Abstract:
Objective To study the association between sulphur dioxide, nitrogen dioxide and daily mortality in urban population from Tianjin. Methods Data on daily concentration of inhalable particulate matter, sulphur dioxide and nitrogen dioxide, daily mean temperature and relative humidity, daily cause-specific death counts were collected. Generalized additive models was used to explore the relationship between sulphur dioxide, nitrogen dioxide and daily mortality, after adjusting the effects of long-term and seasonal trend, weather conditions, and to analyze the potential effect of particulate matter and model parameters on relative risk estimates. Results Results showed that the daily concentrations of SO2 and NO2 were significantly associated with daily non-accidental and cardiovascular mortality but not associated with daily respiratory mortality. An increase of 10 μg/m3 in SO2 was associated with 0.56%(95%CI: 0.23%-0.89%)non-accidental morality, 0.49%(0.06%-0.93%)cardiovascular morality, respectively. An increase of 10μg/m3 in NO2 was associated with 0.94%(95% CI: 0.17%- 1.70%)non-accidental morality, 1.29%(0.29%-2.30%)cardiovascular morality, respectively. Conclusion Our findings suggested that exposure to SO2 and NO2 was significantly associated with daily cardiovascular and respiratory mortality in urban population in Tianjin.
