【摘要】：目的研究电子垃圾拆解地区经口暴露多氯联苯(PCBs)对人群健康产生的潜在健康危害。方法运用美国环保署人群健康风险评估模型,评估电子垃圾拆解地区经口暴露多氯联苯对人群的致癌和非致癌风险。结果电子垃圾拆解地区水、稻米、包心菜、鸡蛋和鲫鱼中PCBs含量均高于对照区(均P0.05);人群健康风险评估结果表明拆解区成年男性、成年女性和儿童经口暴露PCBs的非致癌风险分别为2.53×10-6、3.04×10-6、2.14×10-6,均高于美国环保局定义的人群风险水平值(1×10-6);拆解区成年男性、成年女性和儿童人群经口暴露PCBs的致癌风险分别为4.34×10-5、5.20×10-5、9.72×10-6,对照区人群经口暴露PCBs的致癌风险分别为4.45×10-6、4.61×10-6、1.37×10-6。结论电子垃圾拆解产生的PCBs已对当地环境造成一定程度的污染,并对当地人群存在潜在的健康风险。
[Abstract]:Objective to study the potential health hazards of PCBsexposed to PCBs in electronic waste dismantling area. Methods the population health risk assessment model was used to evaluate the carcinogenic and non-carcinogenic risk of PCBs exposed to PCBs in electronic waste dismantling areas. Results PCBs contents in water, rice, cabbage, eggs and crucian carp were higher than those in control area (all P 0.05). The non-carcinogenic risk of oral exposure to PCBs in adult women and children was 2.53 脳 10-6, 3.04 脳 10-6N, 2.14 脳 10-6, respectively, which was higher than the population risk level of 1 脳 10-6 as defined by the US Environmental Protection Agency. The carcinogenic risk of oral exposure to PCBs in adult women and children was 4.34 脳 10-55.20 脳 10-50.72 脳 10-6, respectively. The carcinogenic risk of oral exposure of PCBs in control area was 4.45 脳 10-60.61 脳 10-6 (1.37 脳 10-6), respectively. Conclusion PCBs produced by electronic waste disassembly have caused a certain degree of pollution to the local environment and have potential health risks to the local population.
