土壤酶活性评价镉锌铅复合污染的可行性研究

Possibility of enzyme activities as indicators of assessing soil compound contamination with cadmium，zinc and lead

摘要: 模拟试验研究表明在Cd、Zn、Pb复合污染处理土壤中，过氧化氢酶、脲酶活性与碱性磷酸酶或转化酶活性可构成综合评价体系，反映土壤Cd、Zn、Pb污染含量以及土壤Cd-Zn、Zn-Pb复合污染效应，用其评价土壤Cd、Zn、Pb复合污染具有一定可行性。

Abstract: The simulated test shows that the activities of cat alase，urease and alkaline phosphatase or invertase can reflect the contaminating levels of Cd，Zn，Pb and the effects of Cd-Zn or Zn-Pb interaction in the soil treated with Cd，Zn and Pb.It is possible that these enzyme activities can be used as a comprehensive system to assess the compound contaminating levels of Cd，Zn and Pb in the soil.
