Abstract—The paper deals with the data on concentrations of heavy metals in sediments of wastewater of large
cities in the southeastern part of the Moscow region, and in soils, surface water, snow cover, and vegetables
grown in the Oka River floodplain. The conclusion is drawn that the most intense environmental pollution is
related to the operation of the Kashira State Regional Electric Power Station (SREPS). Vanadium, chromium,
nickel, copper, and zinc are emitted into the environment from chimneys of the Kashira SREPS, accumulate in
soils in topographic lows, and partially infiltrate vegetable products, as yet remaining below toxic levels. The
necessity for more comprehensive study of environmental pollution in the southeastern part of the Moscow
region and environmental protection measures is substantiated.
