Description of key information
In a study conducted according to OECD Guideline 106 soil sorption coefficients (Koc) from 781 (log Koc= 1.6) to 1505 (log Koc=4.3), depending on the soil type, were obtained. Based on these results and taking into account the classification of McCall et al, the test item mobility is low. Therefore, and with regard to the instability of the test item in aqueous environment, the desorption was not determined. The test item shows linear Freundlich adsorption with typical 1/n values between 0.7 and 1 in all soils except for LUFA 2.4. In this soil, a steady decrease in the mass balances was observed over the tested concentration range indicating that at least a slight test item degradation took place inconcurrence to the adsorption. This fact is in accordance to the values for the inverse regressionconstants 1/n > 1, indicating a significant nonlinear adsorption behaviour.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
