Description of key information
The key study is the only available study for toxicity to microorganisms. In a reliable ASRI study the 3-hour EC50 was >1000 mg/l and the NOEC was at least 1000 mg/l (WIL, 2009).
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
In an activated sludge respiration inhibition study conducted in accordance with OECD 209 and in compliance with GLP, the 3-hour EC50 was >1000 mg/l, the highest concentration tested (WIL, 2009). Although not stated by the study authors, the No Observed Effect Concentration (NOEC) was 1000 mg/l as no inhibition of respiration rate was observed at any test concentration.
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.
