Analysis of Persistent Organic Pollutants in Sediments of the Wanzhou Section of the Yangtze River

Abstract:

Organochlorine pesticides and polychlorinated biphenyls content can be obtained By measuring Wanzhou of the Yangtze River and Wanzhou Zhuxi River in sediment : Sediment content of organochlorine pesticides and polychlorinated biphenyls are increased the river down. Organochlorine pesticides in sediments are β-HCH> δ-HCH> α-HCH> γ-HCH, and pp'-DDE> pp '-DDD> op'-DDT> pp'-DDT. Organochlorine pesticides and PCBs of Wanzhou of the Yangtze River sediment in the distribution of the sampling points are similar characteristics. The main source of pollution is the direct discharge of industrial wastewater, agricultural pollution and soil erosion of farmland. Although OCPs and PCBs in water environment are very low, the impact on human health can not be ignored. Therefore certain measures are taken to clean emissions from industrial wastewater and agricultural non-point source pollution control.
