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 SO(2) and NO(2) were significantly associated with daily non-accidental and cardiovascular mortality but not associated with daily respiratory mortality. An increase of 10 µg/m(3) in SO(2) 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 10 µg/m(3) in NO(2) 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 SO(2) and NO(2) was significantly associated with daily cardiovascular and respiratory mortality in urban population in Tianjin.
