DERMAL ABSORPTION OF DIQUAT AND POTENTIALOCCUPATIONAL RISK

Abstract

OBJECTIVE: The aim: The toxicological-hygienic assessment of dermal absorption of diquat in terms of potential risk of its bioavailability in professional use. PATIENTS AND METHODS: Materials and methods: The object of the study was cutaneous exposure of diquat, determined in toxicological experiments of different duration (data of scientific literature) and at the stage of state testing of pesticide preparations based on diquat dibromide (data of a full-scale hygiene experiment, prognostic model of risk assessment), the technical concentrate of diquat dibromide (active substance content not less than 377 g / kg) contains relevant supplements, the content of which is regulated by the Food and Agriculture Organization. RESULTS: Results and conclusions: Due to the high risk of the diquat adverse effects affecting the personnel, general public and environment, the European Union has introduced administrative decisions to forbid plant protection products containing the diquat. Fulfillment of the conditions of the Association Agreement between Ukraine and the European Union indicates the need to develop common regulations and risk assessment methods aimed at ensuring high level of protection of human health and the environment.
