Additional information
Procedure
The test material was aerated for a period of 3 hours at 21°C in the presence of activated sewage sludge with the addition of a synthetic sewage as a respiratory substrate. The rate of respiration was determined after 30 minutes and 3 hours contact time and compared to data for the control and a reference material, 3,5-dichlorophenol.
Results
The effect of the test material on the respiration of activated sewage sludge gave a 3-Hour EC50 of greater than 1000 mg/L.
