“…19,47 Thus, they are marked by the continuous freezing of environmental components, at times for 5 months, which might explain their lowered capacity for self-purification from the anthropogenic effect. 8 The samples were taken from the urban soils of diversely functioning zones: industrial, residential, natural-recreation, and soils from town suburbs.…”

The study was conducted in 2 urbanized areas of the Baikal region of Russia. These are the cities of Shelekhov and Tayshet with their suburbs. Aluminum production has been carried out in Shelekhov for over 60 years and in Tayshet for 5 years. The purpose of the study was to determine the pollution of urban soils with toxic elements—Al, F, Be, Li, as well as Cr, Ni, Pb, and so on under the influence of industrial enterprises (aluminum and cable plants, thermal power plants). Also, the purpose of the research was to determine the effect of increased fluorite (F) in the environment on children’s health. Pure aluminum is used much less frequently than in alloys. The addition of various elements (Be, B, Li, Fe, Si, Mg, Mn, Zr, Ag, Pb, Cu, Ni, and others) increases the hardness, density, thermal conductivity, and other properties of the alloys. The area of high F content in urban soil is 15 times higher than the regional context. The maximum content of Na, Be, and Al is 2 to 4 times higher than the regional background. An increased Li content is marked only near aluminum smelters. The F content in urine samples from children living in areas with long-term pollution exposure (Shelekhov) is 1.5 to 2 times higher than in the group of children with a short exposure period (Tayshet).

This experimental work was done before the stopping the Baikalsk Paper and Pulp Mill. As the informative criteria for the present state of anthropogenic soils used in this study the degree of their biochemical activity and the acid-alkaline conditions which belong to integral indicators was taken. The basic technique for carrying out mass analyses of biochemical activity of soils characterizing the territory of the city of Baikalsk was the rapid analysis method suggested by T. V. Aristovskaya and M. V. Chugunova. The study revealed a high level of soil activity in all functional zones of the city. The acid-alkaline contents were determined for the soils under investigation, which showed a wide range of values (from 6,7 to 8,5 рН). On the basis of the data obtained and point measurements in the geoinformation environment the IDW Nearest Neighbors method was used to construct isopleth maps. A trend for a weak but positive correlation was revealed between the acid-alkaline conditions and soil biochemical activity. All the findings provide a basis for further monitoring the post-technogenic recovery of the city’s soil ecological status in the setting of Southern Baikalia.

Results from studying urbanized territories highly depend on approaches and methods of interpreting data obtained in the course of investigations. A case study was made in the industrial city of Usolye-Sibirskoe (Irkutsk oblast, RF) to investigate and map the current ecological-and-biochemical status of soil cover affected by urbanization and technogenesis. T. V. Aristovskaya’s and M. V. Chugunova’s rapid method was used to reveal high indicators of the level of alkaline-acid conditions and biochemical activity of urban soils. The mapping enabled identification of the local features of the urban territory. A considerable part of it is occupied by soils with weak alkaline pH index (7.3–8.0). In absolute values, it is 6083.3 ha, or 77.2 %. The study determined a high and very high level of the soil biochemical activity. They occupy a large area of 6079.2 ha, i.e. 76 % of the city. A substantial increase in soil biochemical activity can lead to loss of a biogenous element, nitrogen, and this cannot be regarded as a positive phenomenon. Experimental data on the SBA – рН system for the residential zone of the city made it possible to determine a close correlation between them to be statistically significant.
