Description of key information

For the components of this substance adsorption to the solid soil phase and suspended particles is expected. Therefore, low  mobility in soil can be assumed.

Key value for chemical safety assessment

Koc at 20 °C:
427 000

Additional information

The adsroption coefficient of this test material was determined by the HPLC method following the procedure in guideline OECD 121. The test material chromatogram showed peaks eluting between 23.374 and 29.947 minutes which, when normalized, correspond to 96.2% by area. Capacity factors for the eluted components were > 9.63. The capacity factors were correlated to logKoc values via a calibration plot of log K vs. log Koc generated from calibration standards.

The adsorption coefficient of the test material was determined to be > 4.27 x 105. The logKoc was calculated to be > 5.63.
