Description of key information

Adsorption to solid soil phase is not expected.

Key value for chemical safety assessment

Additional information

In soil, dimethyl ether - boron trifluoride reacts readily with the moisture to form dimethyl ether and boron trifluoride dihydrate. Dimethyl ether and boron trifluoride dihydrate are not readily biodegradable, but they have a low potential for adsorption. Dimethyl ether has a logKow of 0.13 - 0.26 (JETOC, 1991), indicating low adsorption potential. Boron trifluoride dihydrate, as well as its further hydrolysis products (e.g. boric acid, fluoroborates), are inorganic and have no cationic properties. Adsorption to the solid soil phase is therefore unlikely for all hydrolysis products.
