Additional information

According to the interpretation from Swann (Swann et al. 1983), MBT has moderate adsorption potential in soil/sediment with the adsorption coefficient (log Koc) of 2.51- 3.55 (CMA, 1989). MBT is essentially not volatile with the Henry's law constant H lower than 3.6*10-6 hPa m3/mol at 25°C (Currenta, 2010) from aquatic media according to the criteria of Thomas (1990). The distribution calculation (Mackay level I) showed that the main target compartment for MBT is water with 95.96 %, followed by soil with 2.00 % and sediment 2.02 % (Currenta, 2010). The transport and distribution characteristics of the described metabolites of MBT are also discussed in the relevant sub-chapters.
