Additional information

Key study: Activated Sludge Respiration Inhibition test was performed in accordance with EEC method C11 and OECD Guideline 209. Samples of activated sludge (suspended solids 1.6 g/l), fed with synthetic sewage, were exposed for three hours to 0 (control), 50, 100, 300, 500 and 1000 mg/L of the test substance and their rates of oxygen consumption were determined and compared with those of controls. A three hour EC50, value of test item to activated sludge was determined to be greater then 1000 mg/l, the highest level tested.
