摘要

The influence of two lead salts on the soil enzymatic activity dynamics (urease, dehydrogenase, the total hydrolase activity, acidic phosphatase, and peroxidase), with lead ion concentrations of 10, 100, 300, 500, and 1000 mg/kg, was assessed in a 21-day-long model experiment. A reliable inhibitory effect of lead nitrate applied at doses of 500 and 1 000 mg (Pb2+)/kg on the total activity of hydrolases, dehydrogenase, and peroxidase has been identified, while lead acetate mostly caused a stimulating effect. Based on the data obtained, the diagnostic indicators have been ranked by the reduction of their sensitivity to lead nitrate pollution in the following order: total activity of hydrolases > peroxidase > dehydrogenase > urease similar to acidic phosphatase.
