A new approach to evaluate regional inequity determined by PM_2.5 emissions and concentrations.

ABSTRACT: PM_2.5 is one of the most severe types of air pollution that threatens human health. Its emissions have a notable spillover effect once released into the atmosphere and transported. In domestic trade, PM_2.5 emissions can be indirectly imported from external regions. Thus, regional inequity caused by PM_2.5 needs to be integrated and comprehensively estimated. Based on PM_2.5 emissions/concentrations grid maps and an input-output model, this study first examined the temporal-spatial changes in PM_2.5 emissions/concentrations across China. Additionally, a detailed relationship between PM_2.5 emissions and concentrations was examined at multiple scales, both temporal and spatial. Finally, this study developed a new approach with whi
