摘要
本文通过在天津市滨海新区局部区域汉沽和大港采集TSP和PM10样品,研究了不同颗粒物中半挥发性有机物的不同期别污染和分布特征,结果表明:半挥发性的污染水平存在明显的季节性特征,采暖期半挥发性有机物和可吸入颗粒物中苯并[a]芘浓度均远远高于非采暖期。
By taking samples of TSP and PM10 from Hangu and Dagang in Binhai New Area,this paper analyzes the pollution and distribution characterization of particulates with different sizes in heating and non-heating seasons.The results indicate that the pollution level of semi-volatile organic compounds（SVOCs） have distinct diversity in different seasons and that the concentration of SVOCs and Benzo[a]pyrene is higher in heating season than in non-heating season.
