Study design
- Test substance input data:
- - Molar mass: 350.08
- Data temperature: 20-25 °C
- Water solubility: 0.295 mg/L
- Vapour pressure: 46.9 mmHg
- log Pow: 4.3
- Organic carbon adjusted soil - water partition coefficient: 6500 L/kg
- Melting point: -67 °C
- Reaction half-life estimates for
- Air: 2.3e+04 hr
- Water: 1e+08 hr
- Soil: 1e+08 hr
- Sediment: 1e+08 hr
Degradation half-lives were set to very long but non-infinite values to avoid model instability. Emissions were permuted to varying combinations of air, water and soil at the unrealistic rate of 1 tonne/hour (cf. <100 tonnes/year as registered). Only values for the three individual emission cases are reported here.

Any other information on results incl. tables
It should be noted that the majority of the annual volume of HFE s-601 is used in stationary heat transfer systems. Releases to soil or water are expected to be rare. As indicated by model results for 100% release to air, essentially all HFE s-601 will remain in the atmospheric compartment if released to air.
The model in EPI Suite is a direct adaptation of EQC model developed by Mackay and co-workers. While it uses the same equations and exactly the same default values as the stand-alone application, it was adapted specifically for use in EPI Suite. The Episuite implementation is notable for ease of use and is frequently utilized in regulatory contexts. However, the model is often incompletely parameterized, and as a result physical-chemical property estimates from other Episuite modules are used to parameterize the fugacity model. The use of estimated physical-chemical properties, rather than experimental values, leads to unrepresentative fugacity model outputs. The results presented in this study summary are based on full fugacity model parameterization with dossier data and are to be used in preference to a basic model run.
Applicant's summary and conclusion
- Conclusions:
- HFE s-601 will remain in the atmospheric compartment if released to the air. Distribution to soil, water, or sediment are expected to be negligible.
- Executive summary:
Distribution modeling was done using the Mackay level III fugacity module within Episuite v.4.11. The model was parameterized as completely as possible using data from the technical dossier. HFE s-601 will remain in the atmospheric compartment if released to the air. Distribution to soil, water, or sediment are expected to be negligible. The model is limited in terms of its ability to predict distribution of volatile and insoluble substances, but is frequently used in regulatory settings to provide an initial estimate of fate until more sophisticated models such as NewEQC are run. The calculation method is therefore deemed to be acceptable and the result is considered reliable with restrictions.
