Description of key information
The 180-min IC50 (growth inhibition) to activated sludge from a predominantly domestic source was determined to be 186 mg/L (OECD 209). A supporting study (ISO 8192 -1986) determined a 180-min EC10 (respiration inhibtion) to sewage at >10000 mg/L, however, the sludge was presumably pre-adapted (industrial source).
Key value for chemical safety assessment
- EC50 for microorganisms:
- 186 mg/L
Additional information
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.
