摘要
为了研究黄河口国家公园湿地土壤污染状况和生态风险,沿黄河故道东营段、黄河入海口以及沿海处共设20个采样点进行土壤采集,对铅、镉、铬、铜、锌、镍、汞、砷8种重金属含量进行检测,并利用综合污染指数法、地累积指数法和潜在生态风险指数法进行土壤污染评价。结果表明:研究区铅、镉、铬、铜、锌、镍、汞、砷元素的质量比分别为16.4、0.11、57.3、14.0、46.9、20.0、0.014、7.71 mg/kg,均符合农用地土壤污染风险管控标准要求;研究区土壤综合污染指数为0.57,地累积指数为-0.23,潜在生态风险指数为65.54,表明研究区属于无污染土壤,存在轻微潜在生态风险。
To study the soil pollution status and ecological risk of the wetland in the Yellow River Estuary National Park,a total of 20 sampling points were set up along the Dongying section of the old Yellow River course,the mouth of the Yellow River and the coastal areas for soil collection,and the content of Pb,Cd,Cr,Cu,Zn,Ni,Hg and As were detected.Soil pollution was evaluated by comprehensive pollution index,ground accumulation index and potential ecological risk index.The results show that the mass ratios of Pb,Cd,Cr,Cu,Zn,Ni,Hg and As in the study area are 16.4,0.11,57.3,14.0,46.9,20.0,0.014,7.71 mg/kg respectively,which all meet the risk control standards for agricultural land soil pollution.The integrated soil contamination index of the study area is 0.57,the land accumulation index is-0.23,and the potential ecological risk index is 65.54,indicating that the study area is a non-polluted soil with a slight potential ecological risk.
