At environmentally relevant pH and 25°C the logKoc of MBS is determined
as 2.84. Due to hydrolysis, the adsorption coefficients of the
degradation products (e. g. MBT, BT and morpholine) are relevant for
risk assessment of MBS in the environment. MBT and BT have a moderate
adsorption potential in soil/sediment with the adsorption coefficient
(log Koc) of 2.51 – 3.55 and 3.0, respectively. Morpholine however has
only a low affinity to adsorption with a logKoc of 0.867. MBS is
essentially non-volatile with the calculated Henry's law constant lower
than 5.52*10-7 Pa m3/mol at 25°C. The distribution of MBS 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 MBS is water of 71.3 % and sediment of 14.32 %, followed by soil of
