Ecology

Biochemical activity analysis, i.e., catalase and dehydrogenase enzyme activities analysis was used as control, i.e., at effectiveness assessment of reclamation process of mechanically disturbed soils in the impacted ecosystems of a gas production company in the Taz peninsula (The Yamalo-Nenets autonomous district, north of West Siberia, Russia). Regeneration of a vegetation cover as self-restoration of the disturbed soils was diagnosed by the catalase activity analysis, and efficiency of peat based reclamation of disturbed soils was diagnosed by the dehydrogenase activity analysis.
