Chlorofluorocarbons Measurement in the Lower Atmosphere of the Antarctica

Data concerning chlorofluorocarbons and other halogenated hydrocarbons concentrations in ground-level atmosphere at Antarctica are reported. Measurements were carried out during two campaigns: Austral summer 1989/90 and 1990/91. Samples collected were analyzed in the laboratory by gas chromatography-mass spectrometry and “in situ” by gas chromatography-electron capture detection. Substantial improvements in the instrumentation are also reported where for what trapping and injection of both air samples and calibration mixtures are concerne
