of the initial heavy metal solution, and initial concentration of heavy metal solutions were investigated to determine the effect of fruit peels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorbance" title="absorbance">absorbance</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title=" heavy metal"> heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=removal%20of%20heavy%20metals" title=" removal of heavy metals"> removal of heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20peels" title=" fruit peels"> fruit peels</a> </p> <a href="https://publications.waset.org/abstracts/160535/removal-of-heavy-metals-from-water-in-the-presence-of-organic-wastes-fruit-peels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160535.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4295</span> The Evaluation of Heavy Metal Pollution Degree in the Soils Around the Zangezur Copper and Molybdenum Combine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20Ghazaryan">K.

The results of the study showed that heavy metal pollution degree in the soils mainly decreased with increasing distance from the open mine and the ore enrichment combine which indicated that the open mine and the ore enrichment combine were the main sources of heavy metal pollution. The only exception was observed in the northern part of the open mine where pollution degree in the sites (along the open mine) situated 600 meters far from the mine was higher than that in the sites located 300 meters far from the mine. This can be explained by the characteristics of relief and air currents as well as the weak vegetation cover of these sites and the characteristics of soil structure. According to geo-accumulation index (I-geo), contamination factor (Cf), contamination degree (Cd) and pollution load index (PLI) values, the pollution degree in the soils around the open mine and the ore enrichment combine was higher than that in the soils around the tailing dumps which was due to the proper and accurate operation of the Artsvanik tailing damp and the recultivation of the Voghji tailing dump. The high Cu and Mo pollution of the soils was conditioned by the character of industrial activities, the moving direction of air currents as well as the physicochemical peculiarities of the soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armenia" title="Armenia">Armenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Zangezur%20copper%20and%20molybdenum%20combine" title=" Zangezur copper and molybdenum combine"> Zangezur copper and molybdenum combine</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20pollution%20degree" title=" heavy metal pollution degree"> heavy metal pollution degree</a> </p> <a href="https://publications.waset.org/abstracts/25256/the-evaluation-of-heavy-metal-pollution-degree-in-the-soils-around-the-zangezur-copper-and-molybdenum-combine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25256.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4294</span> [Keynote Talk]: Heavy Metals in Marine Sediments of Gulf of Izmir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Kam">E.

Concentrations of cadmium, copper, and zinc were measured in various body organs, viz: viscera and foot of the land snail Cantareusapertus. The snails were collected from two different sites in the Bejaia region (Northeastern Algeria), exposed to different sources of contamination by trace metals. The first sampling site is an urban areas, and the second is characterized by heavy industry, a potential source of soil pollution via heavy metal contamination. The concentrations of heavy metal in all viscera and foot samples were measured using an atomic absorption spectrophotometer. Bioconcentration of the trace metals Cu, Zn, and Cd varied between the viscera and the foot with the viscera having the highest concentration (µgg-1) of all metals than the foots; Cu, 2.03 – 5.8 (Viscera), 0.05 – 3.30 (Foot), Zn, 23.64 – 45.02 (Viscera), 1.87 – 15.15 (Foot) and Cd, 0.36 – 15.26 (Viscera), 0.18 – 13.73 (Foot), which suggest that ingestion may be the main uptake route of these essential metals. On the other hand, the levels of heavy metals varied significantly among the sampling area (P<0.001). in fact, in the foots as well as in the viscera, the concentrations of all studied metals is significantly higher in the snails sampled from sites closest to potential sources of pollution compared to those collected from urban areas characterized by moderate pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropogenic%20activities" title="anthropogenic activities">anthropogenic activities</a>, <a href="https://publications.waset.org/abstracts/search?q=Bioconcentration" title=" Bioconcentration"> Bioconcentration</a>, <a href="https://publications.waset.org/abstracts/search?q=Cantareus%20apertus" title=" Cantareus apertus"> Cantareus apertus</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title=" trace metals"> trace metals</a> </p> <a href="https://publications.waset.org/abstracts/142721/impact-of-anthropogenic-activities-on-soil-quality-using-the-land-snail-cantareus-apertus-as-bioindicator-of-heavy-metals-accumulation-in-the-bejaia-region-northeastern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142721.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4291</span> African Mesquite Exerts Neuroprotective Activity Against Quaternary Metal Mixture -Induced Olfactory Bulb-Hippocampal Oxido-Inflammatory Stress via NRF2-HMOX-1-TNF-Alpha Pathway Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orish%20E.%20Orisakwe">Orish E.

