HFC 125 is released only in the atmosphere during its manufacture and use.

Due to the high Henry's Law Constant and to the predicted low adsorption potential, HFC 125 is expected to distribute mainly in the atmospheric compartment following its emission into the environment.

The environmental distribution of HFC 125 was estimated be means of the Fugacity Model Level III (2002), under the assumption that 100% release occurs in air. The Level III model’s results indicated that HFC 125 would partition mainly into the air compartment (~100%) and less than 0.001% and 0.004% in water and soil compartments, respectively.
