ABSTRACT
Objective:
To further study concentration-response relationship between daily mortality and particulate air pollution,to provide scientific basis for making policy.Methods:
We applied spline model to daily time-series data for Taiyuan city,China from 2004-2005,using concentration of particulate matter less than 10 ?m in aerodynamic diameter(PM10)as the exposure measure,and controlling confounding factors,such as season,meteorological factors,day-of-the-week,other air pollutions,etc.Results:
The spline model showed a non-linear relationship for the relative risks of death for all causes(total deaths)and for specific causes in relation to PM10 concentration,and obtained threshold levels.For total mortality,malignant tumor mortality and cardiovascular-cerebrovascular-respiratory mortality,the threshold levels were 85.00 ?g/m3,89.59 ?g/m3,122.54 ?g/m3,respectively,using the value of differential deduction.Conclusion:
Our nonlinear models are appropriate for assessing the effect of particulate air pollution on daily mortality at current ambient levels in Taiyuan,China,in contrast to those of Europe and America.
