Gomes Da Silva Neto O., Alberto Lopes Burrone De Freitas C., 2015, Investigation of the Perception of the Population around a Chemical Industry in Relation to the Odor Generated by H2S, Chemical Engineering Transactions, 43, 2185-2190.
The odorous air emissions are increasingly less tolerated due to their effects on quality of life. Nuisances caused by odors in industrial emissions are a problem with high frequency of complaints of communities along the oversight agencies. Small concentrations of odoriferous substances are very likely to be issued in industrial activities and are often sufficient to affect the human olfactory system, which is highly sensitive. The present study aimed to investigate the perception of the population in the vicinity of a chemical industry with regard to odor generated by H2S. This perception was quantified by applying a questionnaire to assess the understanding of the link between odors and air pollution, and identify the main source of odors. From the results obtained it was found that the industry is primarily responsible for the emission of odorous compounds. It was found that the population perceives the presence of hydrogen sulfide gas emitted by industry, however, despite feeling uncomfortable with the odor, individuals realized that this is less than time ago, implying that the actions taken by the industry eased the problem.
