The concentrations of the water samples were from 564. 04 to 1209. 41 ng/L with the mean of 965. 64ng/L. The concentrations of surface sediment samples were from 8500. 26 to 23347. 20ng/g(DW) with the mean of 14832. 04ng/g (DW). Phthalic acid ester was the major pollutants. Phthalic acid ethyl hexyl ester and Phthalic acid dibutylester were the highest pollutants. Polycyclic aromatic hydrocarbon, Methyl nitro-benzene and Isophorone have been detected in the water and sediment samples. The highest concentration of the pollutants found the previous sewage outfall. The total concentration of 25 SVOCs in surface sediment nearly times of that in water. %R 10.18307/2010.0407 %U http://www.jlakes.org/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
