“…At the same time, the pollutants (HMs and sulfur) do have such an effect on the functional char acteristics of the microbial cenoses in the organic hori zon. Their effect in the upper mineral horizon lacks statistical significance, which confirms the fact that the industrial pollutants accumulate mainly in the organic soil horizons [3,17,35]. Thus, the level of the soil pollution and the degree of their technogenic transformation have a significant effect on the devel opment and functioning of the microbial cenoses in the forest tundra soils of the Norilsk industrial region.…”

“…Heavy metal compounds enter the soil with solid and liquid precipitation or plant debris and become involved in the natural cycle of matter. The organic soil component can accumulate large amounts of HMs due to its great adsorbing surface area and high buffer capacity [3,17,19,44]. Thus, the soils of the Norilsk industrial region are the main reservoir (sink) for the geochemical accumulation and biological deactiva tion of pollutants.…”

Assessment of the state of soil microbial cenoses in the forest-tundra zone under conditions of airborne industrial pollution

The quantitative and functional responses of soil microbial cenoses in the forest tundra zone to pollution have been studied in the area exposed to emissions from the Norilsk Mining and Metallurgical Works. The strongest structural and functional disturbances of the soil biota have been recorded on the plots with completely destroyed vegetation. A decrease in the content of microbial carbon and an elevated respira tion rate in the technogenically transformed soils provide evidence for the functioning of the microbial com munities under stress caused by the continuous input of aggressive pollutants. The degree of transformation and the contents of technogenic elements (Ni, Cu, Co, Pb, and S) in the organic horizons of the forest tun dra soils are the major factors affecting the development and functioning of the soil microbial cenoses.

“…In the most acidic soils of areas treated previously, it is appropriate to reintro duce lime, dolomite in the first place, in order to reduce acidity and immobilize HMs. [3], who revealed that the soils in the most degraded ecosystems of the local zone lose almost all of their organic matter and return to the initial soil forming material.…”

The soil of the technogenic barrens formed under the impact of long term air pollution around the Severonikel factory is acidic, depleted in nutrients, contaminated with heavy metals, and strongly eroded. Remediation by coating the topsoil with a fertile layer developed based on organic and mineral compounds is accompanied by decreasing the soil acidity and enrichment with carbon and nutrients (nitrogen, phosphorus, potassium, calcium, magnesium, manganese, and zinc). However, under the existing operational conditions, the surface layers of most treated soils accumulate nickel and, especially, copper. The efficiency of remedia tion depends on the composition and thickness of the constructed layer, as well as the related measures, which should be supplemented by repeated liming.

“…Destruction of the upper soil layers dramatically affects the local climate, which becomes evident in the increasing wind velocity, deeper frost penetration in winter, earlier thaws in spring, earlier summer droughts, and a more intensive heat penetration during the summer (Kozlov et al 2006). The lack of forest leaf litter (a storage of heavy metals), fresh leaf and plant shedding, combined with mineralization of the earlier accumulated organic matter, causes the soil to degrade and fail to provide mineral nutrition for the plants, leading to the loss of the entire vegetation cover (Kozlov et al 2006) and the soil horizon (Kashulina et al 2010).…”

Background:This work has explored the possibility of applying mining waste-based ameliorants for the remediation of soil that has been transformed by copper-nickel smelter emissions by means of forming artificial phytocenosis. Objective:The aim of our work was to propose, develop and approbate a technique for the preservation of dumps polluted by heavy metals and prevention of their erosion by creating dense grass covers with the use of wastes from mining and processing enterprises to form a supporting substrate for herbaceous plants. Methods:The vegetative cover was cultivated on a supporting medium, consisting of mining waste, with a hydroponic vermiculite substrate and a mix of graminaceous plant seeds, indigenous to the study area and resistant to heavy metal pollution. The mining wastes, used in the experiment, contained acid-neutralizing minerals such as calcium and magnesium carbonate and hydrous magnesium silicate. Results:It is shown that, due to a large pool of Ca and Mg, these mineral substrates are alkaline (pH 8.4 -9.2) and can perform successfully in optimizing of edaphic conditions for the plant communities grown on industrial barrens. In a pilot experiment without a proposed supporting medium, the plants did not form a stable grass cover and had died out by the beginning of the third growing season, whereas the experimental plots with a proposed supporting medium (waste-based substrate) developed a high-quality grass cover by the end of second vegetation seasons. Conclusion:The resulting plant communities grown on a proposed supportive medium is find to be resistant to aerotechnogenic pollutants and capable of independent survival, representing the initial stage of progressive succession in the presence of on-going pollution.
