摘要
为了解广东佛山金陡涌河道底泥中重金属的污染状况,本研究采集了38个采样点的沉积物样品,并测定样品中重金属Cu、Zn、Pb、Cd、Cr、As与Ni的含量,同时运用地累积指数法与潜在生态风险指数法对金陡涌河道底泥中重金属的污染程度和生态风险进行评价。结果表明,金陡涌存在严重的金属富集,其中Cr、Cu、Ni、Cd、Zn均存在不同程度的富集,且Ni与Cd潜在生态风险大,应即时控制污染源头进行针对性治理。
In order to understand the pollution status of heavy metals in the sediments of the Jindouchong watercourse in Foshan,Guangdong,this study collects sediment samples from 38 sampling points,and measures the contents of heavy metals Cu,Zn,Pb,Cd,Cr,As and Ni in the samples,and uses the geoaccumulation index method and the potential ecological risk index method to evaluate the pollution degree and ecological risk of heavy metals in the sediments of the Jindouchong watercourse.The results show that there is serious metal enrichment in the Jindouchong,among which Cr,Cu,Ni,Cd and Zn are enriched to varying degrees,and Ni and Cd have great potential ecological risks,and the source of pollution should be immediately controlled for targeted treatment.
