Amount of mobile toxicants in typical gray soils and irrigation water contained Kitab district, Uzbekistan
Abstract
At present, the pollution of all natural components, including soil and water resources, with various toxic elements has become an urgent problem. Of course, this requires scientific research to prevent problems and conduct continuous monitoring. The article presents studies conducted on typical irrigated sierozem soils located in the foothills, as well as irrigation waters, studied data on the accumulation of such elements as Lead, Cadmium, Cobalt, Copper, Nickel, Chromium and Zinc. Chromium, Copper, Lead, Nickel, Cadmium were according to the state of contamination of the elements detected in the soil, except for the elements cobalt and zinc. Irrigation water has the following increasing sequence: Nickel, Cadmium, Cobalt, Copper, Lead. Chromium and zinc elements were found to be lower than the maximum permissible concentration in irrigation water.
