Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
ErC50 (72 h) = 8.4 mg a.i./L for Skeletonema costatum (ISO 10253)
NOErC (72 h) = 3.5 mg a.i./L for Skeletonema costatum (ISO 10253)
Key value for chemical safety assessment
- EC50 for marine water algae:
- 8.4 mg/L
- EC10 or NOEC for marine water algae:
- 3.5 mg/L
Additional information
For the toxicity to algae, one study on marine algae is available for Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols.
The algae Skeletonema costatum was used for testing according to ISO 10253 and GLP. Test concentrations of 1, 5, 25 and 100 mg/L nominal were applied. This key study exhibited an EC50 (72 h) of 8.4 mg a.i./L and a related NOEC of 3.5 mg a.i./L based on growth rate (AnalyCen ecotox, 1998).
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.
