Study design

Environmental properties:
Default values were assumed for environmental compartment descriptions, dimensions, and properties, advective and dispersive properties. Chemical-specific input parameters were:
molecular weight = 520.50 g/mol;
melting point = 187.50 °C; and
boiling point of 314 °C.
Emissions were assumed to be equally to air, water and soil.

Results and discussion

Percent distribution in media

Air (%):
0.1
Water (%):
1.18
Soil (%):
37.2
Sediment (%):
61.6
Other distribution results:
Air: t1/2 = 16.1 hr; emissions = 1000 kg/hr
Water: t1/2 = 3600 hr; emissions = 1000 kg/hr
Soil: t1/2 = 3600 hr; emissions = 1000 kg/hr
Sediment: t1/2 = 14,400 hr; emissions = 0 kg/hr

Any other information on results incl. tables

Percent in air was actually noted as <0.1 %

Applicant's summary and conclusion

Conclusions:
Air < 0.1 %
Water = 1.18 %
Soil = 37.2 %
Sediment = 61.6 %
