Results above are for first scenario shown below.
Results shown below are for emissions of ~10,000tpa with different potential emission patterns for comparison.

From this it can be concluded that air concentrations are effectively independent of emission compartment, emissions to the water compartment remain in the same compartment (with some partitioning to sediment) whilst emissions to soil partition to all three compartments.
Applicant's summary and conclusion
- Conclusions:
- Environmental background levels of ethyl acetate at regional and continental levels from emissions of ethanol during use are not likely to be of concern.
- Executive summary:
Level III fugacity calculations based on realistic emissions quantities predict that environmental levels of ethyl acetate will be very low (<25ug/l in water, <1.5ug/kg in soil, <2.5ug/kg in sediment and <3.5ug/m3 in air.)
