Abstract

The technogenic Clarc of lead (Pb) and cadmium (Cd) from the upper soil layer and the forage plants in an industrially polluted region, so as the Pb and Cd input in the organism of young lambs and kid by the synthesis of secondary biological production have been investigated. For the synthesis of 1 kg secondary production in the organism of lambs, the input of Pb with the food and drinking water is 6.44 mg and 2.46 mg Cd and in the kid- organism- 21.41 mg Pb and 5.29 mg Cd. The obtained production in conditions of increased technogenic Clarc is with higher content of Pb and Cd, according the maximal admissible levels (EC- regulation 466/2001).
