Air pollution rebound and different recovery modes during the period of easing COVID-19 restrictions.

ABSTRACT: Although COVID-19 lockdown policies have improved air quality in numerous countries, there is a lack of empirical evidence on the extent to which recovery has resulted in air pollution rebound, and the differences and similarities among regions' recovery modes during the period of easing COVID-19 restrictions. Here, we used daily air quality data and the recovery index constructed by a city-pair inflow index for 119 cities in China to quantify the impact of recovery on air pollution from March 2 to October 30, 2020. Findings show that recovery has significantly increased air pollution. When the recovery level increased by 10 %, the concentration of PM_2.5, SO₂, and NO₂ respectively deteriorated by 1.10, 0.33, 1.25 μg/m³, and the average growth rat
