Description of key information

IC 50 (3 h) >100 mg/l

Key value for chemical safety assessment

Additional information

The inhibitory effect of the substance on aerobic waste-water bacteria was investigated in two respiration tests, both according tothe OECD Guideline 209 (1984). The substance showed at the highest concentration tested (100 mg/l) no inhibition (-4.1 %) and a slight inhibition (18.0 %) of the respiration rate in the fist and the second test respectively.

The IC 50 (3 h) was determined to be >100 mg/l in both tests and so the substance was found not to be toxic to waste-water bacteria.
