Description of key information

Additional information
The soil adsorption coefficient of Benzenesulfonic acid, di-C10-14-alkyl derivs., calcium salts was determined by the computer program KOCWIN v2.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2013). This tool estimates the organic carbon-normalized sorption 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 of 15.75 (Koc: 5.64E+15 L/kg) and the MCI method reveals a comparable value of 15.65 (Koc: 1E+10 L/kg) as result. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
[LogKoc: 15.65]
