Quebec.<br> (attribution: <a href='https://en.wikipedia.org/wiki/Flag_of_Quebec'>wikipedia</a>) </small> </div> <p class="bigletter">Podaci o kvaliteti zraka za <a href='/city/montreal/hr/'>Montreal</a> i <a href='/map/quebec/hr/'>Quebec</a> dostupni su već neko vrijeme, no nedavno smo dobili nekoliko pitanja o ljestvici AQI koja se koristi u ovom dijelu Kanade. Jedan od njih je od Marie A., koja je pitala:</p> <blockquote> <p>Želio bih znati zašto se indeks kvalitete zraka na vašoj web stranici razlikuje od AQI na web stranici Montreala? Preračunavate li nešto kako biste zadovoljili standarde US EPA AQI? Ako da, kako? S kojim podacima?</p> <p>Na primjer, datum 14. srpnja 14:00, većina indeksa na vašoj <a href='/city/montreal/hr/'>web stranici</a> kreće se od 53 do 65 (jedan indeks je 37) i to bi trebao biti AQI u stvarnom vremenu. Na web stranici <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>grada Montreala</a> , datum 14. srpnja 14:00, većina indeksa kreće se od 16 do 37, a također je i AQI u stvarnom vremenu.</p> <p>Dakle, možete li mi objasniti razliku i koje detalje standarda koristite?</p> </blockquote> <p>Ovo je doista vrlo dobro pitanje. a mi ćemo u ovom članku objasniti različite ljestvice koje se koriste, kako se ljestvice međusobno uspoređuju i kako se može izvršiti pretvorba.</p> <br><br> <center><br>oOo<br><br></center> <p>Kao što smo objasnili u jednom od naših <a href='faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/'>prethodnih članaka</a> , sve AQI brojke objavljene na projektu Svjetskog indeksa kvalitete zraka trenutno <sup><a href="#nowcast-footnote-1">[1]</a></sup> koriste standard US EPA. Ni Montreal ni Quebec ne očekuju ovo pravilo, tako da ovo potvrđuje da vrijednosti prikazane na stranici <a href='/city/montreal/hr/'>grad/montreal</a> koriste standard US EPA.</p> <p>Ovo je razlog razlike između očitanja projekta Svjetskog indeksa kvalitete zraka i gradske web stranice Montreala ( <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>montreal.qc.ca</a> ): Montrealska gradska EPA (Agencija za zaštitu okoliša) koristi vlastitu odgovarajuću AQI ljestvicu, koja je jasno opisana na ista web stranica. Da bi bio malo "složeniji", Quebec zapravo koristi drugu AQI ljestvicu ( <a href='http://www.iqa.mddefp.gouv.qc.ca/contenu/calcul.htm'>navedenu na ovoj poveznici</a> ) u usporedbi s Montrealom (tabarnac!). I naravno, Kanada koristi još jednu ljestvicu, nazvanu AQHI za zdravstveni indeks kvalitete zraka - ali to je nešto o čemu smo već pisali u drugom <a href='/faq/2015-06-03/overview-of-hong-kongs-air-quality-health-index'>članku</a> .</p> <br> <p>Sažetak AQI prijelomnih točaka za Montreal i Quebec naveden je u ovoj tablici:</p> <center> <table class='fancy' style='width:90%;'> <tr style='background-color:#ccf;'> <th rowspan=2>Pollutant <th colspan=2 style='border-left:2px solid black;'>Quebec <th colspan=2 style='border-left:2px solid black;'>Montreal <tr style='background-color:#ccf;font-size:12px;'> <th style='border-left:2px solid black;'>Averaging Period <th>Reference Value <th style='border-left:2px solid black;'>Averaging Period <th>Reference Value <tr> <td>Fine Particles (PM<sub>2.5</sub>) <td style='border-left:2px solid black;'>3 hours <td>35µg/m3 <td style='border-left:2px solid black;'>3 hours <td>35µg/m3 <tr> <td>Ozone (O<sub>3</sub>) <td style='border-left:2px solid black;'>1 hour <td>82 ppb <td style='border-left:2px solid black;'>1 hour <td>160 µg/m3 <tr> <td>Nitrogen dioxide (NO<sub>2</sub>) <td style='border-left:2px solid black;'>1 hour <td>213 ppb <td style='border-left:2px solid black;'>1 hour <td>400 µg/m3 <tr> <td>Sulfur dioxide (SO<sub>2</sub>) <td style='border-left:2px solid black;'>4 minutes mobile <td>213 ppb <td style='border-left:2px solid black;'>10 minutes mobile <td>500 µg/m3 <tr> <td>Carbon monoxide (CO) <td style='border-left:2px solid black;'>1 hour <td>30 ppm <td style='border-left:2px solid black;'>1 hour <td>35 µg/m3 </table> </center> <br> <center><br>oOo<br><br></center> <p>Kako bi se vrijednosti pretvorile u standard US EPA, potrebne su sirove koncentracije izražene u miligramima ili <a href='https://en.wikipedia.org/wiki/Parts-per_notation'>ppb/ppm</a> (broj čestica na milijardu/milijun).