摘要
多环芳烃(PAHs)作为一种持久性有机污染物,广泛分布于我国环境介质中。作为我国发展较快的典型城市,本文总结了上海市各环境介质中PAHs的污染水平及其来源。上海市大气中PAHs随季节变化明显,在我国范围内污染较小。PAHs污染已普遍污染水体,部分水体污染较为严重。土壤PAHs污染较为严重,特别是工业区土壤已经严重超标。而上海市部分区域植物中PAHs含量较高,食物中PAHs含量较低,污染较小。上海市各介质PAHs的来源以燃烧源为主,特别是生物质和石油煤炭的燃烧,这与本区域城市化水平和经济发展特征密切相关。
Polycyclic aromatic hydrocarbons(PAHs),as a persistent organic pollutant,are widely distributed in environmental media in China.As a typical city with rapid development in China,the pollution levels and sources of PAHs in various environmental media in Shanghai have been summarized.The atmospheric PAHs in Shanghai vary significantly with the seasons.PAHs pollution has been generally polluted by water bodies,and some water bodies are seriously polluted.The pollution of soil PAHs is more serious,especially in the industrial area.In some areas of Shanghai,the content of PAHs is high,the content of PAHs in food is low,and the pollution is less.The sources of PAHs in various media in Shanghai are mainly combustion sources,especially the burning of biomass and petroleum coal,which is closely related to the urbanization level and economic development characteristics of the region.
