Description of key information
Additional information
Since no test data on the aquatic toxicity of isooctene (CAS-No.: 11071 -47 -9) are available a conclusion by analogy approach to di-n-butene has been applied.
Acute tests on all three trophic levels were performed to examine the aquatic toxicity of di-n-butene. The waterfly Daphnia magna turned out to be the most sensitive species revealing an EC50 (48h) of 3 mg/L. Thus, di-n-butene is considered to be acutely toxic to aquatic organisms. Effects of di-n-butene towards fish and algae were found in the same range providing a LC50 (48h) of 8.9 mg/L for fish and an EC50 (72h) of 4.3 mg/L for algae.
No data on long-term toxicity on fish and Daphnia are available.
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.
