Applicant's summary and conclusion

Conclusions:
Substance will primarily partition to the aqueous phase
Executive summary:

Mackay fugacity modelling (level 1) indicates that, in the absence of degradation, virtually all of the substance (>98%) would partition to the aqueous phase. Of the remaining amount, this is partitioned approximately 2:1 between the air and soil.
