| 摘 要： | 在滨海新区局部区域汉沽和大港采集了TSP和PM10样品,分析了不同颗粒物中多环芳烃的不同期别污染和分布特征,结果表明,多环芳烃的污染水平存在明显的季节性特征,采暖期多环芳烃和可吸入颗粒物中苯并a]芘浓度均远远高于非采暖期。多环芳烃在不同期别也有不同的分布特征,非采暖期均是高环类多环芳烃占主导地位,比例超过60%;而在采暖期则是中环类多环芳烃占主导。

| Abstract: | Sampling the TSP and PM10 in Hangu and Dagang, analyzing pollution and distribution characterization on particle with different sizes in heating and non - heating season. The results indicate ： pollution level of PAHs exist distinct diversity in different season, the concentration of PAHs and Benzol a] pyrene are higher in heating season than non - heating season. PAHs have different distribution characterization in different seasons, high ring PAHs occupy dominant, the proportion exceed 60% ; middle ring PAHs occupy dominant in non- heating season. |
