Critical supply chains for mitigating PM2.5 emission-related mortalities in India

Abstract Air pollution and its health-related effects are a major concern globally, and many people die from air pollution-related diseases each year. This study employed a structural path analysis combined with a health impact inventory database analysis to estimate the number of consumption-based...
