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 0.539 0.521 1000
Water 57.1 360 1000
Soil 39.5 720 1000
Sediment 2.91 3.24E+03 0
Persistence time: 108 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 0.5%, Water 57%, Soil 40%, Sediment 2.9%, with half life (hr) of air 0.5, water 360, soil 720 and sediment 3.24e+003.
