The impact of inhalable particulate matter exposure on daily mortality among residents in five typical cities in Inner Mongolia
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.
