Applicant's summary and conclusion

Conclusions:
According to a Mackay level I calculation cis-cyclooctene will be distributed almost exclusively to the atmosphere (99.86 %) while distribution to other compartments is negligible (< 0.1 %).
Executive summary:

The distribution among different compartments of cis-cyclooctene was explored through a Mackay level I model calculation. The results indicate that the relevant compartment for this chemical is the atmosphere, representing 99.86 % of the distribution. Dissipation to other compartments is negligible (< 0.1%).
