In a 3 h toxicity study, the activated sludge from a domestic waste water treatment plant were exposed to 3,3,5-Trimethylcyclohexanon at nominal concentrations of 10, 32, 100, 320, and 1000 mg/L under static conditions in accordance with the OECD guideline No. 209 (1984). The 3-h EC50 value based on the measured inhibition rates, were calculated to be 755 mg/L. At the highest nominal test concentration of 1000 mg/L, an inhibition rate of 64.1 % was found.
