Impact of Long—term Exposure to Air Particulate Matter on Life Expectancy and Survival Rate of Shanghai Residents
摘要
To evaluate the impact of long-term air particulate matter exposure on the life expectancy and survival rate of Shanghai residents.Methods Epidemiology-based exposure-response function was used for the calculation of attributable deaths to air particulate matter in Shanghai,and the effect of long-term exposure to particulate matter on life expectancy and survival rate was estimated using the life table of Shanghai residents in 1999.Results It was shown that in1999,the long-term air particulate matter exposure caused1.34-1.69years reduction of life expectancy and a decrease of survival rate for each age group of Shanghai residents.Conclusion The effect of long-term exposure to air particulate matter on life expectancy is substantial in Shanghai.
