Additional information

Two reliable studies are available for C12 -14 AO. In the key study, Pseudomonas putida were exposed to nominal concentrations of 0, 50, 100, 600, 1000, 10000 or 100000 mg/L of C12 -14 AO for 18 hours in a Bringmann-Kohn test [Kolvenbach M (1990)]. The EC10, based on reduction in growth rate, was 24 mg AO/L.
