中文摘要
      选择郑州市3家典型碳素企业,研究了不同功能区的挥发性有机污染物(volatile organic compounds,VOCs)的排放特征及其臭氧生成潜势(ozone formation potential,OFP),并利用美国环保署(EPA)的健康风险评价模型对碳素行业排放的VOCs的健康风险进行了初步评价.结果表明,3家企业生产区VOCs质量浓度在89.77~964.60 μg·m-3之间,管理区在51.46~121.59 μg·m-3之间,萘和二硫化碳是碳素企业厂区内浓度最高的污染物;生产区VOCs的臭氧生成潜势在75.42~1416.73 μg·m-3之间,管理区在65.32~202.42 μg·m-3之间,主要来自于芳香烃和烯烃的贡献.生产区VOCs致癌健康风险(Risk)为3.5×10-5~2.8×10-3,管理区为2.0×10-5~9.4×10-5,高于EPA推荐的最大可接受水平(10-6);生产区VOCs非致癌健康风险危害指数(hazard index,HI)为3.2~1.4×102,管理区为4.3×10-1~3.8,除企业甲的管理区外均大于1,可能会对暴露人群的健康造成致癌和非致癌危害.
英文摘要
      The three typical carbon enterprises in Zhengzhou were selected as research targets, and the emission characteristics of volatile organic compounds (VOCs) and their ozone formation potential (OFP) in different functional areas were studied. The US Environmental Protection Agency (EPA) health risk assessment model was used to evaluate the health risks of VOCs emitted by the carbon industry. The results showed that the concentration of VOCs in the production areas of the three research enterprises was between 89.77-964.60 μg·m-3, and the management area was between 51.46-121.59 μg·m-3. Naphthalene and carbon disulfide were at the highest concentrations in the carbon plants. The ozone formation potential of VOCs in the production area was between 75.42-1416.73 μg·m-3, and in the management area was between 65.32-202.42 μg·m-3, mainly from the contribution of aromatic hydrocarbons and olefins. The carcinogenic health risk (Risk) of VOCs in the production area was 3.5×10-5-2.8×10-3, and in the management area was 2.0×10-5-9.4×10-5, which was higher than the maximum acceptable level recommended by the EPA (10-6). The non-carcinogenic health risk index (HI) of the VOCs in the production area was 3.2-1.4×102, and in the management area was 4.3×10-1-3.8, except for the management area of the first enterprise, which was greater than 1, which may expose the workers. These health factors cause cancer and non-carcinogenic hazards.
