Состояние комплексов почвенных микроскопических грибов в зоне воздействия аэротехногенных выбросов Кандалакшского алюминиевого завода

Abstract

It has been performed comparative analysis of changes in the soil properties and in the soil mycobiota that had occurred over the last 10 years on the gradient of airborne pollution emissions Kandalaksha aluminum plant in connection with reduction their volume. The concentration of priority pollutant fluorine compounds in atmospheric precipitation and in the soil organic horizons was a significantly lower in 2011 compared to 2001 year in the impact plant zone. At present, the species composition of the microscopic fungi complexes represented by 31 species. 60 % of the selected species are found in both the study period. There was decreased acidity of litter almost 2 pH units near the plant at a distance of 2 km. Plant emissions still caused inhibition of fungal biota as the method of planting and the method of direct calculation. Over the 10-year period there was a significant change of the dominant species.
