Semenova I.N., Ilbulova G.R., Zulkarnaev A.B., Suyundukov Ya.T. EFFECTS OF ZEOLITES ON ENZYMATIC ACTIVITY IN ORDINARY CHERNOZEM IN CASE OF LEAD CONTAMINATIONIn study of enzymatic activity of soil, polluted with Pb, it was found that when the lead content was up to 10 MACs (maximum allowable concentrations), urease activity in nonfertilized soil was reduced to 50%, proteolytic activity — to 25%, and cellulolytic аctivity — to 36% from activity in uncontaminated soil. In the presence of zeolites and organic fertilizers, this effect was less pronounced. Key words: enzymatic activity of soil, zeolites.
