Content | 0297 Edition 1/2010 617.0-IFA:638.1 Exposure to environmental tobacco smoke in German hospitality venues Problem Before the introduction of statutory protection for non-smokers, employees in the catering sector in Germany were exposed to tobacco smoke. The new legislation also provides for exemptions from a complete smoking ban. Since little in the way of published data is available on the exposure of employees in German hospi- tality venues, a study conducted jointly by the IPA and IFA was to present the scale of this exposure. Activities Tobacco smoke comprises over 4,000 different substances, approximately 70 of which are car- cinogenic. Owing to the smoke s complex compo- sition, nicotine was selected as a tobacco-specific substance, and acrylonitrile for evaluation of the exposure to environmental tobacco smoke. At the IFA, methods were developed and validated for measuring nicotine and acrylonitrile in envi- ronmental tobacco smoke. The internal exposure of the test subjects was determined by the IPA, by measurement of nicotine and its metabolic prod- ucts in the urine and saliva and of a haemoglobin adduct of acrylonitrile in the blood. In the summer of 2008, a total of 134 stationary (at the bar/counter) and personal samples were taken for 37 non-smoking employees in eleven hospital- ity venues in Bochum and Cologne (café/bistro: 44; pub/bar: 68; discotheque: 22). Tobacco smoke Sampling was conducted in most cases from the evening through to the early morning hours, and also during the morning in cafés/bistros. The sta- tionary measurements were repeated in eight smoking hospitality venues in the winter of 2008/2009. Results and Application Nicotine and acrylonitrile were detected in all air samples. In the summer, the concentrations for nicotine lay between 1.2 and 152 µg/m³, and for acrylonitrile between 0.1 and 8.2 µg/m³, with a close correlation between the two. The highest exposures were found in disco- theques (nicotine: 19.5 to 152 µg/m³; acrylonitrile: 1.9 to 8.2 µg/m³), the lowest in cafés/bistros |
