摘要

为检验污染土壤修复工程的效果

判断修复土地再利用的生态与环境风险

用人体健康风险评价法

依据土壤污染物进入人体的主要途径及可测量的参数

通过评估一块被有机物污染的场地修复前后的风险

度量了不同土地利用方式下多种土壤污染物经各种途径进入并危害人体健康的风险值及总风险。结果表明

不同土地利用方式下

苯、硝基苯、苯胺的总非致癌风险分别由修复工程实施前的4.42～46.10降低到修复后的2.50×10-3～2.61×10-2

总致癌风险则分别由3.06×10-6～7.41×10-6降低到4.75×10-7～1.19×10-6

修复后的土地适宜作为商业服务或工业用地。

Abstract

In order to evaluate soil remediation and to judge ecological and environmental risk of the reuse of the sites where soil is remedied

the method of human health risk assessment is applied.Based on the approaches that soil pollutants enter into human body and the specific assumption parameters

a site contaminated by organic chemicals was evaluated and the human health risks

which are caused by many soil pollutants entering into human body through various approaches in different land uses and harming human health

were calculated.Results indicated that in the different land uses

the integrated noncarcinogenic risk of benzene

nitrobenzene

and aniline decreased from 4.42～46.10 to 2.50×10-3～2.61×10-2 and the integrated carcinogenic risk decreased from 3.06×10-6～7.41×10-6 to 4.75×10-7～1.19×10-6 after soil remediation.The site after soil remediation is suitable to business and industry in the future.
