Based upon a calculated log Koc adsorption to solid soil phase is not expected.
A calculated logKoc of 0.079 is available (BASF AG, SRC PCKOC v1.66,
2007). This value refers to the uncharged molecule (pKa value: 4.87).
This pKa value indicates that the molecule will exist primarily as an
anion. Hence, the value calculated by the PCKOC-model requires a
recalculation based on the environmentally relevant pH values to take
into account the ionic structure of the molecule. Under environmental
conditions (pH from 5 to 9) the test substance is almost completely
present in its charged form at the pH values of 7 and 9 and 57% of the
molecule are present in its charged form at a pH of 5 (calculated using
the formula % ionised = 100/(1+10(pKa - pH)). In a calculation conducted
according to a publication by Franco & Trapp, 2008 using the parameters
pKa = 4.87 and log Pow = 0.58 log Koc values for the pH values 5, 7 and
9 were determined to be 1.54, 1.6 and 1.6, respectively.
