Currently, the main directions of scientific research in the field of agriculture are related to the issue of environmental protection and the rational use of natural resources. This issue is especially acute in relation to the soil. Its contamination occurs with substances of chemical and biological origin above the maximum permissible concentration (MPC). The main source of soil pollution in arable land is waste from livestock complexes, agricultural chemicals (fertilizers, pesticides), exhaust gases from vehicles, sewage from settlements. The article presents the results of a study of the dependence of the content of heavy metals in livestock products on their concentration in plant feeds. The results of monitoring the content of heavy metals in the main feeds showed that the concentration of metals in the studied plants does not exceed the MPC, with the exception of Cu and Zn in grasses of natural pastures. The content of heavy metals in animal products (milk, sour cream, cottage cheese and meat) it depends on their content in plant feeds, but does not exceed the maximum permissible concentration, with rare exceptions.
