| Abstract: | Concentrations of organochlorine pesticides(OCPs) were investigated in surface and deep soils from a typical chemical industrial area in Beijing.Results indicated that average concentrations of HCHs and DDXs were 5,470 ng/g and 2,110 ng/g respectively,much higher than the concentrations in agricultural and urban soils,which indicated that industrial area had been polluted by OCPs,with high OCPs concentration located at the production workshop and storage of the former pesticide plant.Principal component ana... |