However, its neuroprotective benefits against heavy metal-induced neurotoxicity remain largely unexplored. Therefore, the objective of this study was to investigate the neuroprotective properties of African mesquite in the hippocampus and olfactory bulb against common environmental pollutants, including Cd, As, Hg, and Pb. Thirty-five albino Sprague Dawley rats were divided into five groups for the experiment. Group 1 served as the control and did not receive either the heavy metal mixture (HMM) or African mesquite. Group 2 was orally administered HMM, consisting of PbCl2 (20 mg/kg), CdCl2 (1.61 mg/kg), HgCl2 (0.40 mg/kg), and NaAsO3 (10 mg/kg), for 960 days. Meanwhile, groups 3, 4, and 5 were treated with HMM along with African mesquite at doses of 500 mg/kg, 1000 mg/kg, and 1500 mg/kg, respectively. African mesquite reduced heavy metal accumulation in the hippocampus and olfactory bulb. Additionally, Sprague Dawley rats exhibited improved performance in the Passive avoidance and Cincinnati Maze tests. Furthermore, treatment with African mesquite significantly alleviated inflammation macromolecules peroxidation. It also restored the concentrations of SOD, CAT, GSH, GPx, Hmox-1, and reduced the activity of AChE, NRF2 and NFkB and improved histopathological findings. African mesquite exhibits a multifaceted neuroprotective effect with the potential to mitigate various aspects of heavy metal-induced neurotoxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20mesquite" title="African mesquite">African mesquite</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20mixture%3B" title=" heavy metal mixture;"> heavy metal mixture;</a>, <a href="https://publications.waset.org/abstracts/search?q=neurotoxicity%3B" title=" neurotoxicity;"> neurotoxicity;</a>, <a href="https://publications.waset.org/abstracts/search?q=chemoprevention" title=" chemoprevention"> chemoprevention</a> </p> <a href="https://publications.waset.org/abstracts/168734/african-mesquite-exerts-neuroprotective-activity-against-quaternary-metal-mixture-induced-olfactory-bulb-hippocampal-oxido-inflammatory-stress-via-nrf2-hmox-1-tnf-alpha-pathway-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168734.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4290</span> Determination of Heavy Metal Concentration in Soil from Flood Affected Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nor%20Sayzwani%20Sukri">Nor Sayzwani Sukri</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hajar%20Ya%E2%80%99acob"> Siti Hajar Ya’acob</a>, <a href="https://publications.waset.org/abstracts/search?q=Musfiroh%20Jani"> Musfiroh Jani</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Khaliz%20Kedri"> Farah Khaliz Kedri</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Syuhadah%20Subki"> Noor Syuhadah Subki</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulhazman%20Hamzah"> Zulhazman Hamzah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In mid-December 2014, the biggest flood event occurred in East Coast of Peninsular Malaysia especially at Dabong area, Kelantan.

Sediments are the most important sources of pollutants as well as important future sources and carriers of pollutants. The accumulation of pollutants in sediments can cause serious environmental problems for the surrounding areas. Heavy metals (such as Cr, Cd, Al, Pb, Cu, Al, Zn) disrupt the water quality, affect the useful use of sediment, affect the ecosystem and have a toxic effect on the life of the sediment layer. This effect, which accumulates in the aquatic organisms, can enter the human body with the food chain and affect health seriously. Potential metal toxicity can be determined by comparing acid volatile sulfides (AVS) – simultaneously extracted metal (SEM) ratio in anoxic sediments to determine the effect of metals. Determination of the concentration of SEM and AVS is useful in screening sediments for potential toxicity due to the high metal concentration. In the case of SEM/AVS < 0 (anoxic sediment); in terms of AVS biomass production, its toxicity can be controlled. No toxic effects may be observed when SEM / AVS < 0. SEM / AVS > 0 (in the case of oxic sediment); metals with sensitive fraction such as Cu, As, Ag, Zn are stored. In this study, AVS and SEM measurements of sediment samples collected from five different points in the district of Tekkeköy in Samsun province were performed. The SEM - AVS ratio was greater than 0 in all samples. Therefore, it is necessary to test the toxicity against the risks that may occur in the ecosystem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AVS-SEM" title="AVS-SEM">AVS-SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=Black%20Sea" title=" Black Sea"> Black Sea</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title=" heavy metal"> heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a> </p> <a href="https://publications.waset.org/abstracts/107175/determination-of-acid-volatile-sulfides-simultaneously-extracted-metal-relationship-and-toxicity-in-contaminated-sediment-layer-in-mid-black-sea-coasts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107175.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4288</span> Application of Nanofibers in Heavy Metal (HM) Filtration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhijeet%20Kumar">Abhijeet Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Palaniswamy%20N.%20K."> Palaniswamy N.

