摘要
以山东省某化工园区为研究对象,基于污染指数法、地累积指数法和潜在生态风险指数法,对周边土壤中重金属开展生态风险评价。结果表明,Zn、Cu、Ni、As、Hg在化工园区周边土壤存在富集。基于地累积指数法的评价结果显示,Hg为中度污染,Cu、As、Zn、Ni、Cr无污染。生态风险指数评价结果显示,低风险水平的取样点占83.33%,中风险水平、重度风险水平的取样点各占8.33%,主要风险因子为Hg。
Taking a chemical industrial park in Shandong province as the research object,ecological risk assessment of heavy metals in the surrounding soil was carried out based on pollution index method,land accumulation index method and potential ecological risk index method.The results showed that Zn,Cu,Ni,As and Hg are enriched in the soil around the chemical industrial park.The soil accumulation index method shows that Hg was moderately polluted,while Cu,As,Zn,Ni and Cr were pollution-free.The ecological risk index evaluation results show that the sampling points at low risk level account for 83.33%,the sampling points at medium risk level and severe risk level account for 8.33%respectively,and the main risk factor is Hg.
