【摘要】 近几十年来,工农业的迅猛发展和化工产品的过量使用,带来了日益严重的环境问题。结合多方研究资料,总结了长江三角洲各环境介质中持久性有机污染物的含量,包括土壤、水体、沉积物和动植物体内等。总体看来,长三角各环境介质中的污染水平处于中低度水平,太湖地区尤其北部梅梁湾水体以及长江入海口近宝山样点沉积物污染水平相对较高。资料中持久性有机污染物主要以PAHs、PCBs和少量几种有机氯农药为主,其它持久性有机物例如PCDD、TBT等的研究较少。更多关于持久性有机污染物的资料,尚需要进一步完善。更多还原

【Abstract】 In recent decades,the rapid development of industry,agriculture,municipal activities and overcommitment of chemicals caused serious environmental problems.This article summarizes the published scientific data on levels of POPs in different environment mediums,including the levels in soil,water,sediments and organisms.It is shown that there existed a moderate level,the TaiHu Lake especially the MeiLiang Bay and the estuary of Yangtze river close to the BaoShan sampling stations have reached a comparatively high contamination level.The data is more about PAHs,PCBs and a few kinds of OCPs but less of other POPs like PCDD and TBT.More data on POPs are needed to complete in future research.更多还原
