Due to the estimated logKocs binding to solid soil phase is possible.
pKa value of the substance indicates that the molecule will exist
primarily as a cation in the environment and cations generally adsorb
stronger to soils containing organic carbon and clay than their neutral
counterparts. Hence, the KOCWIN-model may underestimate adsorption to
organic carbon since it does not consider the ionic structure of the
molecule. Under environmental conditions (pH from 5 to 9) the test
substance is mostly present in its charged form (as calculated by the
formula% ionised = 100/(1+10(pKa - pH)). In a calculation conducted
according to a publication by Franco & Trapp (2008) taking into account
a pKa of 8.5 and logPow of 1.64 logKoc values between 3 and 4 were
