| 摘 要： | 以江苏省某废弃染料厂搬迁后的遗留地块为研究对象，运用内梅罗综合污染指数法对场地有机污染物污染程度进行评估，并结合Surfer软件中克里金插值法研究有机污染物的健康风险空间分布情况。结果表明:该场地主要超标污染物为氯仿和苯并（a）芘，污染区域主要为生产车间，最大超标深度为12 m，苯并（a）芘在1.5，3.0 m深土壤中对暴露人群造成的致癌风险高，氯仿在6，12 m深的土壤中致癌风险高；但它们在各层中所造成的危害商均<1。因此，该场地开发利用前需进行土壤修复。

| Abstract: | Taking the leftover plot after the relocation of an abandoned dye factory in Jiangsu Province as the research object, the Nemero comprehensive pollution index method was used to assess the pollution degree of organic pollutants on the site, and the kriging interpolation method in Surfer software was used to simulate and analyze the spatial distribution of health risks of organic pollution factors. The results showed that the main pollutants exceeding standard in this site were chloroform and benzo (a) pyrene. The production workshop was the main polluted area. The maximum depth exceeding the standard was 12 m. Benzo (a) pyrene had a high carcinogenic risk to the exposed people in 1.5 m and 3.0 m deep soils, and chloroform had a high carcinogenic risk in 6 m and 12 m deep soils, but their hazard quotients in each layer were less than 1, so the site soil needed to be repaired before development and utilization. |
