The main purpose of the present work is to study the concentration of atmospheric particles in the Candiota region, in the state of Rio Grande do Sul, where the Presidente Médici coal power plant is located. Aerosol samples were collected at the studied locations between December 2000 and December 2001 during 24 h periods at 15 day intervals using HV PM10 and dichotomous samplers. Then, the values obtained with the ISCST (Industrial Source Complex Term) model, with the HV PM10 sampler at all studied stations, and with the dichotomous sampler at the 8 de Agosto station were compared with each other. The results show that the values for the model had been underestimated in relation to the HV PM10 data for the studied stations, but agreed with the values obtained with the dichotomous sampler.
本研究的主要目的是调查南里奥格兰德州坎迪奥塔地区（Presidente Médici 燃煤电厂所在地）的大气颗粒物浓度。2000年12月至2001年12月期间，每隔15天，使用HV PM10采样器和二分采样器在研究地点采集24小时的气溶胶样本。然后，将ISCST（工业源复合模型）模型在所有研究站点使用HV PM10采样器得到的值，与8月8日站点使用二分采样器得到的值进行比较。结果表明，该模型得到的值相对于研究站点的HV PM10数据被低估，但与二分采样器得到的值一致。
