Additional information

The inhibitory effect on aerobic waste-water bacteria was investigated in a respiration test according to the OECD guideline 209.

The test article showed only a slight inhibition (19.1 %) of the respiration rate up to a concentration of 100 mg/l.

The substance was found to be non-toxic to waste-water bacteria. The IC 50 for dichlorophenol tested under the same conditions was about 12 mg/l.

The IC 50 (3 h)was determined to be > 100 mg/l.
