TL;DR: The complex and nonlinear response of chemical compositions and sources of PM2.5 to air pollution control measures are highlighted, suggesting the importance of regional-joint control.

TL;DR: The COVID-19 lockdown reduced PM2.5 and increased visibility in Wuhan as mentioned in this paper, which was the first lockdown in the history of the city's air quality monitoring system.

TL;DR: The significantly enriched fungal taxa in the night-sample group (29 taxa) were also much more than that in the day- sample group (9 taxa), which could explain the higher species richness of airborne fungi community in theNight during the haze evolution episodes.

TL;DR: Wang et al. as discussed by the authors investigated the impact of meteorology and emission changes on surface ozone variations in different regions in the summer of 2022 by an explainable machine learning method and found that the changes in emissions dominated the surface ozone enhancement in the Pearl River Delta (PRD), Beijing-Tianjin-Hebei (BTH), and Twain-Hu Basin (THB) with contributions of 89, 86, and 53% respectively.

TL;DR: Based on the online monitoring data of fine particle (PM2.5) mass concentration, carbonaceous components, ionic constituents, and elemental components in an urban site of Wuhan from December 2019 to November 2020, the chemical characteristics of PM 2.5 were analyzed.
