Description of key information
Method C.11 - Activated Sludge Respiration Inhibition Test, Directive 88/302/EEC. Published in OJ L 133 1988.
GLP study
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
Results of the respiration inhibition test
On the basis of the effective concentrations describing the respiration inhibition of activated sludge caused by the test substance the EC50was found to be:
EC50> 1000 mg.L-1
Under the current experimental conditions, all tested concentrations in the main test provided no significant inhibition of respiration rate Therefore it was not possible to calculate the EC50 value.
