Additional information

In the atmosphere, benzyl alcohol probably exists almost entirely in the vapour phase. The gas-phase reaction with photochemically produced hydroxyl-radicals seems to be the primary atmospheric degradation pathway (half-life of 2 days). Wet deposition may also occur. Reactions with ozone and direct photochemical degradation are not expected to be important fate processes. In addition, photolysis, hydrolysis, volatilisation to the atmosphere and chemical oxidation are all expected to be slow processes in water (US EPA Document 1989).

Regarding the biodegradability of benzyl alcohol under aerobic and anaerobic conditions, several tests indicate a fast biodegradation of benzyl alcohol and it is concluded that benzyl alcohol is readily biodegradable (Trenel 1982, MITI 1992).

The Koc of Benzyl alcohol is calculated to be 15.7, which indicates that adsorption to sediment and suspended organic matter is not expected to be an important fate process. The Henry’s Law Constant is calculated to be 0.0879 Pa*m3/mol.

A calculated BCF of 1.37 indicates that Benzyl alcohol has no potential for bioaccumulation and bioconcentration in the aquatic and terrestrial compartment.
