Studies on Residual Characteristic and Assessment of Organochlorine Pesticides in Water of Chaohu River Tributaries
The concentrations of 19 kinds of OCPs in water of Chaohu River tributaries were analyzed by SPE-GC/ECD in this paper.The samples were from NanFei river,ShangPai river,FengLe river,HangBu river,ZheGao river and Bai Shi-shan river.According to the experiment,there were 8 kinds of detected OCPs,mainly of HCHs,DDTs,β-Endosulfan,etc.The range of total OCPs concentration was 1.22~77.10ng/L.The results indicated that the main components were HCHs and DDTs.And the primary residual HCHs were β-HCH.The primary residual DDTs were DDE and DDD.The origins of OCPs in the watershed were investigated showed that there were historical residues and recent discharges of OCPs into the watershed.The concentrations of all existences accorded with the target values of GB 3838-2002.Compared with other water bodies throughout the world,the concentrations of OCPs in the surface water of the Chaohu River are much lower,and the risk is low in general.
