Description of key information


The soil adsorption coefficient of benzene mono-C10-13-alkyl derivatives, distillation residues, sulfonated, sodium salts was determined by the computer program KOCWIN v2.00 (EPIWIN software v4.11) by US-EPA (ATL, 2016). This tool estimates the organic carbon-normalized adsorption coefficient for soil (and also for sediment), which is designated as Koc. Two different models are used for this estimation: the Sabljic molecular connectivity (MCI) method as well as with the traditional method which is based on logPow. The traditional method gives a logKoc ranging from 3.558 to 5.522 and the MCI method reveals a comparable value ranging from 5.1 to 6.86 as result. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
