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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
