Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
In accordance with column 2 of REACH Annex IX, the study for biodegradation in water and sediment does not need to be conducted since the substance is readily biodegradable.
However, the study of Van Vlaardingen and Van Beelen (1994) serves as supportive information. The study, not following a specific guideline, was ranked “reliable 3” since a blank control was not added and exact sampling time points and pH of the treatments are uncertain. Anaerobic mineralization of acetate in two river Rhine sediments was investigated at 20 °C in sealed bottles and showed a rapid, first order kinetic with DT50 values of ~ 0.5 h (< 2% 14C-acetate left at the test end, total recovery of radioactivity was 90%).
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
