Objective To investigate the influence of exposure to inhalable particulate matter(PM10)on daily mortality among residents in five representative cities in central and western Inner Mongolia,and dentify sensitive populations and provide a basis for relevant departments to formulate air pollution prevention measures.Methods We collected daily meteorological data,air pollutant concentra-tions,and resident mortality data from five typical urban areas in Inner Mongolia from 2017 to 2021.Using a two-stage statistical analysis strategy(generalized additive model combined with meta-analysis),we constructed a time series model while controlling for confounding factors such as meteorological condi-tions and temporal trends.We assessed the effects of short-term exposure to atmospheric PM10 on popula-tion mortality.Results During the research period,the daily average concentration of PM10 in the atmosphere of five typical cities was(89.9±98.2)pg/m3,with a total of 126 401 deaths among resi-dents.Meta analysis showed that for every increase in PM10(lag0-2)exposure concentration 10 μg/m3,the non-accidental total mortality,male,female,and circulatory system disease mortality increased by 0.16％(95％CI:0.01％-0.36％),0.13％(95％CI:0.01％-0.25％),0.23％(95％CI:0.09％-0.37％)and0.21％(95％CI:0.08％-0.34％),respectively.Conclusions Short-term exposure to atmospheric particulate matter PM10 in five typical cities in Inner Mongolia increases the risk of non-accidentaltotal mortality and cardiovascular disease mortality among local residents.Women are more sensitive than men.The effect values vary slightly in different regions.
