In order to gain comprehensive understanding of status, properties and sources of PCBs pollution at an industrial area in Shanghai, PM10 were collected during the period November 2004-September 2005. The results showed that the mean value of total PCBs in the industrial area was 2,017.22 pg m(-3). Three dioxin-like PCB congeners had a mean value of TEQ of 0.24 pg-TEQ m(-3). The concentrations of PCBs at all sites were higher in colder months than in warmer months. SigmaPCB concentrations were correlated positively with SO2, NO2 and OCPs, while negatively with polycyclic aromatic hydrocarbons (PAHs), ambient temperature, rainfall and wind speed. It could be concluded that the area had been contaminated by PCBs from a local source.
为全面了解上海某工业区多氯联苯(PCBs)污染状况、特性及来源,于2004年11月至2005年9月期间采集了PM10样本。结果显示,该工业区多氯联苯总量的平均值为2017.22皮克/立方米。三种类二噁英多氯联苯同系物的毒性当量(TEQ)平均值为0.24皮克-TEQ/立方米。所有采样点的多氯联苯浓度在较冷月份高于较暖月份。多氯联苯总量(∑PCB)浓度与二氧化硫、二氧化氮和有机氯农药呈正相关,而与多环芳烃(PAHs)、环境温度、降雨量和风速呈负相关。可以得出结论,该区域已受到来自本地源多氯联苯的污染。
