  1. Assessment of environmental tobacco smoke and respirable suspended particle exposures for nonsmokers in Basel by personal monitoring.

    Article - En anglais

    One hundred and ninety-six randomly selected nonsmoking subjects collected air samples close to their breathing zone by wearing personal monitors for 24 h. The study was centred in Basel, Switzerland, and comprised housewives in one group, primarily for assessing exposures in the home, and office workers in a second group to assess the contribution of the workplace to overall exposure.

    Samples collected were analysed for respirable suspended particles (RSP), nicotine, 3-ethenylpyridine and environmental tobacco smoke (ETS) particles by using ultraviolet absorbance, fluorescence and solanesol measurements.

    Saliva cotinine analyses were also undertaken to confirm the nonsmoking status of the subjects.

    Based upon median 24 h time weighted average concentrations, office workers who live and work with smokers were exposed to 39 mug/m3 RSP, 6.6 mug/m3 ETS particles and 0.90 mug/m3 nicotine.

    Housewives living with smokers were exposed to median concentrations of 34 mug/m3 RSP, 1.4 mug/m3 ETS particles and 0.60 mug/m3 nicotine.

    Workplaces where smoking occurred were estimated, on average, to contribute between 34 and 46% to annual exposure of ETS particles and nicotine.

    Based upon 90th percentile values the most highly exposed housewives, those living with smokers, would potentially inhale 18 cigarette equivalents per year whilst the most highly exposed office workers, both living and working with smokers, might inhale 61 cigarette equivalents. (...)
