摘要
本文通过对污灌土壤中铜和锌总量和形态含量及其分布的研究,揭示了铜和锌总量和诸形态含量的微域分异规律,从而为污灌区农田土壤重金属污染的评价提出了新的依据。
The total amounts and its speciation contents of copper and zinc and its distribution in sewage irrigatedsoilwerestudied.it is found that the total amounts and the speciation contents of copper and zinc have a small regional difference. The conclusions show that cation specition and regional difference are new factors in the assessment of heavy metals pollution in sewage irrigated soil.
