Additional information

According to the estimated log Koc, MBTS has high adsorption potential in soil/sediment with the adsorption coefficient (log Koc) of 3.72 - 5.75 (Currenta, 2010). MBTS is essentially non-volatile with the estimated Henry's law constant H lower than 2.37 *10-8 hPa m3/mol at 25°C (Currenta, 2010) from aquatic media.

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%.

The transport and distribution characteristics of the potential metabolites of MBTS are also discussed in the relevant sub-chapters.
