EC50 > 10,000 mg/L, ISO 8192 guideline, Müller (1992).
The effect of the test material on the respiration rate of activated
sludge was investigated in a GLP study conducted according to the ISO
8192 guideline, which in most parts is similar to the OECD and EU test
methods. A defined amount of activated sludge was mixed with synthetic
nutrient solution and the rate of respiration was measured. The
respiration rate was compared with those measured in assays with
different concentrations of the test material. The sensitivity of the
activated sludge used was verified with 3.5 -dichlorophenol as a
reference substance. The EC50 under the conditions of the study was
determined to be > 10,000 mg/L.
The study was performed in line with GLP and to a standard guideline
with incomplete reporting or methodological deficiencies which do not
affect the quality of the relevant results and was assigned a
reliability score of 2.
