PHYSIOLOGICAL AND ENVIRONMENTAL MONITORING OF TECHNOGENIC XENOBIOTICS IN THE FOOD-ANIMAL-PRODUCTION SYSTEM
One of the main reasons that significantly affect the functional state of the organism, animal and human health, scientists and practitioners consider the environmental state of the environment. This is primarily due to the content of toxicants, in particular heavy metals in feed grown in areas of man-made pollution, the feeding of which leads to impaired metabolism in the animal body. Certain heavy metals (Pb, Cd, Hg, As, etc.) are highly toxic and can affect the body even in very small quantities. Therefore, monitoring the toxic elements in the soil-plant-feed-animal-production-human-chain trophic chain is considered a priority area in research, under conditions of man-made loading. The works of a number of leading scientists, in particular R. Y. Kravtsiv, O. I. Razputny, I. V. Kalinin, Yu. I. Savchenko, R. Fedoruk, indicate that the ability to the accumulation of toxic elements by organisms is determined not only by the geochemistry of the environment, but also by their biological nature and the biogeochemical chain through which the connection between organisms and the environment (soil-plant-animal-human). Unfavorable ecological situation in some regions is caused by violation of requirements for chemical fertilizers, plant treatment with pesticides (herbicides, pesticides, etc.), which is especially characteristic nowadays, when large agro-industrial structures (holdings, concerns, etc.) for the cultivation of intensive crops.
The mentioned reasons include animal and poultry growth promoters, certain groups of medicines, uncontrolled industrial emissions, man-made accidents, pollution of the environment by motor vehicle emissions, etc. As a result, the compounds of Plumbum, Cadmium, Hydrargyrum, Strontium and other heavy metals also enter the atmosphere. And what is characteristic (according to literature sources) is that some of them, together with atmospheric moisture, form even more toxic compounds, which in the form of rain fall on farmland and ponds, from where they enter plants and organisms of animals and food, in particular milk and meat. That is why it is necessary to carry out physiological and environmental monitoring, respectively, and control of the migration of harmful elements in the environment, in particular, their receipt and concentration in soils, plants of food groups, feeds, animals and food. In view of this, it is especially important to improve the diets of animals fed under conditions of techno-genic loading using sorbents and their biologically active additives. Such adsorbents R. Y. Kravtsіv and coauthors, O. O. Kalinin include zeolites that have adsorbing, ion exchange, catalytic and other properties, although their use should be carried out taking into account agro-environmental conditions, as well as the forms and properties of xenobiotics, which requires research with scientific and practical substantiation.
