The authors report on GC-MS measurements of HCFC-142b and HCFC-141b in gas samples collected since 1978, to look at changes in the background levels since the switch toward HCFC type compounds as replacements for CFC compounds has been legislated. The samples show marked increases in the concentrations of these compounds beginning to appear in the time period around 1990, in addition to getting a background level measurement for the compounds.
