Additional information

As regards the compartment air methanol is degraded in the atmosphere by photochemical, hydroxyl-radical dependent reactions, with a rate constant of 0.932 x 10^-12 cm³/molecule*sec (Atkinson, 1989). A half-life in the troposphere of about 17 – 18 days can be estimated. Methanol is thus slowely degraded by photochemical processes. With respect to the aquatic environment methanol, as an alcohol, lacks hydrolysable groups and is chemically stable in water.
