Materials and methods
- Model:
- calculation according to Mackay, Level III
- Calculation programme:
- Level III Fugacity Mode, EpiSuite v4.1 - US EPA tool - The model in EPI Suite is a direct adaptation of the methodology and programming approach developed by Dr. Donald Mackay and co-workers (Mackay et al., 1996a, 1996b; Mackay 1991).

Study design
- Test substance input data:
- Smile notation: BrCCCCCCBr
- Environmental properties:
- Input parameters were all default value of EpiSuite - fugacity model (Level III) - Emission value mode: The default environmental emission rates are 1000 kg/hr to air, water and soil (sediment has a value of zero); these are the default parameters used in the EQC model and adapted in EPI Suite.
Results and discussion
Percent distribution in media
- Other distribution results:
- According to the following physchem value of 1,6-dibromohexane:
- Molecular weight: 243.97
- Henry's LC: 0.000614 atm.m3/mole (Henrywin program)- refer to section 5.4.2 for details
- Vapor pressure: 0.0555 mm Hg (Mpbpwin program) - refer to section 4.6 for details
- Log Kow: 3.97 (Kowwin program) - refer to section 4.7 for details
- Soil Koc: 437 (KOCWIN MCI method)- refer to section 5.4.1 for details
1) If 1000 kg/hr emission to water:
* Air: 7.21%
* Water: 90.4%
* Soil: 0.249%
* Sediment: 2.19%
2) If 1000 kg/hr emission to soil:
* Air: 1.09%
* Water: 0.686%
* Soil: 98.2%
* Sediment: 0.0166%
3) If 1000 kg/hr emission to air:
* Air: 92.9%
* Water: 3.75%
* Soil: 3.21%
* Sediment: 0.0908%
Applicant's summary and conclusion
- Conclusions:
- According to the Fugacity model Level III ran with EpiSuite V4.1, the percentage that partitions to the soil, water and sediment compartments are greatly influenced by the emission scenario chosen. In the case of the registered substance none of the compartment must be seen as the preferred one because the substance is registered as an intermediate and no release may occur accordingly.
