Study of the degree of heavy and toxic metal pollution of soils and forages of peasant farms in the almaty region

Abstract

The present article provides the interim results of the grant project “Veterinary and sanitary control and monitoring assessment of migration of heavy metals in the food chain "water-soil-feed-products"” to the study of heavy metal pollution of soil and plant-based forages on the territory of Almaty region of. The levels of Hg, Cd, Pb, andAs have been defined in the arable layer of soils in the basic farms. The compounds of toxic elements in forages used in the diets of milking cows have been monitored.Main types of soil, feed (hay, silage, haylage, concentrates) served as research materials.
