Abstract
The aim of the study is to assess the relationship between PM2.5, synoptic weather patterns, and admissions for circulatory and respiratory disease. A PM2.5 event is defined as a day when the daily mean PM2.5 concentration exceeds 65 μg/m3. PM2.5 events that coincided with the occurrence of PM attributed to Asian dust storm (ADS) and photochemical smog (PCS) were removed from the study in order to focus solely on the health effects from PM2.5. A one-tailed z-test and a relative risk (RR) estimate were performed. Hospital admissions for respiratory diseases were greater than those for circulatory diseases, and asthma-related diseases had a higher impact in the Adults group, and the maximum RR was 1.94 [1.37 2.77] on the first day after the event. It is evident that PM2.5 episodes connected to particular synoptic weather patterns pose a risk to health as large as ADS and PCS events.
