Additional information

One study (1997, Ciba) was performed on FAT40564/A following OECD 209 to determine the inhibitory effect on the respiration activity of activated sludge. The inhibitory effect of the test substance at a particular concentration was expressed as a percentage of the mean respiration rates of two controls and IC50 was determened to be > 1000 mg/l for the tested substance and IC50 was 9.0 mg/l for the reference substance (95% confidence limits 6.93 - 11.26 mg/l).
