Abstract
Studies were performed concerning the features of soil ecological, microbiological and biochemical properties under influenced by the emissions of aluminum plants in Siberia. It has been found that the anthropogenically transformed soils of sub-taiga influenced by water-soluble fluoride species (10–20 MPC) cause the greatest inhibition of actinomycetes and chemoorganotrophic asporogenous bacteria. The steppe chernozem under the influence of fluorine (1–4 MPC) demonstrates a decrease in the level of biochemical activity.
