主　　题：polycyclic aromatic hydrocarbons phthalic acid esters Yangtze River Delta surface water 

摘      要：The pollution from polycyclic aromatic hydrocarbons（PAHs） and phthalic acid esters（PAEs） in the surface water of the rapidly urbanized Yangtze River Delta region was *** surface water samples were collected in June *** samples were liquid-liquid extracted using methylene chloride and analyzed by gas chromatography-mass *** of PAHs and PAEs ranged 12.9-638.1 ng/L and 61-28550 ng/L,***,naphthalene,pyrene,phenanthrene,di-2ethylhexyl phthalate,and di-n-butyl phthalate were the most abundant compounds in the *** water samples were moderately polluted with benzo[a]pyrene according to China＇s environmental quality standard for surface *** two highest concentrations of PAHs and PAEs occurred in samples from Taihu Lake,Wuxi City and the western section of Yangchenghu *** sources of pollution at S7 were petroleum combustion and the plastics industry,and at Yangchenghu Lake were petroleum combustion and domestic *** in samples from the Beijing-Hangzhou Grand Canal originated from diesel *** were no obvious sources of pollution for the other water *** results can be used as reference levels for future monitoring programs of pollution from PAHs and PAEs.
