Hexachlorocyclohexane (HCH) was one of the major organochlorine pesticides (OCPs) in the water and sediments of the Peacock River in Xinjiang, China. Analyzing the water and sediment samples by gas chromatography–electron capture detection (GC-ECD), it showed that all the HCH isomers (α-HCH, β-HCH, γ-HCH and δ-HCH) could be found in the sediment, and the range was from 0.13 ng/g to 6.58 ng/g. The ratios of α-HCH/γ-HCH at all the sites (except Site 2 and Site 6), were below 1.5, and it appeared that the sediment environment changed recently (there was newly input of γ-HCH) and the Bosten Lake was the most possible source. In the water, only β-HCH could be detected, the range was from N.D. to 0.019μg/L. Discuss the influencing factors of HCH solubility: it showed that the high salinity reduced the solubility of HCHs into the water, and the alkalescence increased the solubility.
