Abstract:
Objective To study the associations between daily mortality and the status of exposure to air pollution.Methods A time-series analysis was conducted to assess the relations between acute mortality and exposure to respiratory particulate matter (PM10),sulfur-dioxide (SO2) and nitrogen dioxide (NO2) in urban residents of Guangzhou (2004-2008),using Poisson regression.Results Through controling the factors as temperature,relative humidity,age,gender and time,significant increases were observed in all-cause mortality of 0.94％ (0.79-1.09) for PM10,1.55％(1.31-1.78) for NO2,and 1.09％ (0.91-1.27) for SO2,per 10 μg/m3,when increase of the lagging 2-day average concentrations of air pollution was seen,in Guangzhou.Stronger effects of exposure to air pollution were found on cardiovascular and respiratory mortality,as well as in elderly( ≥65 years) and female population.Conclusion Our results suggested that exposure to ambient pollution was significantly associated with the increase of excess risks,on total and cardio-respiratory mortality in the residents of Guangzhou.
