Any other information on results incl. tables
As all releases in both manufacturing and use will be into the air, the model was based on 100 % emission to air.

- Executive summary:
HFC-143a will partition almost entirely into the air
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
