Abstract:
Objective:To make a quantitative evaluation on the short term effect of particulate matter with aerodynamic diameter no more than 2.5 μm (PM2.5) on cumulative excess mortality rate (CER) and years of life lost (YLL) in residents in Changping district of Beijing.
Methods:The death data in local residents, daily mortality, meteorology data and air pollution data (PM2.5, SO2 and NO2 concentrations) in Changping from 2014 to 2017 were collected. Distributed lag non-linear model was used to assess the age and gender specific cumulative lag effects of PM2.5 on cardiovascular CER and daily YLL in Changping.
Results:The effects of PM2.5 on cardiovascular CER and YLL were obvious on lag 7 days and lag 9 days, respectively, peaking on day 14, and lasting for 21 days. On lag0-21 days, for a 10 μg/m3 increase in PM2.5, the population based CER of cardiovascular disease death was 0.021% (95%CI: 0.004%-0.038%), and the YLL was 1.47 (95%CI: 0.23-2.70) years. Greater PM2.5 effect were observed in males and the elderly.
Conclusion:PM2.5 increased the risk of cardiovascular disease death and YLL.
