Abstract:The relationship between microbial biomass and enzyme activities under heavy metal pollution had attracted much attention in ecology.
Enzyme activity The urease activity was determined by the method of Tabatabai and Bremner, expressed as mg NH4-N kg_1 h_1[10].
The Urease activity in the heavy metal-amended samples and control with different metal concentrations is given in Fig. 1.
