Description of key information
Bacteria Toxicity of FAT 40815/A (Activated Sludge Respiration Inhibition Test). Test performed under GLP conditions and according to OECD Guideline 209 and EC method of the Directive 67/548 L133 Part C.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
No significant inhibition of the respiration rate of the activated sludge was observed (% inhibition of the respiration rate < 15%). Therefore the IC20- and IC50- values were estimated as follows :
IC50 (3h) of FAT 40815/A: > 1000 mg/L
NOEC (3h) of FAT 40815/A: >= 1000 mg/L
