Administrative data

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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex VIII, the activated sludge respiration inhibition test does not need to be conducted because the registered substance is readily biodegradable. The applied test concentration in the key biodegradation study (100 mg/L) is in the range of concentrations that can be expected in the influent of a sewage treatment plant, and no inhibition effects on the activity of microorganisms was observed.
