Description of key information
Additional information
Short term tests with species of 3 trophic levels are available for 1-N-butylpyridinium heptachlorodialuminate (CAS 67226-45-3). The test material was known to react violently on contact with water forming N-butylpyridinium chloride, hydrochloric acid and alumina. The study was therefore mainly performed on the test material degradation products and not the parent test material. Algae turned out to be the most sensitive species revealing an ErC50 (96h) of 7.5 mg/L. Short term effects of the substance towards fish and daphnia were an LC50 (96h) of >100 mg/L and an EC50 (48h) of 10 mg/L, respectively.The inhibition of the degradation activity of activated sludge is not anticipated due to anEC50 of 430 mg/L and a NOEC of 100 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
