Description of key information
An activated sludge respiration inhibition assay on the substance was conducted in accordance with Method C.11, Council Regulation (EC) No. 440/2008. An EC50 could not be determined, since all tested concentrations in the main test caused significant inhibition of respiration rate lower than 50%. The EC50 was estimated be > 1000 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The substance was shown to be not strongly inhibitory to the respiration rate of activated sludge from a municipal source, as experimentally determined in a guideline study.
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).
