Monitoramento da qualidade do ar no município de Cianorte-PR em fontes móveis

Abstract

The automotive industry is in growth which contributes to an increased amount of transit vehicles on the streets of the cities so increasing the atmospheric emissions of pollutants. The present work had as objective to monitor and analyze the concentrations of air pollutants emitted by mobile sources in three different points in the city of Cianorte - Paraná - Brazil during the period of November 29, 2013 toJanuary 10, 2014. Thus it was found that concentrations of gases like hydrogen sulfide gas (H2S), carbon monoxide (CO), oxygen (O₂) and combustible gases in locations were assessed according to the relevant legislation. Samples of pollutant concentrations recorded by portable gas meter Gas Alert Micro produced by BW Technologies were correlated with the amount of cars that passed back and forth during the time of data collection. These informations were also correlated with daily precipitation heights to see if there is some interference in the concentrations of carbon monoxide (CO). Although some concentrations have exceeded the limit imposed by the CONAMA RESOLUTION 03/1990, one of the determining factors for carbon monoxide levels have exceeded the allowed value, was the State of conservation of automobiles the more depreciated the vehicle greater influence on air quality.
