Abstract: Content characteristics of polychlorinated organic pollutants (PCOPs) in vegetable were studied by using the method of field investigation and sampling, potted plant in glasshouse and laboratory analyses. Results showed that several PCOPs were detected in vegetables sampled from field, and the contents of chlorobenzene (CBs), hexachlorocyclohexane (HCHs) and dichloro- dipjenyl -trichloroethane (DDTs) in vegetables were 14.039±9.176, 7.412±6.096, 5.553±6.772 ng/g, respectively. The contents of PCOPs in garlic and cabbage were higher than others. The contents of PCOPs in potted vegetables were related with the contents of PCOPs in potted soil, and the contents of PCOPs in potted vegetables increased with increase of soil PCOPs.
