Additional information

The study was performed using a HPLC with a cyanopropyl chemical bound resin on a silica base column. Six reference items with different retention times were used to produce a calibration curve, since retention time on cyanopropyl columns and Koc are correlated.

The mean value was ca. -5.6. Since this value is outside the range of the method as given in the guidelines, the log Koc of the test item is stated as < 1.5.
