(Also known as: CDAA; alidochlor; CDAAT; randox; alidochlore ) |
Allidochlor is herbicide that is not generally approved for use in the developed world. It has a high potential for bioconcentration, has a moderate mammalian toxicity and is a known skin and eye irritant. Allidochlor is highly soluble in water and highly volatile. It is not persistent in the soil but is mobile. It is moderately toxic to fish. |
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.
