Description of key information

The toxicity to microorganisms was assessed with the test item at nominal concentrations of 100 mg/L for 30 min. The EC50 was > 100 mg/L (nominal).

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
100 mg/L

Additional information

The activity of activated sludge was determined by measuring the respiration rate under defined conditions according to EU-method C.11. The respiration rate of the activated sludge was not or only slightly inhibited (> 10 %) up to the highest tested concentration of nominal 100 mg test substance/L. Therefore, the 30-min EC 50 is clearly higher than 100 mg/L under the present test conditions and the NOEC is 100 mg/L.
