Abstract

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 (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) exposure and daily mortality.

Results: An increase of 10 μg/m3 of PM10 exposure and NO2 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 SO2 exposure and respiratory mortality at lag of 0 to 9 days.

Conclusions: Our findings strengthen the evidence of PM10 and NO2 exposures were independent risk for daily mortality.
