The organic carbon-water partitioning coefficient (Koc) calculated from the octanol-water partition coefficient (log Kow = 1.55) using the equation from the Technical Guidance Document (2003) (predominantly hydrophobics) is 22.7 l/kg (log value = 1.36). This predicted value is used in the assessment.

Using a Level I fugacity model, the theoretical distribution of TAME based on physico-chemical properties between four environmental compartments at equilibrium can be calculated. The results in indicate that 95.7% is distributed to the atmosphere and that volatilisation may be expected from water and soil and adsorption to particulate matter is poor.
