Description of key information
The test substance is not harmful to activated sludge. The EC50 lies above 10000 mg/L
Key value for chemical safety assessment
- EC50 for microorganisms:
- 10 000 mg/L
- EC10 or NOEC for microorganisms:
- 5 000 mg/L
Additional information
The inoculum was 1.6 g/L; the graph of the dose-effect curve shows that there is no dose-dependency at concentrations of 2500, 5000 and 10000 mg/L.
Due to the nearly parallel curve progression to the "concentration axis" it is assumed that there is definitely no inhibition up to a concentration of 5000 mg/L and most likely no inhibition at a concentration of 10000 mg/L.
Remazol Schwarz B is not harmful to activated sludge. The EC50 lies above 10000 mg/L
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
