摘要
我国大气沉降型危废治理企业对环境的危害多表现在土壤重金属的积累。为研究豫东地区该类企业对周边土壤环境的影响,以豫东某典型危废治理企业为例,选取As、Cd、Cr、Cu、Pb、Hg、Ni、Zn等重金属元素,采用内梅罗综合指数法、地累积指数法及潜在生态危害指数法,开展周边土壤监测及风险评价。结果显示,企业周边土壤重金属积累明显,地累积污染贡献排序为Cd>Hg>Cu>Cr>Zn>Pb>As>Ni,Cd、Hg达到强生态危害程度。研究表明,豫东地区的大气沉降型危废治理企业周边土壤监测及污染防治,应重点关注相邻区域土壤环境,并针对发现的高污染贡献重金属,积极开展企业土壤污染隐患排查、土壤自行监测等工作。
The environmental hazards of atmospheric deposition hazardous waste treatment enterprises in China are mainly manifested in the accumulation of heavy metals in soil.To study the impact of such enterprises on the surrounding soil envi-ronment in eastern Henan,a typical hazardous waste treatment enterprise in eastern Henan was taken as an example.Heavy metal elements such as As,Cd,Cr,Cu,Pb,Hg,Ni,Zn were selected,and the Nemerow comprehensive index method,land accumulation index method,and potential ecological hazard index method were used to carry out soil monitoring and risk assessment in the surrounding area.The results showed that there was a significant accumulation of heavy metals in the soil around the enterprise,and the order of contribution to ground accumulation pollution was Cd>Hg>Cu>Cr>Zn>Pb>As>Ni.Cd and Hg reached a strong ecological hazard level.Research has shown that soil monitoring and pollution prevention in the vicinity of atmospheric deposition hazardous waste treatment enterprises in eastern Henan should focus on the soil environment of adjacent areas,and strengthen the investigation of soil pollution hazards and self-monitoring of soil in enterprises in response to the discovery of high pollution contributing heavy metals.
