The changes in global air pollutant concentrations influenced by the COVID-19 lockdown have been widely investigated. lack of clarity regarding individual contributions to restricted human activities (i.e., transportation) has limited understanding health impacts lockdown. In this study, an efficient chemical transport model (GEOS-Chem) was employed simulate concentration pollutants (PM 2.5 , NO 2 and O 3 ) associated with emission reductions land transportation corresponding benefits. simulated results suggested that transportation-related PM reduced 20%, 36%, 55%, respectively. reduction presented regional variations, percentages ranked as follows: China (67%) > India (56%) Europe (−81%) US (−86%), indicating various intensities secondary transformations spatial relevance. benefits were also simulated, all-caused mortalities estimated be 63,547 (95% CI: 47,597, 79,497), 52,685 32,310, 73,059), 231,980 210,373, 253,586) for globally, Transportation-related contributed largest proportion (∼67%) benefits, further emphasizing relevance severity pollution. Our study confirms during considerable provides relevant data supporting evidence. We suggest coordinated efforts restrict certain worldwide should focus on controlling protect people from severe exposure.
