Description of key information

The test substance was tested in a respiration inhibition test with domestic sewage sludge as inoculum. No effects on respiration were detected at 100, 320 and 1000 mg/L after 3 hour exposure. The EC10, EC20, EC50 and EC80 values of the test substance were estimated to be >1000 mg/L nominal concentration.
The no observed effect concentration (NOEC) was 1000 mg/l.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

The EC50 is above 1000 mg/L
