Areceptor modeling of chemical mass balance(CMB) was used for the identification of the source of polycyclic aromatic hydrocarbons(PAHs) in atmospheric aerosols of Anyang city.The concentration of PAHs in the inhalable particles(PM_(10) = 10 μm) in winter was compared with the concentration in summer.According to the monitoring result of the air pollution sources,the main PAHs sources of Anyang were located,and the corresponding source composition table was set up too.The CMB receptor model was used for analyzing the main sharing rate source of PAHs in inhalable particles of Anyang city.This analysis result has some reference to other similar cities in North China.

通过分析3个功能区2002年4月-12月环境空气中TSP、PM10的监测结果,了解了不同月份和不同功能区TSP、PM10的污染水平及相关性,TSP与PM10比值分析结果表明,TSP、PM10质量浓度差别不大,存在相关性.通过分析安阳市环境空气中TSP月变化趋势,得出PM10和TSP的污染状况相近,都是春季最重,冬、秋季次之,夏季最轻.
