| 摘 要： | 以北京某大型焦化厂苯污染地下水为例,对该场地不同功能地块苯呼吸暴露途径的致癌风险进行了评价,计算了苯的修复目标、修复范围并提出了相应的修复策略.结果表明,室内呼吸含苯的蒸气为关键暴露途径.该途径下,规划为商业用地的地块A苯的致癌风险为6.37×10-8,未超过1.0×10-6,风险可接受.但规划为工业遗址公园的地块B及规划为综合开发区的地块C苯的致癌风险分别为2.20×10-4、7.49×10-5,均超过可接受风险水平.为使风险可接受,该场地地下水应修复至118μg.L-1以下,需修复的地下水面积约为16.5万m2.综合考虑该场地地下水含水层的高渗透性及苯的强挥发性,确定削减污染源强度的空气注射技术并辅以切断暴露途径的工程控制措施为该场地苯污染地下水的优先修复策略.
