Section 12: Ecological Information
Ecotoxicity: Not available.

Products of Biodegradation:
Possibly hazardous short term degradation products are not likely. However, long term degradation products may
arise.
Toxicity of the Products of Biodegradation: The products of degradation are less toxic than the product itself.
Special Remarks on the Products of Biodegradation:
Methanol in water is rapidly biodegraded and volatilized. Aquatic hydrolysis, oxidation, photolysis, adsorption to
sediment, and bioconcentration are not significant fate processes. The half-life of methanol in surfact water
ranges from 24 hrs. to 168 hrs.
Based on its vapor pressure, methanol exists almost entirely in the vapor phase in the ambient atmosphere. It is
degraded by reaction with photochemically produced hydroxyl radicals and has an estimated half-life of 17.8 days.
Methanol is physically removed from air by rain due to its solubility. Methanol can react with NO2 in pollulted to
form methyl nitrate.
The half-life of methanol in air ranges from 71 hrs. (3 days) to 713 hrs. (29.7 days) based on photooxidation
half-life in air. (Methyl alcohol)
