Abstract

An important environmental problem of the present is the accumulation of toxic metals in soils. Based on the analyzed literary sources, it is shown that the most contaminated territories of our country are urbanized areas of the central and south-eastern regions. Among the pollutants of metals, the most common and toxic are lead, zinc, copper, cadmium, nickel and aluminum. Mobility and bioavailability of heavy metals and aluminum is directly proportional to the acidity of the soil. Taking into account the potential hazard of toxic metals for living organisms, the urgent task of scientists is to assess the biological risk of these substances. The article analyzes the accumulation of soils adjacent to the highway Kiev-Odessa, lead compounds (Pb) and nickel (Ni) at different distances from the source of pollution.
