HFC 227ea is released only in the atmosphere
during its manufacture and use.
Due to the high vapor pressure and to the
predicted low adsorption potential, HFC 227ea is expected to distribute
mainly in the atmsopheric compartment following its emission into the
A low adsorption potential to soil and sediment
is expected in view of the low octanol-water partition coefficient odf HFC
The environmental distribution of
HFC227ea was estimated be means of the Fugacity Model Level I (2002),
under the assumption that 100% release occurs in air. The Level III
model’s results indicated that HFC 227ea would partition mainly into the
air compartment (100%) and less than 0.02%in water. No partitioning expected
in soil and sediments.
