The data on daily hospitalization for respiratory diseases from the biggest hospital in the city were extracted. The generalized additive models (GAM) and the distributed lag non-linear model (DLNM) were employed to evaluate the association between ambient SO<jats:sub>2<\/jats:sub> and daily inpatient visits for respiratory diseases.

In addition, SO<jats:sub>2<\/jats:sub> had a stronger association with respiratory inpatient visits in women, older adults (\u226565 years), and warmer season (May-Oct) subgroups. The relationship between SO<jats:sub>2<\/jats:sub> and inpatient visits for respiratory diseases was robust after adjusting for other air pollutants, including PM<jats:sub>10<\/jats:sub>, NO<jats:sub>2<\/jats:sub>, O<jats:sub>3<\/jats:sub>, and CO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This time-series study showed that there is a positive association between short-term SO<jats:sub>2<\/jats:sub> exposure and daily respiratory inpatient visits.
