Spatiotemporal impact of COVID-19 on Taiwan air quality in the absence of a lockdown: Influence of urban public transportation use and meteorological conditions

Concentration and size distribution of atmospheric particles in southern Italy during COVID-19 lockdown period

“…Second, a site-dependent effect existed because the observatory is located in the university campus, which maintained a high level of smart working during the POST-LD period analysed herein. This is in agreement with the results found by Wong et al (2022) in which an improvement of air quality was observed also in absence of a lockdown period. Third, during LD the reduction of pollution emissions due to transportation, consequence of the “stay-at-home” restrictions, was partly compensated by an increase of biomass burning emission for domestic heating.…”

Peculiar weather patterns effects on air pollution and COVID-19 spread in Tokyo metropolis

“…Also, a clear finding of this study highlights the lack of adopted lockdown or other traffic and travel restrictions for air pollution control during the 7th COVID-19 in Tokyo, which possible could limited viral disease spreading ( Wong et al, 2022 ; Chen et al, 2021 ; Chinazzi et al, 2020 ).…”

Implications of the Improvement in Atmospheric Fine Particles: A Case Study of COVID-19 Pandemic in Northern Taiwan

“…Hence, traffic-related emission (Factor 1), especially for the carbonaceous matter, should be a vital role to deal with. This also implied that cleaner energy for vehicles is needed in the future to reduce traffic-related emission (Wong et al, 2022).…”
