The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in order to study the temporal processes of retention and release within the soil. The mineral layers were strongly acidified by the contaminated precipitation. Forest floor layers demonstrated a high capacity to retain input Ni and Cu under all conditions. Mineral layers accumulated some Cu, but released Ni. In general, Ni leached through the soil faster than Cu. Since metals are strongly retained in the forest floor layer, even after reduction or cessation of inputs there may be a significant long–term risk of their leaching to deeper soil and groundwater. This risk cannot be ameliorated without remediative intervention.

Parameters of heavy metals (accumulated in objects with past environmental damage, e.g. unauthorized dumps of municipal wastes, sludge deposits from treatment facilities, and reclaimed quarries) distribution in soddy podzolic soils’ agrocenosis have been studied in this paper. Negative changes of soils’ properties for the lands, periodically experiencing contamination from the objects with past environmental damage have been characterized. In the conditions of minimization of mechanical impact on soil, a negative trend in soil properties changing on the adjacent to objects with past environmental damage lands at preservation of uncontaminated automorphic analogs has been tracked. Agrocenosis degradation indicators are substantially defined by past ecological damage objects’ specifics.

Heavy metals and other trace elements that are not subject to degradation are among the priority pollutants. Significant amounts of heavy metals and related elements with variable valence are deposited on the soil surface as part of aerosols. Accumulating in the soil, they are very slowly removed from it, only changing the level of content or the state during migration, turning the soil over time into a source of secondary pollution. In this regard, an extremely urgent task is to assess the territory, especially such a highly developed and densely populated area as the Moscow Region, in terms of its protective potential to heavy metal pollution. The paper proposes and tested an algorithm for the cartographic assessment of the protective potential of the soil and vegetation cover of the region using GIS analysis methods based on the database “Digital medium-scale soil map of the Moscow region” and a vector map of forest cover. The formula used for calculations includes data on the soil texture, the content of organic matter in soil, the position of the soil in the landscape and the degree of forest cover of the territory. According to the proposed approach, in the Moscow region, the soil cover, taking into account the forest cover, forms 4 groups according to the level of protective potential for contamination with heavy metals and metalloids. The maximum estimate was obtained for noneroded sod-podzolic soils of medium or fine texture, gray forest soils, chernozems and peat bog soils under forest vegetation (17 % of the area). Unerroded soddy-podzolic soils of varying degrees of podzolization and gleying (45 %) received an average rating. Even lower is the protective potential of 22 % of the territory represented by eroded gray forest soils, various sod-podzolic, alluvial and peat bog soils. This group is the most heterogeneous in terms of soil texture, organic matter content and degree of forest cover. The group with a minimum protective potential included eroded soils, soils of gully-girder complexes, sod-podzolic soils of coarst texture, as well as alluvial peat and peaty soils (about 16 %).

The article presents the content determining results of heavy metals and arsenic in sod-podzolic soils of the school grounds in Vladimir, Vladimir region. According to the accumulation indicator, the accumulation intensity of heavy metals and arsenic in these areas has been determined, which is decreasing in the series of Pb→As→Cu→Zn→Ni. The calculation of the pollutants hazard coefficient showed that their MPC excess decreases in the series of As→Zn→Pb→Cu→Ni. The soil pollution level has been assessed for the school grounds and their ecological situation has been evaluated applying the cumulative indicator of soil pollution with heavy metals and soil pollution index. The values of the soil pollution cumulative indicator of school territories indicate dangerous and moderately dangerous contamination level of the studied soils, and the calculated values of the soil pollution index refer these soils to the category of “contaminated” soils, which poses potential risks for the schoolchildren health.

Heavy Metals In Soils

The article highlights the results of research on the content of heavy metals in sod-podzolic soils of oil-contaminated areas of Ivano-Frankivsk region. Contamination of soils with petroleum products causes severe ecological consequences for ecosystems. The aim of the research was to study the peculiarities of the accumulation of heavy metals in the soil, underground part and vegetative mass of sylphia perforated in the conditions of cultivation in oil-contaminated areas. The content of mobile forms of heavy metals in soils did not exceed the norms in all variants of the experiment. During the cultivation of Sylphia perfoliatum, it grew in a number: cadmium → nickel → cobalt → lead. The concentration of heavy metals in the soil was determined, which reflects the change in the content of the element in the test soil relative to the content of metals in the background soil. The coefficients of concentration of mobile forms of heavy metals in oil-contaminated soil for the cultivation of perforated sylphia for the application of fertilizers based on sewage sludge and compost based on them increased in a number: cobalt → lead → nickel → cadmium. Peculiarities of heavy metals accumulation in the vegetative mass of perforated sylphia have been established. Indices of intra-tissue heavy metal contamination of the root system of sylphia perforated with the introduction of sewage sludge increase in the following series: cadmium → nickel → lead → cobalt. The maximum indices of contamination of sylphia roots permeated with cadmium, nickel and cobalt are observed for the introduction into the soil of ERUs at a rate of 40 t / ha and N10P14K58, lead – for the application of compost at a rate of 30 t/ha and N30K55. The lowest indices of intratissue contamination with heavy metals of the roots of sylphia perfoliatum were noted for the application of fertilizer N60P60K60.
