In the model TBBS is treated as a type 1 chemical, i.e. the chemical partitions into all environmental media.Estimation is carried at an environmental temperature of 25 °C.

Applicant's summary and conclusion

Conclusions:
The distribution of TBBS in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for TBBS is water of 72.65 %, followed by sediment of 13.31 % and soil of 13.16 %.
