“…Most of the Kuznetsk Basin coal is mined in the Kemerovo, Leninsk-Kuznetsk, Prokopyevsk, Mezhdurechensk, Kiselevsk and Belovo disctricts (Manakov et al, 2018). Coal mining, in particular open-pit coal mining, enrichment, and storage of coal, as well as coal waste disposal, leads to depletion of fertile soils and an increase in the toxicological indicators of soil (Drozdova et al, 2021;Ismagilov et al, 2018). When developing coal heaps, the fertile soil layer is removed, and mine soils become exposed.…”

Due to the large amount of pollution at coal spoil heaps, soil reclamation is slow and requires development and use of microbial preparations, selected based on assessments of the biochemical parameters of soil and the extent of its contamination. The material for this study was mine soils sampled in three different zones (Ka, Kb, Kc) of the Korchakol coal spoil heap. The studied sanitary and chemical indicators did not exceed the approximate permissible concentrations (APC) / maximum allowable concentrations (MAC), except for oil products (in the Ka, Kb, Kc zones, the excess averaged 2.2, 1.4, 1.2 times, respectively). The study found a direct correlation between the zinc content and the enzymatic activity of polyphenol oxidase, the level of Ni and peroxidase, as well as an inverse correlation between the As and Cu concentrations with invertase and nitrite reductase, respectively. The index of bacteria of the Escherichia coli group (coliform bacteria) in different zones exceeded the standard values by 61 and 171 times. Even though the sanitary indicators studied do not exceed permissible levels, they can slow down growth and development of plants. Thus, successful reclamation of mine soils requires introduction of biological preparations based on microorganisms that biotransform heavy metals and rhizobacteria.

Diesel vehicles are responsible for the emission of not only soot and NОx to the environment, but also various organic and inorganic toxic compounds. The review provides a detailed discussion of the place of oxidation catalyst in the modern system for purification of exhaust gases from diesel engines, the ways to improve and optimize the oxidation catalysts intended for the neutralization of carbon monoxide and hydrocarbons according to the accepted standards, and the methods for decreasing the content of Pt group metals in the indicated catalytic systems.
