SUMMARY |
Azinphos-ethyl is an organophosphate insecticide that is not approved for use in the EU. It has a low aqueous solubility, relatively volatile and is not expected to leach to groundwater. It may be moderately persistent in some soil systems but is not expected to be persistent in water. It is toxic to mammals and there is also concern regarding its potential to bioaccumulate. It is a neurotoxicant and an acetyl cholinesterase inhibitor. Azinphos-ethyl is highly toxic to birds, fish and aquatic invertebrates. It is moderately toxic to honeybees. |
