Absorption coefficient of chemical elements in the system «soil-plant-animal-products»

The article reports the results of measurement of more dangerous for health chemical substances content in soils, plants, milk and beef. Their average values are showed. Besides the safety of system "soil - plant - animal - livestock products" of the Republic of Tatarstan is obtained. The coefficients of biological absorption of chemical elements in the links of the system are calculated. An increase of the level of the coefficient of zinc accumulation in plants and arsenic in milk and meat has been established. The need for further research when ranking territories based on the actual content of chemical elements in environment is explained
