RESUMO

The region of Campinas - SP in which is the city of Paulínia is responsible by 9% of the National Gross Domestic Product (NGDP) and is the third bigger industrial region of the country. 1n this region, Paulínia is the city with the biggest number of chemical and petrochemical industries and where it is installed the biggest refinery of the country and for this also possesses fuel and liquefied gas deliverers. The city is one of the industrialized regions, whose environmental scenario presents a worrying evolution condition in aspect the exhaustion of the natural resources. 1ts potential of growth in function of the installed industrial capacity, of its location and highways and railroad so is expressive. The present work has as objective to study the possible alterations in air quality due to the emissions of atmospheric pollutants in Paulínia in the different scenarios, as well as assisting in the continuity of one another work developed in the Unicamp for the Laboratory of Pollution of the Air that is the air quality monitoring in the region of with the use of a mobile laboratory. These scenarios had become possible due to the availability of the natural gas in region, since 2.000, through the Bolivia-Brazil gas-line that will go to change the fuel oil in many industries. The beginning of the natural gas consumption gives an emissions estimation for NOx is of 15,45t/day and for SO2 of 85,47t/day. Air quality estimation is based on emission inventories of the main industries in the region, design data, meteorological data and a mathematical model, used for several environmental agencies of Brazil and other countries The results gotten are isoconcentration curves of pollutants for studied area The model allows the simulation for diverse emission sources of atmospheric pollutants. Its analysis allows the identification of the most critical regions and the effect of the pollutants dispersion, the adjusted location of new emissions sources and also supply subsidies in order to get an based decisions on industrial growth in the preservation of environmental quality