Various water filtration techniques have been employed till now for purification and removal of hazardous metals from water. Among all the existing methods, nanofibres have emerged as a viable alternative for effective heavy metal removal in recent years because of their unique qualities, such as large surface area, interconnected porous structure, and customizable surface chemistry. Among the numerous manufacturing techniques, solution blow spinning has gained popularity as a versatile process for producing nanofibers with customized properties. This paper seeks to offer a complete overview of the use of nanofibers for heavy metal filtration, particularly those produced using solution blow spinning. The review discusses current advances in nanofiber materials, production processes, and heavy metal removal performance.

Since, irrigation with wastewater is growing in the developing countries but its suitability to environment and other health factors should be checked. Metal pollution is a very serious issue these days, various neuro, physical and mental disorders are prevailing due to the metal pollution. Waste water contaminated with heavy metals got accumulated in the soil and then bioaccumulated in the vegetables irrigated with waste water. A 3-year field experiment on cauliflower has been done by using wastewater with two different methods of irrigation i.e. Drip and Flood irrigation and checked the impact on the cauliflower and soil quality. Heavy metals (Cr, Cu, Ni, Zn and Pb) have been studied in wastewater used for the irrigation and their accumulation in the soil and vegetable was studied. The study reveals that the concentration of heavy metals increases by 100 times from initial in soil. After 3 years, the concentration of Copper(41 ppm) Chromium(39.4 ppm) Lead(62.2ppm) Zinc(100.5 ppm) and Nickel(75.7 ppm) in Flood irrigated soil while in Drip irrigated soil , Copper (36.4 ppm) Chromium(36.8 ppm) Lead(53.7 ppm) Zinc(70.3 ppm) and Nickel (53.9 ppm). In vegetable, the wastewater irrigated shows an increase in the concentration of metals with the time and the accumulation of Nickel (6.98ppm), Lead (30.18 ppm) and Zinc (55.83 ppm) in drip irrigated while in flood irrigated, Nickel (30.58 ppm), Lead (73.95ppm) Zinc (93.50 ppm) and Copper (54.58 ppm) in edible part of cauliflower which is above the permissible limits suggested by different international agencies. On other hand, the nutrients content i.e. Nitrogen, Phosphorus and Potassium in soil was increased in concentration with time. The study pointed out that the metal contaminated waste water consisting the nutrients in it but also heavy metals which causes health issues in human. While the increase in concentration of nutrients in the soil indirectly helpful to the farmers economically by restricting the use of fertilizers. But the metal pollution directly affects the health of human being. The different method of irrigation suggested that the drip irrigated vegetable acquired less metal then the flood one and is a better combo with the waste water for the irrigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation" title="drip irrigation">drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20contamination" title=" metal contamination"> metal contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water" title=" waste water"> waste water</a> </p> <a href="https://publications.waset.org/abstracts/39598/impact-of-wastewater-irrigation-on-soil-and-vegetable-quality-in-peri-urban-cropping-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4286</span> Phytoremediation of Chromium Using Vigna mungo, Vigna radiata and Cicer arietinum </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swarna%20Shikha">Swarna Shikha</a>, <a href="https://publications.waset.org/abstracts/search?q=Pammi%20Gauba"> Pammi Gauba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metal pollution in water bodies and soil is a major and ever increasing environmental issue nowadays, and most conventional remediation approaches do not provide appropriate solutions. By using specially selected and engineered metal-accumulating plants for environmental clean-up is an emerging technology called as phytoremediation. The aim of this study was to find the effect of phytoextraction of Chromium in hydroponics culture by using Vigna mungo, Vigna radiata and Cicer arietinum. The plants were allowed to grow in static hydroponic culture at 0, 50, 250, 500 and 750 ppm concentrations of Chromium dichromate. The germination percentage was determined. It was found that the germination percentage of the seeds decreased with an increase in the concentration of the heavy metals. The maximum permissible limit of Cr for Vigna radiate and Cicer arietinum was 500 ppm and toxicity was observed whereas at even at 750 ppm no toxicity was observed in Vigna mungo. The main aim of our experiment was to study the impact of Chromium on all the three selected plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title="phytoremediation">phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoextraction%20%20metal-accumulation" title=" phytoextraction metal-accumulation"> phytoextraction metal-accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutants" title=" pollutants"> pollutants</a> </p> <a href="https://publications.waset.org/abstracts/48104/phytoremediation-of-chromium-using-vigna-mungo-vigna-radiata-and-cicer-arietinum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4285</span> Wastewater Treatment from Heavy Metals by Nanofiltration and Ion Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20G.%20Kagramanov">G.

