Description of key information

The substance has low adsorption potential and therefore is considered as very mobile in soil and sediment.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

In the absence of an experimental adsorption coefficient, the Koc value can be estimated with a QSAR method. The method proposed by Gerstl (1990) is considered appropriate for the estimation. The estimation equation log Koc = 0.679 · log Kow + 0.663 is based on a large and diverse data set of experimental Koc values. The resulting log Koc value is 1.991 and the Koc = 97.9. According to the classification scheme of McCall (1981) the substance is very mobily in soil and sediment.
