The aim of this study is to explore the association between PM2.5 (particulate matter with aerodynamic diameter less than 2.5 ¦Ìm) and daily outpatient number for respiratory and cardiovascular diseases in a place where dust events are most frequent. During the study period, all hospitals in Wuwei, Gansu province, northwest of China were selected. The results suggest that there were associations between PM2.5 and the increasing of respiratory and cardiovascular diseases outpatient visits for males and females during the period when dust events frequently happen. PM2.5 was one of the main hazardous factors for these diseases during the study period.
