长江三角洲地区工业化、城市化进程迅速。于2010-2011年在长三角地区进行了有机氯农药（OCPs）和多氯联苯（PCBs）被动采样，以研究其时空分布特征，并评估其致癌风险。六氯苯、∑DDTs、∑HCHs、∑氯丹、灭蚁灵和多氯联苯的年浓度分别为151、168、18.8、110、17.9和35.0皮克/立方米。有机氯农药和多氯联苯的最高浓度一般出现在秋季和冬季。不同场地组OCPs和PCBs的平均浓度大小顺序为城市>城乡过渡>农村。吸入OCPs和PCBs的终身额外癌症风险<1.0 × 10−6。在城市、城乡过渡和农村地区，与吸入OCPs和PCB相关的每一生预测癌症病例分别为每万人12例、7例和4例。
The Yangtze River Delta (YRD) has been quickly industrialized and urbanized. Passive air sampling of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) was carried out in the YRD in 2010–2011 to investigate their spatiotemporal distributions and estimate the risk of cancer from their inhalation. Annual concentrations were 151, 168, 18.8, 110, 17.9, and 35.0 pg m−3for HCB, ∑DDTs, ∑HCHs, ∑chlordane, mirex, and PCBs, respectively. The highest OCP and PCB concentrations were generally detected in the autumn and winter. The average concentrations of OCPs and PCBs for the different site groups followed the order urban ≈ urban–rural transition > rural. The lifetime excess cancer risks from the inhalation of OCPs and PCBs were <1.0 × 10−6. The predicted cancer cases per lifetime associated with the inhalation of OCPs and PCBs are 12, 7, and 4 per ten thousand people for urban, urban–rural transition, and rural areas, respectively.
