The Effect of Industrial Aerial Pollution on the Composition of Soil Solutions in Podzols

摘要

The composition or soil solutions is a sensitive indicator of the technogenic transformation of pod-zols of the Kola Peninsula under the impact of aerial pollution. The soil solutions have been obtained using Rhizon vacuum samplers. A sharp rise in the concentrations of heavy metals and sulfates is registered in the solutions from polluted soils. The leaching of organic substances, potassium, sodium, calcium, magnesium, manganese, and zinc from the litter horizons of polluted soils considerably increases. The ratios between the element concentrations in solutions from the litter horizons to those from the illuvial horizons become narrower, which suggests that the litter has partly lost its barrier function.
