The contents of lead in soils, water, forage, grain, organs and muscle tissue of cattle were studied in two ecological zones of the Novosibirsk region differing in dominating of cattle breeds: Hereford (meat breed) and White-and-Black (dairy breed). The lead concentration in soils, forage and grain was determined using flame atomic absorption spectrophometer (Quantum-2A). The amount of lead in soils, forage, grain and water did not exceed the maximum permissible concentrations (MPC). Lead level in forage and soils did not differ between the zones. The analysis of organs and muscle tissue on the content of lead was carried out by atomic absorption method (spectrophotometer Shimadzu AA-7000). Average levels of lead were established for liver, kidneys, spleen, lungs and muscle tissue of the White-and-Black and Hereford breeds. The maximal content of lead was in liver of both breeds studied. The differences in the content of lead in lungs, liver and spleen have been revealed between the breeds. Considering the content of lead in the soil, roughage, grain, water, and in meat and byproducts, the territory of Western Siberia is suitable for ecological safe production.
