Response to comments by Mage regarding 'Is daily mortality associated specifically with fine particles?'

摘要

Dear Editor, We are somewhat puzzled to receive a comment on a paper two decades old, focused on the exposure error due to missing days of particle concentrations, particularly when many subsequent papers, some involving over 100 cities, have examined the association of PM_(2.5) with daily deaths. Those studies had daily mon itoring data available, and found similar results. For example, Dai et al. (2014) examined 75 U.S. cities and reported a 1.18% increase in daily deaths associated with a 10 μg/m~3 increase in PM_(2.5), quite similar to our earlier report Moreover, if the issue is error in assigning exposure, great progress has been made by combining daily monitoring data with daily satellite remote sensing data. Using this approach Kloog et al. (2013) recently reported an association between two-day mean exposure at each decedent's home address and the risk of death, again with similar effect size to our two-decade-old paper.
