<p> Stable isotope analysis was applied to describe the poultry house environment. The poultry house indoor environment was selected for this study due to the relevant health problems in animals and their caretakers. Air quality parameters including temperature, relative humidity, airflow rate, NH<sub>3</sub>, CO<sub>2</sub> and total suspended particles, as well as mean levels of total airborne bacteria and fungi count, were measured. Carbon isotope ratios (<sup>13</sup>C/<sup>12</sup>C) were obtained in size-segregated aerosol particles. The carbon (<sup>13</sup>C/<sup>12</sup>C) and nitrogen (<sup>15</sup>N/<sup>14</sup>N) isotope ratios were measured in feed, litter, scrapings from the ventilation system, feathers and eggs. Additionally, the distribution of δ<sup>13</sup>C and δ<sup>15</sup>N values in different tissues of the chicken was examined. The airborne bacteria and fungi extracted from the air filters collected from poultry farms were grown in the laboratory in media with known isotope values and measured for stable isotope ratios. Analysis of isotope fractionation between microorganisms and their media indicated the applicability of stable isotope analysis in bulk samples for the identification of source material. The analysed examples imply that stable isotope analysis can be used to examine the indoor environment along with its biology and ecology, and serve as an informative bioanalytical tool. </p> </div> <p> <strong class="sub-title"> Keywords: </strong> Aerosol particles; carbon-13; isotope ecology; isotope fractionation; microorganisms; nitrogen-15; poultry house environment. </p> </div> <p class="disclaimer" id="disclaimer"> <a href="/disclaimer/" target="_blank" ga_category="literature_resources" ga_action="disclaimer_link" ga_label="under_abstract">PubMed Disclaimer</a> </p> <div class="similar-articles" id="similar"> <h2 class="title"> Similar articles </h2> <ul class="articles-list" id="similar-articles-list"> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/26343509/" ref="article_id=26343509&linksrc=similar_articles_link&ordinalpos=1" data-ga-category="similar_article" data-ga-action="26343509" data-ga-label=""> Verification of Egg Farming Systems from The Netherlands and New Zealand Using Stable Isotopes. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Rogers KM, van Ruth S, Alewijn M, Philips A, Rogers P.</span> <span class="docsum-authors short-authors">Rogers KM, et al.</span> <span class="docsum-journal-citation full-journal-citation">J Agric Food Chem. 2015 Sep 30;63(38):8372-80. doi: 10.1021/acs.jafc.5b01975.
