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

Description of key information

In accordance with column 2 of REACH Annex VIII, activated sludge respiration inhibition testing is required (section 9.1.4). However, the study does not need to be conducted if 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 influence of a sewage treatment plant. Since the test substance was determined to be readily biodegradable in concentrations that can be expected in sewage treatment plants the conduction of an activated sludge respiration inhibition test is not needed.
