The results reflect that the ultimate fate of 1-tetradecanol is dependent on its route of release into the environment.1-Tetradecanol released to air would partially precipitate to soil and water. There is relatively little movement between soil and water, because transfer via the air compartment is very slow, for a substance of low volatility. In water, the adsorption coefficient of 1-tetradecanol results in significant adsorption to sediment.

Applicant's summary and conclusion

Conclusions:
Two models have been used to predict distribution of decanol in the environment:
- The 1997 Level I model implemented as 'EQC'
- The 1999 Level III model, available on the Canadian government web site.

The results reflect that the ultimate fate of 1-tetradecanol is dependent on its route of release into the environment. 1-Tetradecanol released to air would partially precipitate to soil and water.
