Abstract

Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission HF were studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi was revealed, along with a decrease in the enzymatic and respiratory activity of polluted soil with the relative increase in the fraction of soporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na2SO3 microbiological norm-fixing for technogenic soil ecosystems was carried out.
