Our article presents the study of the content of highly hazardous and moderately hazardous chemical elements in soils, plants, beef and cow milk. Their average amount is shown. A safe level of the concentration of these chemical elements in the links of the chain “soil - plant - animal – meat and dairy products” of the Republic of Tatarstan is revealed. The coefficients of biological absorption of chemical elements in the links of the system are calculated. An increase in the coefficient of accumulation of Zn in plants and As in milk and meat was found. Further research for ranking territories according to the actual content of chemical elements in environmental objects is required.
