Adsorption to solid soil phase is expected

Key value for chemical safety assessment

Additional information

In a GLP study performed according to OECD-guideline no. 106 (1984) on 3 common European soils, adsorption of > 95% in all three soils where determined. Desorption was low, ranging from 1-8% of the applied substance (depending on the type of soil). The Koc values determined in the advanced adsorption test were between 7673 and 18432, the Freundlich isotherm parameter Koc ranged from 2018 to 3311 pg ai / g soil, respectively (NATEC 1995, for CIBA).
