某化工厂地块土壤污染状况详细调查研究

Detailed Investigation on Soil Contamination in a Chemical Plant Plot

为避免某化工厂地块内残留的污染物可能对未来地块内及周边活动人员身体健康造成不利影响,先后对该地块开展了初步调查和详细调查工作,采集并分析土壤样品240个,地下水样品16个。土壤样品检测项目48项,地下水样品检测项目26项。根据土壤污染调查结果,该地块内土壤样品超筛选值污染物为砷、钡,部分土壤样品污染物超过建设用地第二类用地管制值;地下水超标污染物多,地下水水质较差;需尽快启动地块风险评估工作。

In order to avoid the residual pollutants in a chemical plant plot may adversely affect the health of people in and around the plot,Preliminary investigation and detailed investigation were carried out on the plot successively,and 240 soil samples and 16 groundwater samples were collected and analyzed.There were 48 soil sample testing projects and 26 groundwater sample testing projects.According to the results of soil pollution investigation,the soil samples in the plot are Arsenic,Barium,and even some soil samples exceed the second risk screening values for soil contamination of development land;the groundwater quality is poor;it is suggested to start the risk assessment of the plot as soon as possible.
