The article is devoted to the control of ecotoxicants content in mineral and organic substances of natural and artificial origin used in the production of feed additives and pharmacological veterinary agents. In the context of the growing technogenic load on the environment, the probability of detecting increased background levels of natural and technogenic ecotoxicants in mineral and organic raw materials for the production of feed additives and veterinary products increases significantly. In this regard, more attention should be paid to the study of substances of artificial origin with a minimum content of toxic and ballast components, as well as substances that have undergone technological processing to reduce their natural level of ecotoxicants. According to modern data, amorphous silicon dioxide is an effective, safe, economically available sorbing agent and it should be considered as a promising sorption-detoxifying agent for application under the influence of xenobiotics that differ in the toxicological action mechanism on the animal organism.

AbstractThe introduction of Si^+ ions and ions of other elements into amorphous silicon dioxide during their interaction causes damage to the structural bonds, which is observed in the vibrational spectral bands. Pure SiO_2 has no optical transitions but the bands of induced point defects appear in the photoluminescence spectrum when ions/neutrons are introduced. The generation of photoluminescence-active defects by fluxes of Ar^+ ion and thermal neutrons is compared. It is shown that the nature of damage to the structure is associated with both the specifics of the synthesis/processing of the material and the features of the interaction between the substance and ions (atomic collisions) and neutrons (collisions with atomic nuclei).
