Abstract:: The distribution and sources of PAHs in the surface sediment in Nansihu Lake were analyzed and the ecological risk of the lake was evaluated through examining 16 PAHs setting by EPA in 9 samples of the surface sediment of Nansihu Lake. The results showed that the content of PAHs in estuary was the highest and was influenced by the seriously polluted rivers from which flew into the lake. The contents of PAHs in the samples near the Weishan Island and the second dam were much higher than in the samples of the internal lake which was higher in the higher lake than in the lower lake. The PAHs in the surface sediment mainly come from the incomplete combustion, but it also contained some oil pollution. The ecological risk of the surface sediment in Nansihu Lake was low and had not adversely affected the creatures. So the organic pollution belonged to the slight contamination in the lake.
