Abstract:
Two cases of lethal poisoning due to chlorodifluoromethane (Freon 22) inhalation are described. The fluorocarbon was determined in biological tissues by headspace gas chromatography/mass spectrometry. Ions monitored were m/z 67, 86 and 51, the latter being used for quantification. Blood concentrations were 26.0 and 37.1 microliters/ml. In both cases, the drug was also identified in urine, vitreous humor and bile, but in much lower concentrations.
