TOXICOLOGICAL PROFILE OF CITRIODIOL® INSECTICIDE

Abstract

In the last decade, insecticides obtained from plants have been actively used to fight mosquitoes. Before their use, it is necessary to evaluate their toxicity on laboratory animals. The purpose of the work was to experimentally establish the toxicity parameters of Citriodiol®, to determine the nature of the biological effect on the body of warm-blooded animals and to substantiate the maximum permissible concentration in the air of the working area. Citriodiol® insecticide was studied in acute, subacute and chronic experiments. The work was carried out on laboratory animals (male white rats, male white mice, ants and rabbits). It has been established that Citriodiol® insecticide is classified as a low-hazard substance (hazard class 4) based on the parameters of acute toxicity upon single oral administration. The average lethal dose for white rats is 5940 mg/kg. The clinical picture of acute poisoning is characterized by symptoms of damage to the central nervous system and irritant effects. Clinical signs of the toxic effect are most pronounced in animals that received the substance in doses of 7000 mg/kg - 11000 mg/kg. The death of animals was recorded against the background of adynamia, areflexia on the first day of the experiment. A single inhalation exposure to Citriodiol® does not cause the death of white mice and white rats. In the clinical picture of acute inhalation toxicity, symptoms of upper respiratory tract irritation and hypodynamia are observed. Citriodiol® has a mild irritant effect when it comes into contact with the skin and a strong irritant effect when it comes into contact with mucous membranes. Subchronic oral administration of Citroidiol®c causes the development of a clinical picture of intoxication, which develops on the 20-21st day of the experiment and is manifested by a decrease in motor activity. The cumulation ratio exceeds 8.0 and indicates weak cumulative activity. Chronic inhalation exposure does not cause the death of animals. A decrease in body weight, a change in hematological and biochemical parameters of the body of laboratory animals is observed. Citriiodiol® does not cause sensitization when applied to the skin and does not show mutagenic properties. Conclusions. The parameters of toxicity, the nature of the biological effect on the organism of laboratory animals were established, and the maximum permissible concentration of the insecticide Citriodiol® in the air of the working area was substantiated.
