Chlorpyrifos (Ref: OMS 971) |
Last updated: 22/08/2024 |
(Also known as: ENT 27311; chlorpyriphos; Dowco 179; chlorpyrifos ethyl) |
SUMMARY |
An organophosphate insecticide. It has a low aqueous solubility, is quite volatile and is non-mobile. There is a low risk of leaching to groundwater based on its chemical properties. It can be moderately persistent in soil systems but is not usually persistent in water systems. It is highly toxic to mammals, is classified as a reproduction toxicant, an acetyl cholinesterase inhibitor and a neurotoxicant. It is also a skin and eye irritant. It is highly toxic to birds, fish, aquatic invertebrates and honeybees and moderately toxic to aquatic plants, algae and earthworms. |
Data alerts |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
