Copper acetoarsenite (Ref: ENT 884)

(Also known as: Paris Green; acetoarsenite de cuivre; French green)

Copper acetoarsenite is an obsolete insecticide and wood preservative that was m ainly used to control termites and wood-damaging insects. Little is known about its environmental fate or toxicity to fauna and flora. It is highly toxic to mammals and is a known carcinogen.

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.
