Abstract

The article is devoted to the study of the possibility of using the soils contaminated with heavy metals in agricultural production.

For the first time, in order to establish the guaranteed suitability of the soils contaminated with heavy metals for unrestricted economic use, the experiment on the translocation of heavy metals from the soil to agricultural plants has been carried out under conditions of extreme concentrations of heavy metals in the soil.

It is shown, that:

—        soils, even contaminated with high concentrations of lead and copper, are quite suitable for obtaining a sanitary-safe harvest of many agricultural plants;

—        the presence in the soil of cadmium is safe in concentrations not much exceeding 1 MAC;

—        the content of TM during translocation from soil to agricultural products is significantly reduced in all investigated agricultural plants, except for beets;

—        the commodity cultivation of beets on the lands, the concentration of TM in which is close to 1 MPC, can be dangerous because the beet accumulates a very large amount of TM (experiments were conducted with beets of different varieties).

Keywords

land cost, heavy metals, an ecological damage, a quantitative estimation of a damage, ecological safety.
