Investigation on Soil Pollution and Health Risk Assessment of an Industrial Decommissioned Land in Shanghai
In this paper,an industrial decommissioning land in Shanghai was taken as the research object,and soil pollution investigation and health risk assessment were carried out in accordance with the Technical Guidelines for Soil Pollution Investigation on Construction Land(HJ 25.1-2019)and Technical Guidelines for Soil Pollution Risk Assessment on Construction Land(HJ 25.3-2019)and other technical specifications.The results showed that the excessive contaminants in the soil were nickel,antimony and petroleum hydrocarbons(C10-C40),and all the pollutants were distributed in the filling soil.The pollutants exceeding the standard of groundwater are arsenic,antimony and petroleum hydrocarbons(C10-C40).The health risks of nickel and antimony in soil to potentially sen-sitive receptors exceeded the acceptable range,and the comprehensive risk control values were 240 mg/kg and 20 mg/kg,respectively,and the total amount of earth needed to be repaired was 478 m3.
