| 摘 要： | 讨论了2003年宁波市颗粒物中多环芳烃浓度水平、分布及来源,结果表明,PM10中PAHS占TSP中总量的83%,PM2.5中的PAHS占TSP总量的54%,颗粒物中多环芳烃主要存在于小于10μm的颗粒中。颗粒物中多环芳烃季节变化特征明显,夏季最低,冬季最高。汽车尾气对PM10中多环芳烃的贡献率达56%,汽车尾气是颗粒物中多环芳烃的主要来源。

| Abstract: | The research on the concentration,size distribution,and source of PAH-S in particulate in air were conducted in Ningbo in 2003.The results show that PAH-S in PM-(10) and PM-(2.5) makes up 83.3% and 54% of that in TSP respectively.PAH-S is mainly contained in PM-(10).PAH-S in particulate varied with seasons.In summer the concentration of PAH-S is lowest and in winter it is highest.The exhaust of cars contribute about 56% to PAH-S in particulate. |
