Distribution characteristics of organochlorine pesticides in karst subterranean river in Liuzhou
摘要
Abstract
Water samples collected from different positions of two subterranean rivers in Liuzhou Karst Area are tested for 18 kinds of organochlorine pesticides(OCPs) by gas chromatography coupled with an electron capture detect (GC/ECD). The results show that except dieldrin aldehyde, 17 kinds of OCPs are detected in different levels and the OCPs concentration range from 107. 68 to 1 101. 55ng/L, with a mean value 532. 515ng/L. Main OCPs are α-HCH, β-HCH, γ-HCH, δ-HCH, p,p'-DDE, o,p'-DDT, p,p'-DDD, p,p'-DDT, HCB, Heptachlor, Aldrin. Content of the DDTs is the highest. HCHs and OCPs account for 75.8％～96％ of the total. Meanwhile, the origins of organochlorinated pesticides in the water are investigated.DDTs mainly comes from soils. HCHs source is relatively complex, probably originated from industry or long atmospheric transport. Recently use of lindane can also make HCHs input concentration increase. Comparing concentration of OCPs in different kinds of water from the world, organochlorine pesticides content is relatively at high level in these two karst underground rivers.关键词
