CONTENT OF HEAVY METALS IN SOILS UNDER THE INFLUENCE OF UNAUTHORIZED DUMPS IN SURGUT
The article examines the influence of unauthorized dumps on the accumulation of heavy metals (lead, copper, zinc, cadmium, chromium) in the soil in Surgut. We analyzed the soils in the areas affected by unauthorized dumps and adjacent areas with the same vegetation and soil cover that are not affected by dumps. A total of 12 sites are examined, of which 6 are contaminated and 6 are control sites. It has been established that the soil cover effected by dumps accumulates heavy metals, in concentrations exceeding the maximum allowable concentration by several times.
