Key value for chemical safety assessment

Additional information

One study is available investigating the adsorption of the test substance Y-15866 (Weissenfeld, 2010). The study was performed according to OECD 121. The log of the adsorption coefficient (Koc) of Y-15866 was estimated based on Evaporative Light Scattering Detection (ELSD) and Ultra Violet (UV) detection to be between log Koc < 1.25 (equal to a Koc of < 18) and log Koc = 1.7 (equal to a Koc of 50.6) using the HPLC method. This value indicates a low potential for adsorption to organic carbon in sediment and soil. The mobility of Y-15866 can be classified to be high to very high based on the results of this experimental study.
