Abstract:

The persistent organic pollutants of 4 surface sediment samples from Yuehu Lake and Lianhuahu Lake,Wuhan City,China, were analyzed by GCMS.From the sediment samples of Yuehu Lake 124 kinds of organic compounds were detected,among which 19 kinds of chemicals belonged to priority pollutants or endocrine disruptors. While 186 kinds of organic compounds were detected in the sediment samples of Lianhuahu Lake,and 34 kinds belonged to priority pollutants or endocrine disruptors.The majority of the pollutants are phthalic acid,esters,phenol,benzene and its derivatives.The concentration of the pollutants in both of two lakes was L1＞L2＞Y2＞Y1 and the organic contamination levels in Lianhuahu Lake were higher than those in Yuehu Lake.The phthalic acid were on the highest level in all observed samples,reaching 96～98 percent of all pollutants.Bis(2ehtylhexyl)phthalate and dinbutyl phthalate were the predominant components of the analyzed pollutants with the mean of 17 599.03 ng/g dry weight.and 2 515.76 ng/g dry weight,respectively.

Key words: Lianhuahu Lake, Yuehu Lake, surface sedment, persistent organic pollutants
