Distribution and sources of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in surface waters of Jinzhou Bay in China

摘要：

　　Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in surface water collected from the Jinzhou Bay in North China were analyzed using gas chromatography to reveal their horizontal distribution tendencies and trace their sources.Total PCB concentrations ranged from 215.4 to 3161 ng/L.The level of PCB in the opening of the Bay was higher than the inner Bay.The predominated components were 5-and 6-chlorinated PCBs,indicating these residual PCBs derived from paint additives.Total OCP concentrations ranged from 4.165 to 136.8 ng/L,whose isomer concentrations ratios implied the usage of technical HCH and lindane.
