Description of key information

The substance has a calculated log Koc of 7.876. Therefore, adsorption to solid soil phase is expected.

Key value for chemical safety assessment

Additional information

The Koc and log Koc was calculated using a QSAR (BASF SE Department of Product Safety 2012) according to the Technical Guidance Document Part III of the European Chemicals Bureau: QSARs for soil and sediment sorption for different chemical classes (Sablijc and Güsten, 1995). The model is based on linear regression analysis and log Kow as descriptor variable. It should be noted that all models are developed assuming an equilibrium state. The influence of Kow is logical because hydrophobic interactions are the most dominant type of interactions between non-polar organic chemicals and the soil organic carbon. The result of log Koc = 7.876 reveals that adsorption to the solid soil phase is expected.
