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 19 89/90 and 1990/91. Samples collected were analyzed in the laboratory b y gas chromatography-mass spectrometry and ''in situ'' by gas chromato graphy-electron capture detection. Substantial improvements in the ins trumentation are also reported where for what trapping and injection o f both air samples and calibration mixtures are concerned.
