Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.
