Abstract
The results of studies of three sites of agrocenoses are presented: wheat (seed cereals), soybeans (legumes) and legume-cereal (rumpgoatskin) perennial grass mixtures to identify the peculiarities of the transition of stable and radioactive pollutants (including substances of hazard classes 1 and 2 and 137Cs) in the system "agro-chernozems – agricultural plants" with soil testing and quality control of aerial and underground plant phytomass. In this radioactively contaminated area, the elemental composition of wheat, soybean, rump and goatskin does not differ from the composition of the corresponding species in the background. Legumes have an increased need for alkaline earth metals (Ca, Mg, Sr) and also contain more Ni and Mn, cereals – in Si. Within the studied part of Plavsky radioactive spot, the quality of agricultural products meets the relevant standards for the content of heavy metals and 137Cs.