The obtained results showed that the concentrations of investigated metals are represented in the following sequence; For Gulf of Aqaba sediments Fe > Mn > Zn > Pb > Cr > Ni > Cu > Cd. While for Gulf of Suez Sediments Fe > Mn > Pb > Zn > Cu > Cr > Ni > Cd. The degree of surface sediment contamination using Geo-accumulation index (I geo) and Metal Pollution Index (MPI) was computed. Higher MPI values were observed at the sites III (Nama Bay) and VIII (Rex Beach). According to Sediment quality guidelines (SQGs) approach, Pb and Cu in the gulf of Suez at station IX (Kabanon Beach) had probably adverse ecological effects to marine organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20risk" title=" environmental risk"> environmental risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Suez%20gulf" title=" Suez gulf"> Suez gulf</a>, <a href="https://publications.waset.org/abstracts/search?q=Aqaba%20gulf" title=" Aqaba gulf"> Aqaba gulf</a> </p> <a href="https://publications.waset.org/abstracts/62062/heavy-metal-contamination-and-environmental-risk-in-surface-sediments-along-the-coasts-of-suez-and-aqaba-gulfs-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62062.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4283</span> Evaluation and Risk Assessment of Heavy Metals Pollution Using Edible Crabs, Based on Food Intended for Human Consumption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nayab%20Kanwal">Nayab Kanwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Us%20Saher"> Noor Us Saher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The management and utilization of food resources is becoming a big issue due to rapid urbanization, wastage and non-sustainable use of food, especially in developing countries. Therefore, the use of seafood as alternative sources is strongly promoted worldwide. Marine pollution strongly affects marine organisms, which ultimately decreases their export quality. The monitoring of contamination in marine organisms is a good indicator of the environmental quality as well as seafood quality. Monitoring the accumulation of chemical elements within various tissues of organisms has become a useful tool to survey current or chronic levels of heavy metal exposure within an environment. In this perspective, this study was carried out to compare the previous and current levels (Year 2012 and 2014) of heavy metals (Cd, Pb, Cr, Cu and Zn) in crabs marketed in Karachi and to estimate the toxicological risk associated with their intake. The accumulation of metals in marine organisms, both essential (Cu and Zn) and toxic (Pb, Cd and Cr), natural and anthropogenic, is an actual food safety issue. Significant (p>0.05) variations in metal concentrations were found in all crab species between the two years, with most of the metals showing high accumulation in 2012. For toxicological risk assessment, EWI (Estimated weekly intake), Target Hazard quotient (THQ) and cancer risk (CR) were also assessed and high EWI, Non- cancer risk (THQ < 1) showed that there is no serious threat associated with the consumption of shellfish species on Karachi coast. The Cancer risk showed the highest risk from Cd and Pb pollution if consumed in excess. We summarize key environmental health research on health effects associated with exposure to contaminated seafood. It could be concluded that considering the Pakistan coast, these edible species may be sensitive and vulnerable to the adverse effects of environmental contaminants; more attention should be paid to the Pb and Cd metal bioaccumulation and to toxicological risks to seafood and consumers. <p class="card-text"><strong>Keywords:</strong> <a
