Abstract: Benzene, toluene, ethylbenzene, ethylbenzene and xylene (BTEX), emitted in animal farms, were measured in this study for 84 days. To reduce precursor VOC emission, poultry litter were covered with nanomaterial (graphene oxide, single-walled carbon nanotubes, multi-walled carbon, activated carbon, and graphite) as daily cover. The adsorbent material performances between the cabinets were compared statistically using Mann-Whitney U, Kruskal Wallis H and Wilcoxon tests. It was concluded that a decrease in pollutant emission was observed when adding carbon nanotubes. Different materials did not cause a difference in pollutant release between benzene, toluene, xylene and ethylbenzene.

Keywords: poultry litter; volatile organic compound; VOC; BTEX; nanomaterials; air pollution; climate change.
