ECOLOGICAL PROBLEMS OF AGRICULTURAL LANDSCAPES OF RYAZAN REGION

Abstract

The leading sources of anthropogenic pollutants in Ryazan Region are emissions from industrial enterprises. The main route of heavy metals deposition is via atmospheric precipitation. Dust precipitations are enriched in Zn, Pb, Cd, whereas aqueous precipitations, in Cu. The first maximum of the accumulation of metal, mainly Cu, Mn, Zn, Ni, Pb, Cd and Co, is observed in all types of soils of the Ryazan region. The second maximum (Zn, Cu, Pb, Co, and Ni) is featured by the illuvial horizons on the geochemical barrier. Sn and Mo are almost evenly distributed across the soil profile. Based on the soil survey in Ryazan Region, its landscapes were ranked according to the gross content of heavy metals. The resulting maps characterize the current and forecasted levels of soil pollution with heavy metals in Ryazan Region.
