 The NOEC is equal to or greater than 1000 mg/l.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

One test with activated sludge was considered to be valid.

The respiration rate of the microorganisms in the test solution of 1000 mg/l was equivalent to that of the controls. The EC50 for aquatic microorganisms is greater than 1000 mg/l and the NOEC is equal to or greater than 1000 mg/l.
