ESTIMATION OF TOXIC EFFECT OF HEAVY METALS ON SOIL BIOTA

It is well known that heavy metals (HM) are classified as toxic and carcinogenic pollutants that to cause the suppression of the number and the biological activity of the soil microflora. The authors of the review article, based on the data of other researchers and own data, consider that it necessary to develop indicators of biological monitoring of urban soils, reacting to the presence of heavy metals. The study of microbiocenoses of Almaty city's soils led to the definition of the degree of toxicity of urban soils, selection of dominant microbial stenobionts (both sensitive and resistant to HM). It was realization of methodological approaches of bioindication for microbial control of Almaty city soil pollution. The implementation was carried out the methodological approaches of bioindication for microbial control of Almaty city soil pollution.
