SUMMARY

Carbophenothion is an insecticide that no longer has approval for use within the EU. The substance has a low aqueous solubility, low volatility and, based on its chemical propeerties, would not be expected to leach to groundwater. It may be quite persistent in soil systems. It is highly toxic to mammals and may also be a cholinesterase inhibitor and a neurotoxin. In most instances it shows a moderate to high level of toxicity to aquatic and terrestrial species.
