SUMMARY |
Chinomethionat is a multi-use pest control substance that does not have EU approval for use. It has a low aqueous solubiltiy, a low volatility and, based on its chemical properties, would not normally be expected to leach to groundwater. It does not normally persist in soil or aquatic systems. Whilst chinomethionat is a skin and eye irritant, it is not highly toxic and no serious health issues have been identified. It is highly toxic to fish and algae but moderately toxic to most other species. |
