Nuisances caused by odors in industrial emissions are a problem with high frequency of community’scomplaints. Some industrial activities frequently emit small concentrations of odoriferous substances andthese are often sufficient to affect the human olfactory system, which is highly sensitive. Odor emissions areless and less tolerated by society due to their effects on health and quality of life. Odorants emissions arebecoming less tolerated by society due to their effects on health and quality of life. The present study aimed toevaluate the impact of odorous substances generated by gas emissions from a chemical industry, identifyingodorous compounds by measuring the gases concentration levels and simulate their dispersion. At somepoints, fugitive H2S emissions were detected and it was noted that in the mapping plume concentration,depending on weather conditions, the plume could exceed the limits of the industry, generating uncomfortablein the population, even that the limits of perception of H2S were very low. The actions taken by the industryhave been downplaying the problem, proven even by the environmental inspection local agency.