</p> <p>Nažalost, ni okrug Montreal ni Quebec ne osiguravaju te sirove koncentracije. Umjesto toga, oni samo daju očitanja kvalitete zraka koja su već pretvorena u njihove odgovarajuće AQI ljestvice. Ali to zapravo nije problem, budući da se ponovna konverzija u koncentraciju može izvesti pomoću ove jednostavne linearne formule:</p> <center><code>Raw concentration (pollutant) = Reference value (pollutant) * AQI }(pollutant) / 50</code></center> <p>Na primjer, ako je vrijednost PM <sub>2,5</sub> AQI od 18 objavljena na web stranici grada Montreala, tada je sirova koncentracija u miligramima 18*35/50 = 12,6 mg/m3. Imajte na umu da je jedinica za ozon, CO, SO <sub>2</sub> i NO <sub>2</sub> drugačija za Quebec i Montreal (ppb za Quebec - američki standard, i mg za Montreal EU standard), ali to je samo dodatna konverzija (djelomično objašnjeno u ovom <a href='/faq/2015-05-18/ground-ozone-air-quality-index-update-with-instant-cast'>članku</a> ) .</p> <p>Imajte na umu da se PM <sub>2,5</sub> AQI temelji na 3-satnom prosjeku, dok se u projektu Svjetskog indeksa kvalitete zraka koristi izvješće <a href='/faq/2015-03-15/air-quality-nowcast-a-beginners-guide/hr/'>o PM <sub>2,5</sub> Instant Cast</a> AQI po satu. Budući da nije moguće oduzeti podatke po satu od prosjeka od 3 sata, to zapravo znači da PM <sub>2,5</sub> AQI izvijestio o projektu Svjetskog indeksa kvalitete zraka za Montreal i Quebec nije baš "Instant Cast" izvješće.</p> <center><br>oOo<br><br></center> <p>I na kraju, ovdje je vizualna usporedba 3 AQI ljestvice (US EPA, Quebec i Montreal) za PM <sub>2,5</sub> i ozon (imajte na umu da se za ozon koristi jedinica ppm - tako da se konverzija iz mg u ppm vrši za Montreal) .</p> <p>Zanimljivo je primijetiti da i Quebec i Montreal koriste AQI vrijednost od 25 kao graničnu točku između Dobrog (zeleno) i Prihvatljivog (žuto), dok je za US EPA ova granična točka postavljena na 50. Dakle, sve u svemu , kada se uspoređuje jabuka s jabukom s pravom pretvorbom i prijelomnim točkama na umu, prijavljeni raspon AQI-a vrlo je sličan između standarda US EPA i standarda Quebec/Montreal.</p> <table width=100% id='pm-table'> <tr> <div id='scale-pm25'></div> <div id='scale-o3'></div> </table> <script src="/jscripts/forecast/d3.v3.min.js"></script> <script src='/air/view/faq/images/aqi-scales/scales-viewer.min.js?_=1555547488'></script><link href='/air/view/faq/images/aqi-scales/scales-viewer.css?_=1555547488' rel='stylesheet'/> <script type="text/javascript"> function doInitPage() { var scales=new AqiScale({"montreal":{"standard":{"epa":"Ville de Montr\u00e9al","url":"http:\/\/ville.montreal.qc.ca\/portal\/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL","unit":["IQA","indice de la qualit\u00e9 de l\u2019air"]},"flag":"ca","levels":[{"range":25,"title":"Bon","color":"#78a22f","description":"-"},{"range":50,"title":"Aceptable","color":"#f5dd27","description":"-"},{"range":2000,"title":"Mauvais","color":"#ef4035","description":"-"}],"units":{"o3":"ug\/m3","no2":"ug\/m3","so2":"ug\/m3","co":"mg\/m3"},"pm25":[[25,17.5],[50,35],[100,70],[200,140],[300,210],[400,280],[500,350]],"o3":[[25,0.08],[50,0.16],[100,0.32],[200,0.74],[300,1.06]]},"quebec":{"standard":{"epa":"Minist\u00e8re du D\u00e9veloppement durable, de l\u2019Environnement et de la Lutte contre les changements climatiques","url":"http:\/\/www.iqa.mddefp.gouv.qc.ca\/contenu\/index.asp","unit":["IQA","indice de la qualit\u00e9 de l\u2019air"]},"flag":"ca","levels":[{"range":25,"title":"Bon","color":"#00ce00","description":"-"},{"range":50,"title":"Aceptable","color":"#ffff00","description":"-"},{"range":2000,"title":"Mauvais","color":"#ff0000","description":"-"}],"pm25":[[25,17.5],[50,35],[100,70],[200,140],[300,210],[400,280],[500,350]],"o3":[[25,0.041],[50,0.082],[100,0.164],[200,0.338],[300,0.502]]},"us":{"standard":{"epa":"United States Environmental Protection Agency","url":"http:\/\/epa.gov","unit":["AQI","Air Quality Index"]},"levels":[{"range":50,"title":"Good","color":"#009966","description":"Air quality is considered satisfactory, and air pollution poses little or no risk","textcolor":"#ffffff"},{"range":100,"title":"Moderate","color":"#ffde33","description":"Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution."},{"range":150,"title":"Unhealthy for Sensitive Groups","color":"#ff9933","description":"Members of sensitive groups may experience health effects.
