摘要
重金属污染是造成生态环境污染的主要因素,为此研究农耕表层土壤重金属污染生态风险预警方法,旨在提高生态环境和农产品的质量安全。以济宁市某农耕区域为预警评估对象,对其实施采样、处理和样品分析。根据重金属元素含量统计分布,利用综合污染指数法(Pi)与潜在生态风险评价法(RI)划分各重金属元素污染等级和潜在生态风险指数。通过生态风险指数法(I_(ER))实现农耕表层土壤重金属生态风险预警评估。通过对研究区测试,得出所提方法能够准确实现农耕表层土壤重金属污染生态风险预警。
Heavy metal pollution is the main factor causing ecological environmental pollution.Therefore,the early warning method of ecological risk of heavy metal pollution in agricultural topsoil is studied in order to improve the ecological environment and the quality and safety of agricultural products.Taking a farming area in Jining as an early warning evaluation object,sampling,processing and sample analysis were carried out.According to the statistical distribution of heavy metal elements,the comprehensive pollution index method(Pi)and the potential ecological risk assessment method(RI)are used to divide the pollution levels and potential ecological risk indexes of each heavy metal element.The ecological risk early warning assessment of heavy metals in agricultural topsoil was realized by the ecological risk index method(I_(ER)).Through the test of the study area,it is concluded that the proposed method can accurately realize the ecological risk early warning of heavy metal pollution in agricultural topsoil.
