Assessment of air quality in barcelona by personal monitoring of nonsmokers for respirable suspended particles and environmental tobacco smoke

摘要

presonal monitoring over a 24-h period was performed using over 190 subjects divided into two distinct groups, one for housewives and one for office workers. Questionnaire surveys were con- ducted in addition to determinations for respirable suspended particles (RSP), environmental tobacco smoke (ETS) particles, nictine, 3-ethenylpyridine, and saliva cotinine. The highest median levels of RSP, ETS particles, and nicotine were measured for subjects working in smoking workplaces. However, workers living in smoking households were more exposed outside working hours since More time was sent outside the workplace.
