Spatiotemporal variable selection and air quality impact assessment of COVID-19 lockdown

Alessandro Fasso et al.

Summary: This paper examines the impact of lockdown measures on air quality in the Lombardy Region of Italy. The study finds significant reductions in nitrogen dioxide concentrations in metropolitan areas and near trafficked roads during the lockdown period, along with a corresponding decrease in PM10 concentrations. However, rural, industrial, and mountain areas did not show significant reductions, and there was no significant decrease in PM2.5 concentrations regardless of the zone.

Urban-Rural Disparities in Air Quality Responses to Traffic Changes in a Megacity of China Revealed Using Machine Learning

Yifan Wen et al.

Summary: Assessing the disparities of urban-rural air quality response to changes in emissions is important for developing effective air pollution mitigation strategies. A machine learning-based air quality simulator was established, which showed high accuracy in reproducing pollutant concentrations and revealed similar meteorological impacts but different effects from traffic activities on air quality between urban and rural areas.

Non-linear response of PM2.5 to changes in NOx and NH3 emissions in the Po basin (Italy): consequences for air quality plans

Philippe Thunis et al.

Summary: The study focuses on the Po basin in Europe, analyzing the sensitivity of PM2.5 concentration to NOx and NH3 emissions, finding that reduction in NOx emissions in NOx-rich areas may lead to a slight increase in PM2.5 levels. This process could have contributed to the absence of a significant decrease in PM2.5 concentration during the COVID-19 lockdowns in many European cities.
