Abstract
THE chlorofluorocarbon CCl3F (trichlorofluoromethane) occurs in the atmosphere1, and seems especially attractive for use as a tracer of air and water mass movements2,3. Its use as a propellant-solvent for aerosol dispensers results in its entry to the atmosphere where, due to its stability, it can accumulate. There has been an exponential increase in the use of this compound in recent years. Its residence time in the atmosphere has been estimated to be greater than ten years3.
