The Correlation of Sediments Characteristics with Organochlorine Pesticides (OCPs) in Surface Sediments of Nansi Lake, China

摘要

The correlations of sediment characters[total organic content (TOC), particle size, soluble salt] with organochlorine pesticides (OCPs) in seven surface sediment samples of Nansi lake were discussed. Organochlorine pesticides(OCPs) in seven surface sediment samples of Nansi lake were analyzed by GC／ECD(Gas chromatography with electrochemical detection). The result showed that OCPs content was 2.9-6.91ng/g dw (dry weight). The concentrations of organochlorine pesticides (OCPs) failed to correlate with sediment characteristics (TOC, particle size and soluble salt).
