Description of key information

The determination of the adsorption coefficient (KOC) of read across substance FAT 40827/A was performed according to the OECD Guideline for the Testing of Chemicals, No. 121, Estimation of the Adsorption Coefficient (KOC) on Soil and Sewage Sludge using High Performance Liquid Chromatography (HPLC), January, 2001 and the EC Directive 2001/59, C.19. The log of the adsorption coefficient (KOC) of FAT 40827/A was estimated to be log KOC <1.25 which is equal to a Koc value of <18 using HPLC method. This value indicates that FAT 40827/A will not be adsorbed by organic carbon in soil. Based on this data for similar substance, the target test substance can be classified to be of very high mobility.
