study was performed to assess the effect of the test material on the
respiration of activated sewage sludge. The method followed that
described in the OECD Guidelines for Testing of Chemicals (1984), No.
209 "Activated Sludge, Respiration Inhibition Test".
sewage sludge was exposed to directly added test material at
concentrations of 1, 10, 100, 1000 and 10000 ppm, a duplicate control
group, and an assessment of the sensitivity of the inoculum used in the
test to a reference toxicant 3,5-dichlorophenol. The
test duration was a 3 hour exposure period at 20 degrees C to the test
material followed by measurement of oxygen consumption.
