Abstract
The levels of DDTs, HCHs and PCBs in topsoil, cereal and irrigation water from typical industrial and agricultural areas of Jilin Province in Northeastern China were evaluated by using gas chromatography coupled with an electron capture detector. The amount of ∑OCPs and ∑(7)PCBs found in topsoils ranged from 24.7 to 98.0 and 17.2 to 98.7 ng g(-1), respectively. The geometric means of ∑HCHs, ∑DDTs and ∑(7)PCBs in rice stem samples were 28.9, 32.4 and 49.0 ng g(-1), respectively. The average level of total OCPs concentration in rice field water in Meihekou area (0.849 ng g(-1)) is higher than that in Jilin area (0.178 ng g(-1)) and all OCPs concentrations in rice field water met the water quality standards for Grade I regulated by China's national environmental quality standard of surface water.
