SCIENTIFIC JUSTIFICATION OF THE MEDICAL AND SANITARY REGULATION OF INDOXACARB INSECTICIDE IN THE AIR OF WORKING AREA

Abstract

Indoxacarb insecticide belongs to the class of oxadiazines, which are widely used in the agricultural industry for crop pest control, particularly lepidopteran insects. The mechanism of action of indoxacarb consists in the inhibition of sodium channels in the nervous system of insects, which, as a result, disrupts nerve impulses and causes paralysis and ultimately leads to the death of insects [4]. Its selectivity for insect sodium channels and minimal activity for mammalian channels contribute to its reputation as a safe and effective pesticide. Indoxacarb has been thoroughly evaluated to minimize its effects on non-target organisms such as mammals, birds and fish. An experimental setting toxicity parameters of indoxacarb with determination of the nature of the biological action on the body of laboratory animals and justification for maximum permissible concentration in the air of the working area were the purpose of the study. Toxicological parameters and the nature of the biological action of indoxacarb on the body of laboratory animals are provided according to the summarized data of the European Chemicals Agency and the results of a chronic toxicological experiment with intratracheal administration of the drug. It was found that indoxacarb, according to the parameters of acute toxicity, with a single oral administration and a single application to the skin, belongs to moderately dangerous substances (hazard class 3), with a single inhalation exposure, it belongs to highly dangerous substances (hazard class 2), exhibits a moderate irritating effect on mucous membranes eyes, does not cause resorptive-toxic, irritating effects when it comes into contact with the skin, has sensitizing properties. Indoxacarb causes a neurotoxic effect, does not have a mutagenic or carcinogenic effect. Conclusions. The parameters of toxicity, the nature of the biological effect on the body of laboratory animals were established, and the maximum permissible concentration of the insecticide indoxacarb in the air of the working area was justified.
