In the model MBTS 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 main target compartment for MBTS is soil with 41.34 % and sediment with 41.80 %, followed by water with 16.53% and suspended sediment with 0.27%.
Executive summary:

The distribution of MBTS in a "unit world" was calculated according to the Mackay fugacity model level I (Currenta, 2010) based on the physico-chemical properties. The main target compartment for MBTS is soil with 41.34 % and sediment with 41.80 %, followed by water with 16.53% and suspended sediment with 0.27%.
