The data about the content of macro -and microelements in main types of soils and types of forage herbs on the agricultural lands of agricultural and industrial districts of the southern Siberia have been presented by ecological and bio-and geochemical criteria. The work is aimed at analyzing the results of the study and assessing the content of macro -and microelements in main types of soils and types of forage herbs on farmland of agricultural and industrial areas of the southern Siberia and their influence on animal health by ecological and bio-and geochemical criteria. Total (gross) content of macroand microelements (As, B, Ba, Be, Ce, Co, Cr, Cu, Fe, Ga, La, Mn, Mo, Nb, Ni, P, Pb, Se, Sn, Sr, Ti, V, Y, Yb, Zn, Zr) in samples of soil was determined by the method of optical atomic emission spectrometry with the use of a double-jet argon plasmatron. In nitric-acid solutions of plants ash, K, Na, P, Ca, Mg, Li, Fe, Mn, Zn, Co, Cu, Pb and Cd were determined by flame atomic absorption spectrometry (FAAS) on an AAnalyst400 (Perkin Elmer) spectrometer. The result of the studies has shown that in soils and fodder herbs of agricultural districts of Siberia, the content of heavy metals -Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Zn, Sr -does not exceed the environmentally acceptable levels. In herbs, the concentration of Co, Cu, Mo and Zn was less than the values of the biogeochemical norm required for farm animals. It does not correspond to the Ca/Sr ratios in gramineous grasses and especially in legumes on the saline soils of the forest-steppe and steppe, as well as the Ca/P ratios in perennial and annual gramineous grasses, which may result in poor animal health, the quantity and the quality of their products. In industrial districts of Kuzbass, the dependence of heavy metals concentration in forage herbs of farmland on the level of gas-and-dust pollution of the environment by a metallurgical company has been determined. In the territory of the Republic of Tuva, in the areas of extraction of non-ferrous metal ores with local areas of technogeneous contamination of soils, plants and waters with heavy metals, pathologies in development and higher perinatal death of yaks were detected, as compared to the environmentally safe locations of their breeding.
