The Short-Term Effects of Ambient Air Pollutants are Associated With Daily Mortality in Northeast China From 2014 to 2018

Objective: We aimed to examine the associations between ambient air pollutants and daily mortality in Northeast China from 2014 to 2018. Methods: A two-stage approach was used to estimate particulate matter with an aerodynamic diameter of 10 μm (PM 10 ), nitrogen dioxide (NO 2 ), and sulfur dioxide (SO 2 ) exposure and daily mortality. Results: An increase of 10 μg/m 3 of PM 10 exposure and NO 2 at lag of 0 to16 days was associated with the cumulative relative risk of 1.011 (95% confidence interval [CI]: 1.004, 1.019) and 1.026 (95% CI: 1.004, 1.049), respectively, in non-accident mortality. Meanwhile, significant association was observed in people aged under 60 years between SO 2 exposure and respiratory mortality at lag of 0 to 9 days. Conclusions: Our findings strengthen the evidence of PM 10 and NO 2 exposures were independent risk for daily mortality.
