Abstract
The world has been exposed to the Coronavirus Disease 2019 (COVID-19) since late 2019. A global pandemic has shifted health concerns from air pollution effects to novel coronavirus disease, similarly to those in Bangkok. Although Bangkokians have experienced severe PM2.5 conditions since the last quarter of 2017, the related agencies have failed to elucidate the crisis. This has been because the fundamental air quality management is focused on controlling emissions. The Thai government has sluggishly determined the situations that lead to the inability to clean up its air. How are air pollution and disease linked? This article points to the importance of source management. The lockdown measures revealed reduced traffic rate and PM2.5 concentrations. Such a close relationship has shed insights of the consequences of working from home (WFH). The link between disease and air pollution includes (i) WFH regulation is one specific way to prevent the transmission of disease, (ii) this guideline decreases traffic congestion in an urban city which is one path of diminished pollution discharge and (iii) then noticeably followed by PM2.5 reductions. Again, the magnitude of source control is crucial. Reducing pollutions from traffic by means of WFH has illustrated this accomplishment. In the midst of this crisis, moving to a new normal role supports remaining protected from both air pollution and the pandemic. Nevertheless, the sustainability of transportation control in an overcrowded city like Bangkok should be considered as a vital pathway to tackle air pollution.
