A passive sampler was constructed and evaluated for determining nicotine, 3-ethenyl pyridine and Volatile Organic Compounds (VOCs) such as ethyl benzene and xylene in environmental tobacco smoke(ETS). ETS was collected on an adsorption disk, that is a glass fiber filter coated with XAD-4/PDMS A membrane filter was employed as a wind screen. Comparing the results obtained by active method, sampling rates for chemicals were determined. They were 38.0 ml/min for nicotine, 40.0 ml/min for 3-ethenyl pyridine 38.7 ml/min for ethyl benzene, 40.5 ml/min for p-xylene. However, our passive sampler was not satisfactory for benzene and toluene.
