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.
