The 3-h EC50 value is >100 mg/L as determined in a mixed culture of bacteria.

Key value for chemical safety assessment

EC50 for microorganisms:
100 mg/L

Additional information

The IC50 of the testsubstance was determined in a respiration inhibition test performed according to OECD guideline 209 (CG 1987). In this study, a mixed culture of bacteria (sludge of a Husman apparatus) was exposed to 0, 1, 3.2, 10, 32 and 100 mg/L test substance for 3 hours. No effects on algal respiration were observed. The IC50 was determined >100 mg/L.
