Microbiological and biochemical indicators of the State of Karelian soils exposed to aerotechnogenic pollution

The data on the microbial communities and biochemical properties of forest soils obtained in the course of long-term studies in the region of the Kostomuksha ore mining and processing enterprise are presented. The changes in the parameters investigated caused by the anthropogenic impact were revealed. It was concluded that the microbial-biochemical characteristics may be used as an indicator of the state of soils exposed to aerial pollution.
