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.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
