Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
anaerobic degradation: 83-91 % conversion after 3 days to methane, CO2 and water
Key value for chemical safety assessment
Additional information
Methanol is readily biodegradable in freshwater and thus no additional information on degradation and simulation tests in soil or sediments is required according to Regulation (EC) No 1907/2006 (REACH). However, additional data on biodegradation in soil and sediments are available and presented here for the sake of completeness.
Oremland et al. (1982) studied the degradation of methanol in anaerobic sediments collected from the upper 15 cm of a salt marsh in San Francisco Bay. The sediments were highly reduced and contained methane and hydrogen sulphide. The sediments were homogenised anaerobically with San Francisco Bay water and 310-340 µmol methanol/flask was added to make up the inocula. After 3 days incubation, 83-91% conversion of the methanol had occurred. The products of methanol degradation were methane, CO2 and water. Boudemagh et al. (2006) showed that the time needed to eliminate 50% Methanol by various inocula is =< 8 hours.
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.
