“…In the territory of the Central Caucasus, there is one of the largest non-ferrous metallurgy enterprises in Russia-the Electrozinc plant (Vladikavkaz city). A metallurgical enterprise is a source of catastrophic pollution of the environment with Pb, exceeding the regional Clarks of Pb in the soils [61,62] by dozens of times [63]. As could be observed in the results of the present study, such Pb content causes a disruption in all the groups of the soil ecosystem functions (Table 4), which means a catastrophic disruption of the soil functioning [22,34,43].…”

Lead (Pb) is one of the most hazardous heavy-metal pollutants in the environment. However, the resistance of different soils and ecosystems to Pb pollution varies greatly. In the present study, the comparative assessment of the resistance to Pb contamination in the forest, forest-steppe, steppe, and mountain-meadow soils of the Central Ciscaucasia and the Caucasus regions was conducted. There were 10 types and subtypes of objects from the forest, forest-steppe, steppe, and mountain-meadow soils which were selected for this study. The laboratory modeling of the effect of chemical soil contamination with lead (II) oxide (PbO) at different concentrations, 100, 1000, and 10,000 mg/kg, were introduced into the soil to check the microbiological, biochemical, and phytotoxic properties of the soil after 30 days of incubation. Soil resistance to Pb stress was assessed by the degree of the decrease in the most sensitive and informative biological indicators of the soil condition. It has been found that the forest-steppe and steppe soils showed a greater resistance than that of the forest and mountain-meadow soils. The regional maximum permissible concentration (rMPC) of Pb was developed for the first time, according to the degree of violation of the ecosystem functions of the soils. The forecast maps were developed for the deterioration of the soil condition during the Pb contamination at variable concentrations in the Central Ciscaucasia and the Caucasus regions.

“…The methodological basis for using the proposed indicators is the identification of landscape and geochemical features of the site under consideration with its regional analogues and comparison with the calculated indicators of its ecological state with normalised characteristics. In case of parameters deviation from the background value, further procedure and adjustment of the land plot value depend on the degree of deviation from the norm [16]. For this purpose, it is proposed to use three levels of abnormality, determined by means of the variation-statistical processing of the results of sampling and cartographic modelling.…”

The article presents the results of the analysis of the main trends in the ecological and geochemical transformation of the environment of Southern Russia. The research on revealing the regularities of migration and distribution of elements in soils of landscapes testifies to the necessity of changing the basis of management. This includes introduction of ecosystem principles of management of nature use and environmental quality, timely adjustment of economic mechanisms and resource cycles. The methodology of the ecosystem ecological rationing of chemical elements in soils for optimisation of differentiated land use management has been developed. The system of measures to ensure environmental safety in the region is proposed. It includes identification of pollution and assessment of sources of environmental hazards, maintenance of environmental passports of land plots, measures to protect the environment in the process of economic activity, measures to prevent and eliminate natural and man-made emergencies associated with environmental pollution.

“…Cr, Cu, Ni, and Pb have been chosen as pollutants, since the soils in southern Russia are largely polluted by these HMs (D'yachenko & Matasova 2016). Moreover, the HMs selected are interesting for comparison their maximum permissible concentration (MPC) (100 mg/kg of soil).…”

This paper provides an assessment of the resistance of Taman chernozems to contamination with heavy metals (Cr, Cu, Ni, Pb) and oil by biological parameters. As a rule, upon contamination of the Taman chernozems, a significant reduction was observed in the total bacterial count, activity of catalase and dehydrogenase, cellulolytic activity, abundance of the Azotobacter genus bacteria and in the radish germination intensity. The extent of the deterioration in biological properties was determined by two factors: the chemical nature of the metal and its amount in the soil. As a rule, a direct relationship was observed between the concentration of the pollutant and the degree of deterioration of the soil properties in this study. The metals studied had shown different ecotoxicity with respect to the chernozems of Taman: Cr > Cu ≥ Ni = Pb Regional norms for the maximum allowable content of Cr, Cu, Ni, Pb, and oil in the Taman southern chernozems based on a disturbance of the ecological functions of soils were proposed.
