S. N. Tarkhanov Тhе Content оf Sulfur and Heavy Metals in Soils and Needles оf Coniferous Stands under Aerotechnogenic Pollution in the Severnaya Dvina River Basin // Forest Science (Lesovedenie). 2011. No 3. С.26-33 . The sulfur and heavy metal (Zn, Сu, Cd, Рb, and Hg) contents were determined in the soil organic horizons and 1-, 2-, and 3-year-old needles of coniferous stands exposed to aerotechnogenic pollution in the Severnaya Dvinа River basin. А trend of the more intense sulfur accumulation in spruce needles going toward thermal power stations and paper mills is observed. However, nо distinct relations between the heavy metal contents in the organic soil horizons and spruce needles and the distance from the local pollution sources were revealed. Sulfur, heavy metals, coniferous stands, soil, spruce needles, airotechnogenic pollution, Severnaya Dvinа River. . |
