Abstract: In order to investigate the residual situation of polychlorinated biphenyls (PCBs) in vegetable soils in different industrial cities in China,we analyzed the concentration,composition and sources of 11 kinds of PCBs in suburban vegetable topsoils of Changchun and Jilin cities,Jilin Province,and used the health risk assessment method to evaluate the non-carcinogenic and carcinogenic risk of PCBs pollution to exposed population.The results indicated that the mean residual quantity of PCBs in suburban vegetable soils in Jilin city was 111.0 μg·kg^-1,32.54% higher than that in Changchun city.Two cities were all given priority to high chlorinated PCBs.Principal component analysis revealed that PCBs pollution in Changchun suburban vegetable soils mainly related to transportation,automobile exhaust,paint and other industries; while the PCBs in Jilin suburban vegetable soils mainly came from the petroleum chemical industry,power industry etc.Health risk assessment showed that the cumulative non-carcinogenic in children and adults in the industrial land and residential land didn't exceed acceptable levels,the non-carcinogenic risk of PCBs was small.However,in the residential land,the cumulative carcinogenic risk of children caused by multiple exposure ways exceeded the acceptable level (10^-6).
