    The Investigation and Evaluation of Heavy Metal Pollution in Wastewater Irrigated Soils and Vegetables in the Suburb of Foshan

      摘要
    • 摘要: 对佛山市郊5个镇污灌菜地灌溉水、土壤和蔬菜的重金属污染状况进行了调查分析.结果表明,污灌菜地土壤重金属污染比较严重,其主要污染物是Hg和Cd,超标率分别是93.88%和12.24%,有77.5%的土壤综合污染指数大于1;所产叶菜除Hg含量全部符合无公害蔬菜标准外,Cr、Pb、Cd均有不同程度超标,超标率分别是28.57%、14.29%和21.43%.

       

      Abstract: The heavy metals pollution on soils and vegetables for some sewage-irrigated vegetable bases in the suburb of Foshan were investigated.The results showed that the heavy metal contamination in soils of the suburb of Foshan was serious.The contents of Hg and Cd exceeded 93.88% and 12.24% respectively in the collected soil samples,comparing to the Grade II limited values of the national soil environment quality standard.The comprehensive pollution indexes of 77.5% of the soils were greater than 1.The leaf vege...
