The work of the agrarian sector of the economy is impossible without deep awareness of the serious environmental situation threat of anthropogenic factors’ influence due to the increasing intensification system of processes in animal husbandry. In addition to understanding the processes occurring in connection with the increase in anthropogenic load, real-time information about the real situation in the agroecosystem is necessary. Forecast of decision-making, consequences of certain actions. Control and monitoring of changes in the environmental situation. Therefore, the current control and the real system for assessing the ecological situation is important for the correct ecological activity of the agrarian organization. The greatest ecotoxicants’ concentration is observed in the body of experimental animals, most of all in the respiratory and excretory organs. The minimum level of ecotoxicants was observed in muscle tissue, hence it is an environmentally friendly livestock product. The concentration of arsenic, mercury in the experiment is at the level of trace indicators. The level of ecotoxicants’ accumulation in drinking cow’s milk was established, the correlation between the pollutants’ level in the product and the location of agricultural production, season and production time was found.
