In this study, we aimed to determine the effects of outdoor air pollution on patients with moderate asthma. 24 patients who used standard therapy in the treatment of asthma, aged 18-51, had undertaken this study and had been followed for two months between November 1996 and May 199?. Daily respiratory symptoms at night and day and taking rescue medication for asthma were recorded daily by using daily symptom cards (over a period of two months) for this period. Outdoor average S0-2 concentration was found 66.8 ppb (SD 48.6) and PM concentration was 97.4 ppb (SD 48.8) for the period from November 1996 to May 1997. Exposure effect curves have also been found for both SO-2 and PM between symptoms and taking rescue medication. When the levels of SO-2 or PM were higher than 100 ppb increase in rescue medication (17%) an exacerbation of symptoms in days (12%) was observed (p0.05). But there was not any significant increase in symptoms at night (4%) (p0.05), that shows that the asthmatic patients were also affected from air pollution at below concentrations.
