Heavy metals in system "atmospheric air - Water - soil - Crop products"

The article presents results of heavy metals (HMs) monitoring in system "atmospheric air - water - soil - crop production" on three territories with different levels of pollution where agricultural fields and livestock complexes are situated. Highly hazardous Cd, Pb, Zn and moderately hazardous Cu are priority HMs for Ryazan region. A direct relationship has been established between the concentration of heavy metals on territories of different ecological conditions, as evidenced by the high concentration ratios of toxicants in environmental objects. The total pollution of facilities in JSC Avangard in Ryazan district, located within the regional center of Ryazan, is 13 % and 33 % higher in comparison with other two farms, which is explained by the entry of HMs into the environment with emissions and discharges of enterprises, their sedimentation into other environments. © 2022 Institute of Physics Publishing.
