摘要
对江苏某化工区及其周围地区(农业区)34个浅层地下水样点的水质测试结果进行了统计分析。结果表明:91项有机测试指标中检出16项,其中,检出率较高的有二氯甲烷、菲、荧蒽、芘、β-BHC和萘。在平面分布上,化工区内样点检出有机物的种类和项数均大于周围地区(农业区),说明该区有机污染程度与化工企业的分布密切相关;挥发性有机物二氯甲烷可通过大气干湿沉降作用污染浅层地下水。
The quality analysis of shallow groundwater in a industrial zone and several neighboring agricultural zone in Jiangsu indicates that 16 of the 91 organic detection index exist in the groundwater. The detection rates of dichloromethane, phenanthrene, fluoranthene, pyrene, β- BHC and naphthalene are hightest. As organic pollutants in industrial zone are more than those in agricultural zone, organic pollution level closely related to the distribution of industrial factories. Diehloromethane is volatile and pollute shallow groundwater through atmospheric deposition.
