Applicant's summary and conclusion

Conclusions:
Ethyl lactate will be present mainly in air.
Executive summary:

A level III Fugacity calculation was performed for ethyl lactate with a version of 'LEVEL3B.BAS', as downloaded from the website of Trent University, Canada, adapted for MATLAB. A fugacity calculation clearly shows that ethyl lactate will be mainly present in air. Under the default compartment sizes used in the LEVEL3.BAS model, 92% of the amount of ethyl lactate present in the system is found in air.
