[Accumulation of heavy metals in cereal crops and ways of reducing their levels].

The study deals with the levels of heavy metals in the raw grain grown in the agricultural lands of the Oryol Region and provides the results of a trial of a complex enzymatic agent based on phitase and succinic acid used to reduce the levels of heavy levels in the wheat and rye grains during manufacture of grain bread. The use of the complex-acting enzymatic agent based on phitase obtained from the fungus Penicillium canescens in combination with 0.1% succinic acid of the mass of wheat and rye grains when the latter is prepared for the manufacture of grain bread has been established to reduce the concentrations of nickel, lead, cadmium, and chromium, by lowering the levels of MAFAM, spore-forming bacteria, moulds, and yeasts in the raw materials.
