| Abstract: | In this paper, a method was established that with hexane extraction gas chromatography- electron capture （GC - ECD） to determine organocb.lorine pesticides residues in water. The result showed that HCB, α- HCH, β- HCH, γ- HCH, δ- HCH, p, p＇ - DDD, p, p＇ - DDE, p, p- DDT, aldrin, dieldrin , endrin, heptachlor, heptachlor epoxide, o, p＇ - DDT those 14 kinds of pesticides were good separated within 14min, the recoveries of two different concentrations standard addition was from 72.0% to 121.0 %, the range of the detection limit was from 1.19 to 4.87 ng/L, and the relative standard deviation （RSD, n = 8） was 1.34% to 3.14%. The samples were detected from 10 monitoring points where in the middle of the Chishui River, only a small part out of 14 organochlorine pesticide were detected with concentration level very low. |
