Description of key information
In an activated sludge respiration inhibition test (aerobic bacteria) there was an effect concentration of EC20 > 100 mg/L, EC50 > 100 mg/L and EC80 > 100 mg/L observed after 3 hours.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
Additional information
The microbial toxicity of the test substance was studied in a growth inhibition test used settled sludge as inoculum acc. to the method described in EEC L 133, p. 118f (1988). The 3h-EC50 was determined to be > 100 mg/L and the 3h-EC20 was determined to be > 100 mg/L (CIBA-GEIGY, 1990).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
