EVALUATION OF AIR QUALITY IN A REGION OF COAL PROCESSING AND SIDERURGIC ACTIVITIES IN THE STATE OF RIO GRANDE DO SUL, BRAZIL
Abstract:
<p align="justify"> The present work involved the determination of total suspended particles, SO<sub>2</sub> e NO<sub>2</sub> in the municipalities of Charqueadas and Sao Jeronimo, Rio Grande do Sul, Brasil. The area is marked by the presence of coal-fired power stations and siderurgic activities. The gases SO<sub>2</sub> and NO<sub>2</sub> do not affect air quality, but the results revealed contamination of air in Charqueadas due to total suspended particles. The presence of Fe, Mn, Cu, Cr, and Ni, is probably due to the steel industry. On the other hand, Pb and part of Cu and Ni can be attributed to the coal-fired power station. </p>
