Description of key information

The adsorption / desorption behaviour of bis(4-fluorophenyl) ketone was studied with the batch equilibrium method according to OECD guideline 106 (2000) and SEPA guideline 106 (2004). The Freundlich adsorption coefficients Kd for bis(4-fluorophenyl) ketone on tree soil types are 26.4 (Heitu), 18.2 (Zongrang) and 16.4 (Sand), respectively. Referring to the organic matter contents of 1.74, 6.67 and 1.27 % this leads to 1517 (Heitu), 272 (Zongrang) and 1291 (sand). The geometric mean is 810.
