Reduction of air pollutants and associated mortality during and after the COVID-19 lockdown in China: Impacts and implications.

ABSTRACT: Although strict lockdown measurements implemented during the COVID-19 pandemic have dramatically reduced the anthropogenic-based emissions, changes in air quality and its health impacts remain unclear in China. We comprehensively described air pollution during and after the lockdown periods in 2020 compared with 2018-2019, and estimated the mortality burden indicated by the number of deaths and years of life lost (YLL) related to the air pollution changes. The mean air quality index (AQI), PM₁₀, PM_2.5, NO₂, SO₂ and CO concentrations during the lockdown across China declined by 18.2 (21.2%), 27.0 μg/m³ (28.9%), 10.5 μg/m³ (18.3%), 8.4 μg/m³ (44.2%), 13.1 μg/m³ (38.8%), and 0.3 mg/m³ (27.3%) re
