Description of key information

biodegradation: 71.5 - 95 % (freshwater, wastewater), 69 - 97 % (marine water)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Methanol is readily biodegradable in freshwater based on the results of standard ready tests that show 71.5 – 95 percent removal after 5 and 20 days, respectively (Price et al. 1974; Wagner 1976). In marine water degradation rates were found between 69 - 97 % (Price et al. 1974).
