[Passive smoking in bars, restaurants, and discotheques in Florence, Italy].
ABSTRACT "Environmental Tobacco Smoke (ETS) exposure in a sample of European cities" is the first European multicentre project intended to measure ETS exposure in public places in a number of European cities.
To present results of measurements of nicotine concentration in a number of bars, restaurants and discotheques in Florence, Italy.
The ETS marker was vapour-phase nicotine sampled by passive monitors. At least two monitors were placed in each of seven bars (five in hospitals; one at an airport; one at a railway station), and seven restaurants (three with smoking and non-smoking sections), and left in place for several days. In each of four discotheques two nicotine passive monitors were used as personal samplers.
The average nicotine concentration in discotheques, restaurants and bars was respectively 26.78 micro/m3, 2.32 microg/m3 and 0.83 microg/m3. In the smoking section of restaurants with separated areas for smokers and non-smokers the average nicotine concentration was 2.54 microg/m3, which was similar to that measured in non-smoking sections (2.14 microg/m3).
