SUMMARY |
Mevinphos is a highly toxic organophosphate insecticide. Known to cause significant inhibition of cholinesterase (ChE) activity by all routes of exposure. Readily soluble in water, volatile, slow aquatic hydrolysis, rapidly degrades in soil. Whilst the molecule is potentially mobile, it would not be expected to leach into groundwater due to rapid soil degradation. Extremely toxic to aquatic invertebrates, birds and mammals. |
