| 摘 要： | 焦炉炼焦产生多环芳烃物质(PAHs)具有较强毒性和致癌作用,本研究以某大型钢铁企业焦炉为例,采用AERMOD扩散模式来预测分析焦炉排放PAHs共13种污染物在大气中迁移扩散情况,采用BREEZE Risk Analyst根据人体健康风险评价导则HHRAP计算评价范围内受体人群PAHs污染物致癌和危害指数,对焦炉排放PAHs的健康风险进行了定量评价.结果表明,应重点关注焦炉排放萘危害指数值影响(最大值为0.97).焦炉排放各污染物单因子致癌风险均小于1.0E-06,而综合考虑多环芳烃总致癌风险值最大达到2.65E-06,对当地居民的人体健康可能存在一定的影响.

| Abstract: | Polycyclic aromatic hydrocarbons (PAHs) produced by coke oven are with strong toxicity and carcinogenicity. Taken typical coke oven of iron and steel enterprises as the case study, the dispersion and migration of 13 kinds of PAHs emitted from coke oven were analyzed using AERMOD dispersion model, the carcinogenic and non-carcinogenic risks at the receptors within the modeling domain were evaluated using BREEZE Risk Analyst and the Human Health Risk Assessment Protocol for Hazardous Waste Combustion (HHRAP) was followed, the health risks caused by PAHs emission from coke oven were quantitatively evaluated. The results indicated that attention should be paid to the non-carcinogenic risk of naphthalene emission (the maximum value was 0.97). The carcinogenic risks of each single pollutant were all below 1.0E-06, while the maximum value of total carcinogenic risk was 2.65E-06, which may have some influence on the health of local residents. |
