摘要

In order to research the influence of the distribution characteristics of OCPs (organo-chlorine pesticides) in the riparian soil of Liaohe River Conservation Area on the diversity of soil microbial communities, 17 cross-section surface soil samples in the riparian zone from upper, middle, and lower reaches of the main stream of Liaohe River in the normal flow period and the high flow period of 2013 were collected to measure the contents of OCPs in soil at different sites via the accelerated solvent extraction, silica gel and alumina chromatographic column purification and gas chromatography-mass spectrometry (GC-MS) analysis. The results show that OCPs in the riparian soil of Liaohe River Conservation Area are mainly HCHs and DDTs, with the pesticide content of DDTs slightly higher than that of HCHs; the contents of DDTs and HCHs are higher in the high flow period than that in the normal flow period, with the average contents being 0.00096 mg/kg and PJNJ UHVSHFWLYHO ?-HCH content in HCHs is the highHVWDQG?-HCH content in HCHs the lowest, suggesting that the existing HCHs in the riparian soil is not caused by previous pesticide residues.
