摘要
研究了沈阳市环境空气中不同颗粒物的污染程度、分布特征及颗粒物组成,研究结果表明沈阳市TSP、PM10和PM2.5整体污染水平较高,PM10以下颗粒比例较高;重金属主要吸附在细小颗粒物上。
The pollution degree, distribution character and the composition of different atmospheric particles in Shenyang were studied. The result showed that the pollution degree of TSP, PM10 and PM2.5 were serious, the proportion of particles under PM10 was high and the heary metals were mainly adsorbed by small particles.
