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:
The substance is assessed to be readily biodegradable. In a study conducted according to OECD 301 A with the structurally highly similar substance sodium 2-hydroxyethanesulphonate (CAS No. 1562-00-1) no inhibition of activated sludge respiration was observed at a test substance concentration of 121 mg/L.
