Description of key information

1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas (boiling point -26°C) and has a low potential for adsorption (log Kow 1.06); it is expected that direct and indirect exposure of the sediment compartment is therefore unlikely.

Key value for chemical safety assessment

Additional information

In accordance with column 2 of REACH Annex IX and X, the study on sediment toxicity does not need to be conducted as 1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas (boiling point -26°C) and has a low potential for adsorption (log Kow 1.06); it is expected that direct and indirect exposure of the sediment compartment is therefore unlikely.
