Abstract
Due to the problems of environmental pollution with heavy metals (TM), many of which are toxic, the organic matter of the soil undergoes specific physico-chemical interactions with them both at the level of humic and fulvic acids. Soils are able to accumulate toxic substances in the humus horizon, including due to the processes of complex formation. The study of the stability of such compounds, their distribution over horizons depending on the type of soil, translocations in the soil-plant system largely determine the ecological component of agricultural products. In this regard, the migration of lead and cadmium in the soil-spinach plant system of the "Krepysh" variety was studied with an assessment of the phytotoxicity of the soil.
