Description of key information

1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas (boiling point -26°C) of low solubility and is expected to quickly disappear from the aquatic phase. Therefore, any impact on the aquatic environment is expected to be low.

Key value for chemical safety assessment

Additional information

1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas (boiling point -26°C) of low solubility and is expected to quickly disappear from the aquatic phase. Therefore, any impact on the aquatic environment is expected to be low. These mitigating factors indicate that aquatic toxicity is unlikely to occur, and a long-term toxicity study on fish will be inappropriate in accordance with REACH Annex IX 9.1 Column 2.
