Description of key information
Determination of the bacteria toxicity of FAT 41024/B (Activated sludge respiration inhibition test).
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The objective of this study was the determination of the test substance concentration, which reduces the respiration activity of activated sludge by 50 % (IC50 value).
Due to its physicochemical properties the test substance was not completely soluble in the test medium. The reported results are related to the amount of the test substance given into the test system. An IC50 value for the test substance could not be calculated.
Test substance:
IC50 > 1000 mg/l
IC20 > 1000 mg/l
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
