Análise da qualidade do ar com base no fluxo de veículos e variáveis climáticas: o caso da cidade de Uberlândia - MG

Abstract

The air quality is a factor of extreme relevance for a healthful urban environment, since it is common the existence of great concentrations of stationary and mobile sources of atmospheric pollutants in the medium and great cities. The objective this work is to argue the main factors that determine the air quality in the city of Uberlândia - MG, showing models for the prediction of the levels of concentration of Total Suspensed Particles (TSP) and Particles with aerodynamic diameter smaller than 10 μm (PM10), generated from the method of the multiple linear regression. The variable selected for the elaboration of the models were: concentrations of pollutants, flow of vehicles, relative humidity of air, temperature of air and intensity of the winds, being overcome as base the referring daily data to the year of 2004. Models for each climatic station (summer, autumn, winter and spring) and for each period of the haste regimen of the region were elaborated (rainy and dry period).
