Applicant's summary and conclusion

Conclusions:
Results from the Level III fugacity model are:
Level III Fugacity Model
Mass Amount (%) Half-Life (hr) Emissions (kg/hr)
Air 0.86 1.02 1000
Water 48.2 360 1000
Soil 48.4 720 1000
Sediment 2.46 3.24e+003 0
Persistence time: 128 hr
Executive summary:

 EpiSuite v.4.0 has provided Level III fugacity model showing distribution of the substance. This method is considered adquate for assessment. Distribution of the substance is Air 0.9%, Water 48%, Soil 48%, Sediment 2.5%, with half life (hr) of air 1.02, water 360, soil 720 and sediment 3.24e+003.
