Adsorption/ desorption

The soil adsorption coefficient (Koc) was calculated using EPI Suite KOCWIN v2.00 program. Using the molecular connectivity index (MCI) method the Koc was calculated to be 10.88 L/kg and log Koc to be 1.0368 respectively. Using the Kow method the Koc was calculated to be 38.09 L/kg and Log Koc to be 1.5808 respectively. The calculated log Koc using the log Pow method was regarded as most reliable because this value based on a measured log Pow of the substance. The Koc of 38.09 L/kg was regarded as worst case assumption. Adsorption to solid soil phase is not expected.

Furthermore, the substance can be expected to have a low potential for adsorption due to its low log Kow value of 1.60 as well as the substance and its relevant degradation products decompose rapidly.
