自1976年以来，芬兰《烟草法》一直限制在公共场所吸烟，1994年对该法进行了修订，将工作场所也包括在内。2000年，《烟草法》将进一步扩大到餐馆。在芬兰，客户和员工暴露在餐厅的气相环境烟草烟雾(ETS)中之前没有通过测量室内空气中的ETS标记物进行过系统的研究。然而，在这些机构中，ETS的浓度预计会比其他工作场所高得多。在三种不同类型的餐馆中，使用气态尼古丁和9-乙烯基吡啶作为ETS指示剂。尼古丁的平均浓度为1.4-42.2mU/m(3)，9-乙烯基吡啶的平均浓度为1.4-6.3mU/m(3)。总挥发性有机化合物(TVOC)、CO和CO2的浓度分别为183-2215 mg/m(3)、0.9-3.1 mg/m(3)和600-880ppm。ETS标志物的浓度以迪斯科舞厅和夜总会最高，餐馆最低。迪斯科舞厅和夜总会的总挥发性有机化合物浓度最高，特别是在使用烟雾发生器的情况下。
The Finnish Tobacco Act has restricted smoking in public places since 1976, and in 1994 the Act was amended to include workplaces as well. In 2000, the Tobacco Act will be expanded further to restaurants. In Finland, the exposure of clients and employees to the vapor phase environmental tobacco smoke (ETS) in restaurants has not been systematically studied before by measuring ETS markers in indoor air. However, in these establishments the concentrations of ETS are expected to be much higher than in other workplaces. Gaseous nicotine and 9-ethenyl-pyridine were used as indicators of ETS in three different types of restaurants. Mean concentrations of nicotine ranged from 1.4- 42.2 mu g/m(3) and 9-ethenylpyridine 1.4-6.3 mu g/m(3). In addition, concentrations of total volatile organic compounds (TVOC), CO and CO2 were measured and concentrations were 183-2215 mu g/ m(3), 0.9-3.1 mg/m(3) and 600-880 ppm, respectively. The concentrations of ETS markers were highest in discos and nightclubs and lowest in restaurants. The concentrations of total volatile organic compounds were highest in discos and nightclubs, especially when smoke generators were used.
