Abstract

The content and distribution characteristics of 11 kinds of polychlorinated biphenyls (PCBs) in surface soil of Changchun city suburban vegetable field were analyzed. The results showed that the contents of PCBs in soil were in the range of 27.74~219.54 g-kg-1, with the average value of 83.75 g-kg-1, which were in the moderate and unpolluted level. Variation coefficients of PCBs content were larger, indicating that PCBs contents in soil were significantly affected by human activities. The distribution characteristics of PCBs in soil were mainly come from industrial production and influenced by the dominant wind direction of the region. Principal component analysis showed that PCBs in soil were mainly come from transportation, waste incineration and volatile or leakage from paint additive, insulation materials and other industrial products.
