摘　　要：土壤中一些污染物浓度尽管可达到相关土壤质量标准,但当其之上建有建筑物后,由于污染物蒸气会通过裂隙、管道边缘等入侵建筑物而造成危害。选取某硝基苯生产企业搬迁后的场地作为研究对象,在分析土壤污染物蒸气入侵建筑物的途径与危害的基础上,利用Johnson&Ettinger模型预测未来在该场地上建设的建筑物的室内苯和硝基苯蒸气挥发暴露浓度,并依据相关环境空气质量标准对其进行了环境影响评价。结果表明:研究场地部分点位中苯和硝基苯蒸气的室内挥发暴露浓度已超标,将会对环境和人体健康构成一定的危害。最后提出了减轻土壤污染物蒸气入侵危害的对策与措施。In soil some pollutant concentrations may meet the soil quality standard, the pollutant can intrude into buildings through cracks and pipe edge. This paper takes an abandoned nitrobenzene production site as the study object,analyzes the harm and path of vapor intrusion, applies Johnson ＆ Ettinger model to predicting the volatile exposure concentrations of benzene and nitrobenzene in the building constructed on the site,and evaluates the environmental impact based on the related ambient air quality standards. Research shows that the indoor volatile expo sure concentration of benzene and nitrobenzene vapor will exceed the standard in some points in the building,which will compose a certain harm to the environment and human health. At last,the paper presents some possible counter measures for reducing intrusion harm of soil contaminant vapor.
