Heavy metals availability in soils of urban territories common areas (parks and squares) on the right bank of Krasnoyarsk

The article analyzes the availability of heavy metals (nickel, copper, cadmium, chromium, zinc, lead, cobalt, iron, manganese) in the soils of urban territories in the parks and squares on the right bank of Krasnoyarsk. Increased emissions of harmful substances into the atmosphere by industrial enterprises and the increasing flow of traffic imposed by the adverse weather conditions (no wind) exacerbate the ecological situation in the city. The ecosystem of urban areas experiences tremendous stress and accumulation of harmful substances (heavy metals) in soil and plants exceeds the background values. The content of heavy metals in soils of parks and gardens of three administrative regions was set for Sverdlovsk, Kirov and Lenin regions, where the main industrial enterprises of the city are concentrated and which are also characterized by high vehicular flow. The quantity and survey of the species composition of woody vegetation and shrubs growing in the parks and squares were examined. The number and intensity of passing vehicles on the streets adjacent to the places of people’s recreation were determined. The soil samples for investigation on the content of heavy metals were selected from the upper soil horizons with the most common places for residents of the n'ght bank of Krasnoyarsk.
