“…Dangerous heavy metal elements are divided into the following 3 groups according to the intergovernmental standard GOST 17.4.1.02-83 [4] (Table 1): It is important to study the anthropogenic effects of deposits on the environment by species, in which the study of the effects of heavy metals [5] as well as the study of the anthropogenic effects at different times concern the dynamics of heavy metal accumulation [8]. Urban soils are mainly contaminated with Pb, Zn, Ni, Mn, Ba, As, Hg, Mo, Cr, Sr, V, Ni, Cr, Co, Cu, F, Al, Li, Be, Ag , Ti, Cd, Se, Sn, Tl, Bi, Na, K, S, Cl, petroleum products etc, as a result of the increase in the number of industrial enterprises over the years [6]. Soil and vegetation cover around metallurgical plants are primarily damaged, with increased aerotechnogenic pollutants not only affecting the upper organic part of the soil, but also the lower mineral layers [7].…”

The article describes the man-made degradation of irrigated soils, resulting from chemical pollution, changes in soil chemistry, and heavy metal pollution during thermal power plant operation. According to the results, the pH value of the soil fell from 7.2 to 6.1 as a result of man-made degradation, ie the acidic environment increased as a result of pollution. Also, some heavy metals, including As - increased by 4.2 times, Cr - by 16 times, Ni - by 2.5 times, Rb - by 3.7 times, Zn - by 4.8 times. Changes in soil environment and soil ecological status have resulted in deterioration in fertility rates and negatively impacted crop yields and quality.

: For the first time, polycyclic aromatic hydrocarbons (PAH) contamination of the soil cover of Ulan-Ude, the capital of the Republic of Buryatia, was studied. The content of 16 individual polyarenes was analyzed in the upper horizon of background chestnut and urban soils, sampled during soil and geochemical survey in July–August 2022. The average concentration of total PAHs in the soil cover of Ulan-Ude was 735 ng/g, which was 8 times as much as the concentration in the background soils (87 ng/g). The PAH amount in the soil of various functional zones decrease in the following order: railway transport > motor traffic > industrial > one-story residential > multi-story residential > recreational. At the same time, the amount of PAHs in the railway transport zone was 2.6–5.2 times higher than in other functional zones, which indicates that railway transport is the most powerful source of PAHs in the city. Contamination of soils with polyarenes in all functional zones is determined primarily by medium- (46%) and high-molecular-weight (41%) compounds. Among PAHs with low molecular weight, phenanthrene prevailed (9% of the total PAHs), but medium-molecular-weight fluoranthene (18%) and pyrene (13%) showed higher share; high-molecular-weight compounds dominated by benzo(ghi)perylene (12%), benzo(b)fluoranthene (10%), indeno(1,2,3-cd)pyrene (8%) and benzo(a)pyrene (6%). The total amount of 16 PAHs in the soil cover of the city varied within the range of 17–9 540 ng/g. The highest levels of pollution (3 226–9 540 ng/g) were recorded at 9 sampling points (4% of the city), which form the most contrasting local PAH anomalies. In more than half of the territory of Ulan-Ude, the total amount of PAHs did not exceed 500 ng/g. The indicator ratios of individual PAHs made it possible to determine the dominant types of sources, which include railway transport and coal combustion. The contribution to the environmental hazard of soil contamination with PAHs in Ulan-Ude was mainly made by benzo(a)pyrene (64%) and, to a lesser extent, by benzo(b)fluoranthene (9.6%), indeno(1,2,3-cd)pyrene (7.2%), dibenzo(ah)anthracene (6.5%) and benzo(a)anthracene (6.1%).
