Soil Heavy Metal Pollution Characteristics and Ecological Risk Assessment of a Closed Lead Acid Battery Enterprise
摘要
Abstract
In order to find out whether a lead acid battery enterprise in Jiangsu Province caused soil pollution after shut down of the production for 6 years,samples of 8 heavy metals in the soil,including Pb,Cu,Zn,Hg,As,Cd,Ni and Cr,were analyzed.based on principal component analysis and radial basis function(RBF)interpolation method,the pollution distribution characteristics of heavy metals in the soil of the plot were analyzed.The single factor index method and Nemerow comprehensive index method were used to analyze the soil environmental quality of the contaminated plots,and the Hakanson potential ecological hazard index method was used to carry out the comprehensive evaluation for the ecological risk assessment involving human health.The results indicate that the soil in the study area has suffered significant anthropogenic exogenous heavy metals pollution,and the concentration of local heavy metals is relatively high.The vertical pollution area is mainly concentrated in the soil above 100 cm.The overall pollution level of the area is mild pollution,and the local soil of the hazardous waste storage is moderately polluted.It is recommended to conduct further risk assessment and remediation of the soil in this unit.There is no potential ecological risk in the soil of the study area,but special attention should be paid to the soil environmental quality of the hazardous waste storage structure units.The main threat is cadmium in the soil,and its EiCd potential ecological risk index has reached a strong level.It was suggested that this plot should not be used as agricultural land or local soil restoration and treatment in the subsequent development and utilization.关键词
