Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely

Description of key information

The substance is gaseous and the primary environmental compartment to which it partition is air. In accordance with column 2 of REACH Annex IX, the study must not be conducted if exposure to soil and sediment is unlikely.

Key value for chemical safety assessment

Additional information

The substance is a gas and considering its solubility, volatility and resultant Henry’s Law Constant, 2,3,3,3-Tetrafluoropropene is expected, under equilibrium conditions, to exist principally in the air.Additionally, the substance is not expected to adsorb to soil based upon the log Koc. Therefore atmosphere is the main target environmental compartment. In the air the substance degrades through indirect photolysis. As such it is unlikely that the substance reach concentrations in soil, at which any effects have to be expected. In accordance with column 2 of REACH Annex IX, the study must not be conducted if exposure to soil and sediment is unlikely.The equilibrium partitioning method has been used to assess the hazard potential of, 2,3,3,3-Tetrafluoropropene for soil organisms.
