Abstract
The purpose. To determine accumulation of heavy metals (Pb, Cd) in pork at use of different doses of protein vitamin mineral additive (PVMA) in feed grain mixture in conditions of Polisya (III zone of radioactive impurity). Methods. 3 groups of experimental pigs were formed: I group (control) — was fed with grain mixture 1 (20% of PVMA); II group (experimental) — was fed with grain mixture 2 (10% of PVMA + 10% of field pea); III group (experimental) — was fed with grain mixture 3 (10% of PVMA + 10% of lupin). Determination of Pb and Cd was carried out using atomic absorption spectrometer «Quant-2A». Results. Feeding young pigs with grain mixtures of different contents influenced accumulation of Pb and Cd in the longest muscle of a back and a liver of animals. Density of Pb and Cd in killing products of pigs was below MPC. Conclusions. Substitution in grain mixture of 10% (on mass) of PVMA with analogous amount of kibbled grain of field peas and lupin at fattening animals in III zone of radioactive impurity negatively affects quality of pork, increasing in it density of Pb and Cd (for 10,5-57,9 and 33,3% accordingly).

Key words: pork, protein-vitamin-mineral additive, field pea, lupin, lead, cadmium.
