Additional information
The test substance was not completely soluble in test medium at the loading rates initially prepared. Therefore, the test substance – Milli-RO water mixtures were magnetically stirred for a period of approximately 25 hours. Subsequently, synthetic medium, sludge and Milli-RO water were added resulting in the required loading rates. Optimal contact between the test substance and test medium was ensured applying continuous aeration and stirring during the 3-hour exposure period.
4-(1-methyl-1-phenylethyl)-N-[4-(1-methyl-1-phenylethyl)phenyl]aniline was not toxic to waste water (activated sludge) bacteria at or below a loading rate of 1000 mg/l (NOEC).
The EC50 exceeded a loading rate of 1000 mg/l.
