[Increase in respiration rate as compared to controls]
An activated sludge respiration inhibition test (according to OECD
guideline 209) with activated sludge from a predominantly domestic
sewage treatment plant resulted in a 3-h EC50 value of greater than 1000
mg/L. The No Observed Effect Concentration (NOEC) after 3 hours
exposure was 1000 mg/L.
