Applicant's summary and conclusion

Conclusions:
TAEE is mainly distributed to the atmosphere (93.1%) and volatilisation may be expected from water and soil. Adsorption to particulate matter is unlikely to occur.
Executive summary:

Using a fugacity model (level I) (Fugacity based EQC Equilibrium Criterion Model v3.00 [Canadian Environmental Modelling Centre, 2004]), the theoretical distribution of TAEE based on physico-chemical properties between four environmental compartments at equilibrium can be calculated. The results indicate that 93.1% is distributed to the atmosphere and that volatilisation may be expected from water and soil. Adsorption to particulate matter is unlikely to occur.
