Abstract

This article presents the results of a study of soil properties and composition, as well as of the species diversity of plant coenoses in areas at different distances from the enterprises of the Kola Mining and Metallurgical Company (MMC) in the city of Monchegorsk and in the urban settlement of Nickel. Soils of the impacted areas are characterized by the maximal concentrations of Ni, Cu, and Co. The ratios of mobile Cu and Ni to Ca and Mg in the organic topsoil horizons indicate their phytotoxicity. Morphological features of plants in such areas reflect acid damage, their species diversity being minimal. It is suggested that high Ni, Cu, Co, and Cr content in soil is a result not only of technogenic contamination, but also of natural geochemical anomalies above the ore deposits, as the MMC enterprises are located in their vicinity. Technogenic geochemical anomalies are formed near the MMC enterprises; Ni, Cu, Co, and Cr content in soil and their mobility decrease and plant species diversity becomes greater with distance from the enterprises. Weak and ambiguous correlations are revealed between plant biodiversity and soil properties, the correlation being statistically significant for Cu and Ni content in soil.
