| 摘 要： | 挥发性有机污染物可以通过渗透、淋溶、挥发等方式入侵到地下水,场地环境中包括地下水介质.采用污染场地风险评估程序四步法,通过对某有机污染场地地下水采样分析调查,分析地下水中挥发性有机污染物的浓度和分布情况,得出以下结论.该场地的浅层地下水和深度离散地下水样本中理论生存期多于癌风险均高于项目的目标水平.其中,前者风险的来源主要是PCE、TCE和VC,而后者风险值主要贡献于TCE.若该场地要将地下水作为饮用水源,则需对地下水中化合物采取进一步的措施.

| Abstract: | Volatile organic compounds can invade groundwater through infiltration, leaching and volatilization etc. , the site environment includes groundwater medium. By using four steps of risk assessment of contaminated procedures to analyze sampling investigation of the organic pollution of groundwater and the concentration and distribution of volatile organic pollutants in ground-water, following findings were achieved. For both shallow groundwater and deep discrete groundwater samples, the scores of ex-cess cancer risk in theoretical survival time were higher than the program's target. Risks of shallow groundwater mainly came from PCE、TCE and VC, while the main source of risks of deep discrete groundwater samples is TCE. If this site tends to be the source of drinking water, more measures need to be taken. |
