Chemical name: O,O-diethyl-S-[(4-oxo-1,2,3-benzotriazin-3(4H)-yl)methyl]phosphorodithioate Final regulatory action has been taken for the category: Pesticide Final regulatory action: The chemical is Banned Use or uses prohibited by the final regulatory action: All formulation containing Azinphos ethyl and all uses of this preparation prohibited from 25 September 2002. Pesticide use or uses that remain allowed: None. The final regulatory action was based on a risk or hazard evaluation: No Summary of the final regulatory action: The Pesticide Supervisory Board prohibited all formulations containing Azinphosethyl from 25 August 2002. The reasons for the final regulatory action were relevant to: Human health and environment Summary of known hazards and risks to human health: Azinphos-ethyl is extremely toxic following acute oral and dermal exposures. Users are exposed to risks. Mostly are not skilled and they don't have the necessary precaution while using the pesticide. It is toxic to non-target arthropods and it affects useful predators and parasitizes. There is not statistical risk assessment information in the country. Expected effect of the final regulatory action in relation to human health: Reduction of risks for human and environment. Summary of known hazards and risks to the environment: Animals In mammals, following oral administration, > 90% is eliminated in the urine and faeces within 2 days. The major metabolites are the monodesethyl compoundand benzazimide. Plants In plants, metabolites identified include azinphos-ethyl-oxon, benzazimide, dimethylbenzazimide sulfide and dimethylbenzazimide disulfide. Soil/environment Based on the Koc value and leaching studies, azinphos-ethyl can be classified as a compound with very low mobility. The half-life is several weeks. Metabolites formed in soil under aerobic and anaerobic conditions are: desethy azinphos-ethyl, sulfonmethylbenzazimid, bis(benzazim idmethyl)ether, methylthiomethylsulfoxide and methylthiomethylsuIfone. Expected effect of the final regulatory action in relation to the environment: Reduction of risk. Date of entry into force of the final regulatory action: 25/08/2002 It is used as an insecticide. |
