Distribution patterns of polychlorinated biphenyls in soils collected from Zhejiang province, east China.
Polychlorinated biphenyls (PCBs) were determined in surface soil samples from Zhejiang Province, east China. Concentrations of total PCBs ranged widely from 7.50 to 263 ng kg(-1) with a mean value of 45.4 ng kg(-1) (dry matter basis). In general, concentrations in soil samples from the southern part of the test area and especially from some sites near hills tended to be higher than those from other sites. The prevailing winds may have been the main factor influencing the spatial distribution of PCBs in soils. Other factors may have included the distribution of residential areas and land use variables. In this paper we also discuss the relationships between OCPs and PCBs in soils and relationships between these and land use variables as revealed by correlation analysis.
