抚顺市大气污染颗粒物来源特征研究

Study on the Characteristic of Source of Atmospheric Particulate pollution

在5个采样点分别采集了环境大气中的总悬浮颗粒物(TSP)和可吸入颗粒物(PM10),用富集因子分析法和化学质量平衡法解析了TSP和PM10的来源。结果表明,各主要污染源对TSP的主要分担率为煤烟尘41.6%,扬尘29.1%,冶金尘5.3%,建筑水泥1.5%,汽车尾气0.8%,燃油0.4%,有机碳21.3%;对PM10的主要分担率为煤烟尘45.8%,扬尘26.8%,冶金尘4.4%,建筑水泥0.5%,汽车尾气1.3%,燃油0.2%,有机碳20.9%。

TSP and PM_(10) in atmosphere were sampled at five sampling point,the source of TSPand PM_~10 was analyzing with enrichment factors method and chemical quality equilibrium.The result showed that,the main contribution of each main pollution source to TSP is:coal dust:41.6%,raising dust:29.1%,metallurgy dust:5.3%,cement dust:1.5%,automobile exhaust gas:0.8%,fuel oil:0.4%,OC:21.3%;to PM_~10 is :coal dust:45.8%,raising dust:26.8%,metallurgy dust:4.4%,cement dust:0.5%,automobile exhaust gas:1.3%,fuel oil:0.2%,OC:20.9%.
