Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Based on read across, alkenes C11/13/14 are not inhibitory to microrganisms at a concentration of 2mg/l
Key value for chemical safety assessment
Additional information
Miller and Watkinson (1984) investigated the toxicity of alkenes C10 -14 to activated sewage sludge as part of a ready biodegradability screening test. The study was conducted to standard guidelines (OECD 301D) and the validity criteria of the test guideline were met. After 5 days >25% biodegradation was observed in the test vessels containing both test and reference material. Therefore, microbial respiration was not found to be significantly inhibited at the concentration tested. In the same study (Miller and Watkinson, 1984) the toxicity of alkenes C10 -14 to Pseudomonas fluoresens was also investigated following a TNO guideline. This study found the IL50 to be >1000 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.
