DYNAMICS OF ISOTOPES 210PB AND 210PO IN NATURAL MEADOW ECOSYSTEMS AND AGROPHYTOCENOSES WITH THE REGULAR APPLICATION OF PHOSPHORUS FERTILIZERS
Abstract
Distribution of 210Pb and 210Po radionuclides in the soils of natural meadow ecosystems and in the arable soil horizons of agroecosystems of the south-eastern region of the Republic of Belarus has been investigated. The difference between the radionuclides content in the upper 0–5-cm layers of organic horizons and in the underlying layers of soils of natural meadow ecosystems has been revealed. The distribution of 210Pb and 210Po along the vertical profiles of meadow soils allows assuming that the intake of radionuclides in to soil cover is mainly due to aerosol deposition from atmosphere and their biogenic accumulation in the upper part of the organic horizons. It was shown that in arable horizon of agricultural soils, which are regularly fertilized, content of 210Pb and 210Po depends linearly on concentration of mobile phosphorus. Reducing the acidity of soil medium promotes to the reduction of 210Pb and 210Po bioavailability and their accumulation in vegetative production. The transfer factors of 210Pb and 210Po for vegetables, which are widespread on the territory of Belarus, were determined. It was established that the transfer factors of 210Pb and 210Po are increased in the next order: carrot – potato – cabbage and those for 210Po were twice as for 210Pb.
