As air pollution can travel long distance, change in emissions from one region influence air quality and associated premature mortality over others. This research uses ensemble-modeled concentrations of anthropogenic ozone (O3) and fine particulate matter (PM2.5) to quantify avoided premature mortality from 20% emission reductions of 6 regions (i.e. North America (NAM), Europe (EUR), South Asia (SAS), East Asia (EAS), Russia/Belarus/Ukraine (RBU) and the Middle East (MDE)) and 3 sectors (i.e. Power and Industry (PIN), Ground Transportation (TRN) and Residential (RES)) and evaluate the impact of interregional transport of precursor emissions from local (i.e. Kao-Ping air basin (KPAB)) and upwind air basin regions (i.e. North and Chu-Miao Air Basin (NCMAB), Central Air Basin (CTAB), Yun-Chia-Nan Air Basin (YCNAB), and Yi-Lan and Hua-Dong Air Basin (YLHDAB)) on O3 and PM2.5 air quality over KPAB. For health impact assessment, we estimate 290,000 (95% CI: 30,000, 600,000) premature O3-related deaths and 2.8 million (0.5 million, 4.6 million) PM2.5-related premature deaths globally for the baseline year 2010. Reducing emissions from MDE and RBU can avoid more O3-related deaths outside of these regions than within while reducing MDE emissions also avoids more PM2.5-related deaths outside of MDE than within. TRN emissions account for the greatest fraction (26-53% of global emission reduction) of O3-related premature deaths in most regions, except for EAS (58%) and RBU (38%) where PIN emissions dominate. For air quality impact assessment, anthropogenic emissions from upwind and local emissions can contribute 17% and 7% of daily maximum 8-hour O3 concentrations, respectively on the highest O3 day while 36.8% and 26.6% of 24-hour average PM2.5 concentrations, respectively during the high PM2.5 days over KPAB, indicating that the upwind emissions play a significant role in KPAB O3 and PM2.5 concentration. The most effective emission control strategy can be approached by reducing upwind anthropogenic NOX emission along with local VOC emission for O3 while upwind anthropogenic NOX emission along with local primary PM2.5 emission for PM2.5. The result highlights the importance of long-range air pollution transport and suggests that emission reductions can improve air quality and have associated health benefits downwind. Therefore, regional cooperation to reduce air pollution transported over long distances may be desirable.
