In the Tyva Republic among ail the types of HM pollution; the highest pellutioin level is referred to cadmium, lead and arsenic. We examined Fe, Zn. Cu content in 53 types of feeds. Plant species differentiate for the degree of HM accumulation. Cadmium content was several times higher (0.10 mg/kg) in cereal-legume hay than in fen and oat hay (0.015 mg/kg). ln the hay of tarragon and mixed grasses lead level was 10 times higher (1.66 mg/kg) than in fen and oat hay. rn general the level of HM content can be presented as the following chain: $\rm Fe>Cu>Zn>Pb>Cd>Co>As>Hg$. Cadmium content was considerably higher in cereals of the TR than in the identical plants of Semipalatinsk Pryirtysh (Kazakhstan Republic). The data obtained can serve as a reference-point for monitoring heavy metals in other areas of Russia.
