The determination of the adsorption coefficient (KOC) of test item was performed according to the OECD 121 method. The test item was not retained under the chromatographic conditions of the test and was eluted at the dead time. The KOC of the test item was therefore determined to be lower than that one of the lowest reference item used (acetanilide). The chromatography of the test item resulted in one main peak with a well-defined and reproducible retention time. The HPLC method was therefore considered to be suitable for the purpose of the study. Based on the chromatographic data, the test item was considered to be stable during the test procedure. In conclusion, the log of the adsorption coefficient (KOC) of test item was estimated to be log KOC <1.25 which is equal to a KOC value of < 18using the HPLC method. This value indicates that the test item will not be adsorbed by organic carbon in soil.
