Abstract:
Environmental tobacco smoke exposure of human subjects in different public houses was evaluated. The levels of airborne nicotine from environmental tobacco smoke and changes in urinary cotinine and nicotine levels between smoking and non-smoking subjects were compared. A gas chromatography-mass spectrometric (GC-MS) quantitative method for nicotine and cotinine levels in the indoor air and in urine was developed. A Thermo Quest Trace DSQ GC-MS equipped with a Rtx-5MS capillary column, 15m 0.25mm, 0.25 m film thickness, was used in a temperature programme starting from 50°C, for 2min, then increased at 8°C·min -1 to 250°C and held for 10min. The method was validated and gave good linearity, precision, accuracy and limit of detection. A significant correlation between urinary cotinine increase and airborne nicotine is presented.
