RESUMEN

Dimethoate is an organophosphate insecticide approved for use in the EU and in other parts of the world. It is highly soluble in water, has low groundwater leaching potential and is volatile. It is non-persistent in soil, mobile but does not normally persist in aerobic aquatic systems. It is moderately toxic to mammals but may have serious health implications for humans as it is an acetyl cholinesterase inhibitor and may cause reproduction or development effects. It is highly toxic to birds and honeybees, moderately toxic to most aquatic species and earthworms.
