The COVID-19 restrictions caused a shutdown of industrial and travel activities in 2020
to control the spread of the virus. Studies around the world have examined the impacts of
COVID-19 on ambient air pollution (Berman & Ebisu, 2020; Ghahremanloo, Lops, Choi,
Mousavinezhad, 2021; Ju, Oh, & Choi, 2021; Venter, Aunan, Chowdhury, & Lelieveld, 2020),
which all concluded a statistically significant reduction of air contaminants during the
COVID-19. However, no studies have focused on the impacts of international air travel
restrictions on the pollution levels during COVID-19. For our study, we examined whether the
decline in air travel during COVID-19 restrictions in Canada had a significant impact on local air
pollution. We analyzed PM2.5 concentrations from an air monitoring station at Vancouver
International Airport (YVR #2).
