This study reports the mortality burden due to PM exposure among adults (age >25) living in Hanoi in 2017. We applied a health impact assessment methodology with the global exposure mortality model and a PM map with 3 × 3 km resolution derived from multiple data sources. The annual average PM concentration for each grid ranged from 22.1 to 37.2 µg/m³. The district average concentration values ranged from 26.9 to 37.2 µg/m³, which means that none of the 30 districts had annual average values below the Vietnam Ambient National Standard of 25 µg/m . Using the Vietnam Ambient National Standard as the reference standard, we estimated that 2,696 deaths (95% CI: 2,225 to 3,158) per year were attributable to exposure to elevated PM concentrations in Hanoi. Using the Interim Target 4 value of 10 µg/m as the reference standard, the number of excess deaths attributable to elevated PM exposure was 4,760 (95% CI: 3,958-5,534). : A significant proportion of deaths in Hanoi could be avoided by reducing air pollution concentrations to a level consistent with the Vietnam Ambient National Standard.
