Ecological-microbiological and biochemical characteristics of soil cover under aerotechnogenic contamination
An analysis is made of experimental data obtained from studying the ecological-microbiological and biochemical characteristics of soil cover in the influence area of emissions from Siberias aluminum smelters. It is found that actinomyces and chemoorganotrophic non-spore-forming eubacteria undergo the most severe inhibition under the influence of the water-soluble form of fluorine (10-20 MPC in the 0-10 cm layer) in the anthropogenically transformed sod forest soil of the subtaiga zone. A decline in the level of biochemical activity is observed in humus-deficient chernozem f the steppe to be caused by fluorine (1-4 MPC in the 0-10 cm layer).
