Description of key information

The substance showed 0 % respiration inhibition of activated sludge at a test item concentration of 1000 mg/L. The effect value is related to nominal concentrations, since no analytical monitoring was performed. The study was conducted in accordance with OECD Guideline No. 209 (1984) "Activated sludge respiration inhibition".
(Currenta, 2009d)

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

As no adverse effects of the test item on the respiration of activated sewage sludge was overved at concentrations up to 1000 mg/L, that concentration can be scored as no-observed-effect-concentration as well.
