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

The toxicity to microorganisms endpoint is waived as the substance is qualified as readily biodegradable in an OECD TG 310 study, at an applied test concentration of 25.7 mg/L which is in the range of concentrations that can be expected in the influent of a sewage treatment plant. The test concentration of 25.7 mg/L can be used as a NOEC value.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
25.7 mg/L
