Emission Sector Impacts on Air Quality and Public Health in China From 2010 to 2020.

ABSTRACT: Anthropogenic emissions and ambient fine particulate matter (PM_2.5) concentrations have declined in recent years across China. However, PM_2.5 exposure remains high, ozone (O₃) exposure is increasing, and the public health impacts are substantial. We used emulators to explore how emission changes (averaged per sector over all species) have contributed to changes in air quality and public health in China over 2010-2020. We show that PM_2.5 exposure peaked in 2012 at 52.8 μg m^-3, with contributions of 31% from industry and 22% from residential emissions. In 2020, PM_2.5 exposure declined by 36% to 33.5 μg m^-3, where the contributions from industry and residential sources reduced to 15% and 17%, respectively. The PM
