家具制造企业密集区空气中VOCs污染状况及健康风险评价

Pollution Situation and Health Risk Assessment of Volatile Organic Compounds from Dense Area of Furniture Manufacturers

采用Tenax管吸附-热脱附-气相色谱法测定家具制造企业密集区空气中挥发性有机物(VOCs),并应用美国国家环保局(USEPA)的健康风险评价模型评估其对周边人群的影响。结果表明,家具制造企业密集区总VOCs的质量浓度为0.931 mg/m3,11种目标物中乙酸乙酯、丙酮和乙酸丁酯所占比例较高,分别占总VOCs的20.2%、10.7%和9.1%。该区总VOCs的累积非致癌风险指数为3.47×10-7,低于1,不会对人体产生明显的非致癌健康危害;其累积致癌风险指数为2.49×10-5,是可接受致癌风险值(1.0×10-6)的25倍,可能对人群存在致癌影响。

Volatile organic compounds （VOCs）in the air of an area where furniture manufacturers densely located were monitored and analyzed using sorbent adsorption-thermal desorption-gas chromatography,and the as-sessment of health risk was conducted referred to the US EPA evaluation model.The results showed that the total mass concentration of VOCs was 0.931 mg /m3 .Ethyl acetate,acetone and butyl acetate accounted for 20.2%, 1 0.7% and 9.1 % respectively.The non-carcinogenic risk index of VOCs was 3.47 ×1 0^ -7 ,which was non-carci-nogenic to human body in the area.However,the carcinogenic risk index of VOCs was 2.49 ×1 0^ -5 and was 25 times higher than the public acceptable risk value （1 .0 ×1 0 ^-6 ）.
