title: [Time-series analysis of association between inhalable particulate matter and daily mortality among urban residents in Tianjin].
abstract: OBJECTIVE
  To study the association between particulate matter less than 10 micron in aerodynamic diameter (PM(10)) 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/m(3) in PM(10) 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.
  
  
  CONCLUSIONS
  Our findings indicated that the extent of exposure to PM(10) was significantly associated with daily mortality in urban population in Tianjin, especially with the mortality rates on circulatory and respiratory diseases.
