Description of key information

The activated sludge respiration inhibition has been measured according to the OECD 209 test guideline in compliance with GLP.  Due to the high water solubility, the substance was exposed at nominal test concentrations up to 1000 mg/l.  The substance had no significant effect on the respiration of the sewage sludge and the EC50 is >1000 mg/l with a NOEC >= 1000 mg/l.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
1 000 mg/L
