BACKGROUND: The objective of the present study was to assess the smoking prevalence of workers, the attitudes toward smoking, and exposure to environmental @entity286 smoke (ETS) in different work environments. METHODS: A questionnaire survey and indoor air quality (IAQ) measurements including the concentration of gaseous @entity1239 in indoor air were performed in 10 medium-sized and large-scale workplaces representing industrial, service, and office environments. The questionnaire was distributed to all workers (n=1471) in 10 workplaces. IAQ measurements were performed in 4-7 locations in each workplace. RESULTS: Altogether 1027 (70%) employees, of whom 31% were @entity1 , responded to the questionnaire. Prevalence of daily smokers was 28.3% (32.3% for @entity1 and 22.9% for @entity1 ). The prevalence was highest among workers in the service sector (32.7%) and lowest in offices (21.6%). Among smokers, 86% of @entity1 and 75% of @entity1 smoked inside the building. Exposures greater than one hour to ETS were highest in industry (66.3%) and lowest in services (42.6%). Non-smokers complained more often than the regular smokers about the spreading of @entity286 smoke to non-smoking areas, and they felt that workplace smoking was a significant discomfort. Mean concentration of @entity1239 was highest in service environments (3.0 microg/m(3)) and lowest in offices (0.6 microg/m(3)). CONCLUSIONS: According to the present questionnaire survey and IAQ measurements, smoking habits and exposure to @entity286 smoke varied considerably depending on the position of the employees and the type of the workplace.
