Effects of Coronavirus Induced City Lockdown on PM2.5 and Gaseous Pollutant Concentrations in Bangkok

Racha Dejchanchaiwong et al.

Summary: The study investigated the effects of partial lockdown measures on air quality in Bangkok, specifically focusing on PM2.5 and gas concentrations. While some pollutant concentrations were higher before the lockdown, the changes in PM2.5 levels during the lockdown were influenced by both local sources and external factors, such as transboundary aerosol transport from biomass burning. Reducing Bangkok's air pollution requires addressing various sources, including improving equipment for sugarcane harvesting to reduce biomass burning, implementing stricter emission control standards for diesel engines, and coordinating efforts among ASEAN member countries to address transboundary haze.
