Abstract
The paper presents data on radionuclide activity in cryoconites of Elbrus Mountain glaciers and periglacial soils. The study was conducted on the glaciers of the Elbrus Mountain—Maly Azau, Garabashi, Terskol and in the area of Prielbrusye, Kabardino-Balkarian Republic, Russia. Specific activity of natural radionuclides (K-40, U-235, U-238, Th-232) and cosmogenic Be-7 and technogenically orginated Cs-137 was determined. It was shown that activity of all investigated natural radionuclides in the samples taken on the studied glaciers is higher on Maly Azau, and cosmogenic Be-7 and technogenic Cs-137 at Garabashi. Revealed that cryoconites in the Arctic and Transcaucasia comparable to our data, and the Alpine glaciers have a higher specific activity natural radionuclides. The activity of cosmogenic radionuclide Be-7 in cryoconites of Elbrus glaciers was below the world average and amounted to 12.7–60 Bq/kg. In contrast to cryoconites from glaciers of other regions of the Earth, where very high concentrations of Cs-137 were found, in samples of cryoconites from glaciers studied by us this radionuclide showed relatively low values 0.44–68.2 Bq/kg. The data obtained in the study supplement the information on the geographical features of radioactive contamination of cryoconites of glaciers and periglacial soils mountainous areas.
期刊介绍:
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
