1 770 mg/L
EC10 or NOEC for microorganisms:
350 mg/L

Additional information

Key study:

The purpose of the 3-hour test was to evaluate the influence of the test item on the activity of activated sludge by measuring the respiration rate. Following concentrations were tested 1000, 1800, 3200, 5600 and 10000 mg/L.

The 3 h-EC10 and 3 h-EC50 values were calculated to be 350 and 1770 mg/L.

Supporting study:

The purpose of the 3-hour test was to evaluate the influence of the test item on the activity of activated sludge by measuring the respiration rate in accordance with OECD guideline 209. Following concentrations were tested 1000, 1800, 3200, 5600 and 10000 mg/L. The 3 h-EC10 and 3 h-EC50 values were calculated to be 894.07 and 3534.04 mg/L.
