外源Cd对中国不同类型土壤酶活性的影响
Response of Soil Enzyme Activity in Different Type of Soils to Cadmium Exposure in China
摘要
Abstract
[Objective]The objective of this study was to clarify the soil enzyme of different type soils affected by Cd under soil environmental quality standards in China, to explore the relationship between soil enzyme and Cd, and discuss the feasibility of soil enzyme acted as an indicator of soil Cd pollution.[Method]The influences of Cd addition to soil enzyme activities in different types of soils were studied by a traditional pot incubation experiment with three Cd concentrations.[Result]The results indicated that the soil acid phosphatase and catalase activity were not sensitive to Cd, Cd could remarkably inhibit soil FDA hydrolase and dehydrogenase activity, but activated the urease and alkaline phosphatase activity. Under the soil environmental quality standards for agricultural soils, the average inhibition rate of soil FDA hydrolase and dehydrogenase was 34.03%and 31.14%respectively. Soil enzymes, soil enzymes-physicochemical properties-Cd information system showed significant positive correlations with soil total enzymatic activities, which suggested they may indicate the Cd contamination.[Conclusion]Soil FDA hydrolase, dehydrogenase and soil total enzymatic activities are sensitive to soil Cd, which can be used as a assisted monitoring indicator. The relationship between soil enzymes and Cd is influenced by many factors such as enzyme types and soil properties, and soil organic matter and pH play a matter role.关键词
