Abstract:
Objective To study the association between particulate matter less than 10 micron in aerodynamic diameter (PM10) and daily mortality among urban population in Tianjin.Methods We collected data of air quality, daily mean temperature and relative humidity, and daily cause-specific death counts, and used generalized additive models to explore the relationship between ambient particulate matter and daily mortality, after adjusting the effects of long-term and seasonal trend, weather conditions and other gaseous pollutants, such as sulfur dioxide and nitrogen dioxide.Results An increase of 10 μg/m3 in PM10 was associated with 0.45% (95%CI: 0.21-0.69) non-accidental morality, 0.60% (0.29-0.91) circulatory morality and 0.82% (0.04-1.61) respiratory morality, respectively. Conclusion Our findings indicated that the extent of exposure to PM10 was significantly associated with daily mortality in urban population in Tianjin, especially with the mortality rates on circulatory and respiratory diseases.
