Description of key information
Guideline 209: Activated Sludge, Respiration Inhibition Test (Carbon and Ammonium Oxidation). Reliability=K1;
Under
the test conditions, BPAF/BPAF:BTPP-Salt showed no inhibition at the 100 mg/L
dose level and slight inhibition at the 10 and 1000 mg/L dose levels,
1.77% and 13.06%.
The EC15 and EC50 values were not attainable as the highest dose level tested
has a mean inhibition rate of 13.06%. The abiotic treatment mixture with
dose level
of 1000 mg/L of the test substance had a respiration rate of 0.0 showing
there was
no significant uptake or released of oxygen resulting from abiotic
reactions.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
