Description of key information
The study was performed according to OECD Guideline 209 and GLP guidelines.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
- EC10 or NOEC for microorganisms:

Additional information
As the substance was hardly soluble in water, test concentrations were prepared separately in Milli-RO water. Initial loading rates of 200 mg/L were mixed thoroughly, followed by a stirring period of at least 24 hours in the test bottles. Subsequently, synthetic sewage feed and sludge were added resulting in final loading rates of 100 mg/L.
No inhibition of respiration rate of the sludge was recorded at a final loading rate of 100 mg TS per litre.
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.
