Conclusions:
The 3 h IC50 for FAT 40066/A was found to be greater than 300 mg/l.
Executive summary:

The toxicity of FAT 40066/A to activated sludge was determined in a 3-h respiration inhibition test according to intenal standard method (CIBA Method 58) which is comparable to OECD Guideline 209. Based on the findings of the study, the 3 h IC50 of the test substance FAT 40066/A is greater than 300 mg/l.
