- 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

Key value for chemical safety assessment
Additional information
In accordance with Column 2 of REACH Annex VIII, the activated sludge respiration inhibition study (required in Section 9.1.4 of REACH Annex VIII) does not need to be conducted as the substance is readily biodegradable and the applied test concentrations are in the range that can be expected in the influent to a sewage treatment plant.
Section R.7.8.16.1 of REACH Guidance R7b (ECHA, 2008) states the following: If a compound degrades well in a ready biodegradability test, or does not inhibit the degradation of a positive control at a certain concentration, this concentration can be used as a NOEC value.
Tetrahydrofurfuryl alcohol degradation well in a ready biodegradability test at a concentration of 100 mg/l (nominal), and this concentration is therefore used as a NOEC value.
