Additional information

The adsorption/desorption study has not been conducted as the substance can be expected to have a low potential for adsorption based on a log Kow of 2.67. The calculated Koc of 2 -methylbut-2 -ene is 183 based on a measured log Kow of 2.67 and following the Sabljic et al. (1995) method as set out in the Technical Guidance Document (ECB 2003).
