| 摘 要： | 本研究以某典型焦化厂建构筑物及生产设施为对象,从不同功能区、不同材质等角度分析建构筑物及生产设施表面多环芳烃(PAHs)的赋存特征,并评价其健康风险.结果表明,焦化厂建构筑物及生产设施表面的PAHs含量范围为8. 00×10~(-2)～1. 98×102μg·dm~(-2).其中,22. 0%的擦拭样品PAHs含量超出了世界贸易中心工作组(WTCTG)的规定限值(1. 45μg·dm~(-2)),PAHs最大超标可达135倍.PAHs含量高值主要分布在炼焦区和精制区,其中,炼焦区样品PAHs含量均值最高,达12. 1μg·dm~(-2).研究区中防锈漆材质表面PAHs含量均值和超标率最高,砖和水泥次之,玻璃对PAHs的吸附和富集能力最小.采用美国超级基金方法对各功能区开展健康风险评估研究,其中,炼焦区及精制区内PAHs存在致癌风险,其致癌单体对暴露人群的总致癌风险值可达3. 78×10~(-6)～1. 32×10~(-5),均高于US EPA标准下限10~(-6).场地建构筑物及生产设施表面的有机污染物分布规律及健康风险结果可为污染场地环境管理和治理对策提供科学依据.
