【 摘 要 】

The article presents a comparative analysis of the impact of the introduction of different doses of copper and cadmium on the activity of redox enzymes of urbanozem, collected from different territories of Ufa. The studies established the inverse relationship of the activity of catalase and polyphenol oxidase, and the direct one of the activity of peroxidase that depends on the doses of heavy metals, that allows to recommend their use as bioindicator of pollution of urbanozem with these metals. The reaction of the studied enzymes on the introduction of heavy metals is an indicator of their toxicity to living things at the molecular level. Comparative analysis of the impact of cadmium and copper in different doses on the activity of soil enzymes did not reveal a uniform regularity. Each of the metals showed their toxicity in different ways depending on the duration of their impact.
