Investigation and Risk Assessment of Soil Pollution in a Lead-acid Battery Plot
The soil pollution investigation and risk assessment were carried out in a lead-acid battery plot.The in-vestigation results showed that the detected concentrations of characteristic pollutants in soil was 5.01～10.2 for pH,13.7～434 mg/kg for Pb and 0.07～25.4 mg/kg for Cd,which did not exceed the screening value of the sec-ond type of land.The highest concentration of characteristic pollutants in groundwater was 0.0259 mg/L for lead,0.0083 mg/L for cadmium,and 332 mg/L for sulfate,which reached the class Ⅳ water quality standard.The risk assessment results show that under the existing land use planning,the soil risk can be ignored.The groundwater is lack of effective risk exposure pathway,so the land risk is acceptable.It is suggested that long-term environmental monitoring should be carried out in the future,and land use risk management should be carried out by limiting the use of land,limiting the use of groundwater,notifying and announcing the potential risks of land,and limiting the use of land.
