Description of key information

In accordance with column 2 of REACH Annex IX and X, the study on sediment toxicity does not need to be conducted as the substance is a gas and has a low potential for adsorption (log Kow 1.21); it is expected that direct and indirect exposure of the sediment compartment is therefore unlikely.

Key value for chemical safety assessment

Additional information

The log Kow value of 1.21 suggests that any TFE released into water is not expected to adsorb to sediment or suspended solids. Therefore it is expected that direct and indirect exposure of the sediment compartment is unlikely.
