Abstract

Air pollution has garnered widespread concern for its detrimental effects on human health. This study aims to investigate the spatiotemporal dynamics of air pollution in Northeast China from 2019 to 2023 from a health perspective. Focusing on 36 cities, this study analyzed the pollution characteristics and health hazards of PM_2.5, PM₁₀, SO₂, CO, NO₂, and O₃. The findings indicate that the annual average concentrations of air pollutants did not exceed the limit values. Except for O₃, the concentrations of pollutants showed a downward trend year by year, while O₃ exhibited an opposite trend. The overall spatial pollution level was Liaoning>Jilin>Heilongjiang. The air quality in various cities was predominantly categorized as 'Good' and ' Moderate'. Based on the USEtox model, it is estimated that PM contributes to an average of 3174.66 premature deaths annually, with a mortality rate of 0.11%. This translates to an estimated 1103.60 premature deaths per million people each year. The calculation of the Hazard Quotient (HQ) for pollutants suggests that they do not pose a health risk to the population.
