Endpoint:
activated sludge respiration inhibition testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant
Reason / purpose:
data waiving: supporting information

Description of key information

Based on the results from the toxicity control of a biodegradation study, no inhibitory effects on microorganisms were observed up to a substance concentration of 3 mg/L. The activated sludge test was, therefore, waived.

Key value for chemical safety assessment
