Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China

Xin Huang et al.

Summary: The study indicates that during the COVID lockdown, haze was mainly driven by enhanced secondary pollution, particularly due to the significant decrease in NOx emissions from transportation. This highlights the need for a coordinated and balanced strategy to control multiple pollutants for haze mitigation.

A wide-ranging investigation of the COVID-19 lockdown effects on the atmospheric composition in various Italian urban sites (AER - LOCUS)

M. Campanelli et al.

Summary: The study examines the impact of the first COVID-19 lockdown on the atmospheric composition in five Italian urban sites, revealing a general decrease in PM10, PM2.5, BC, NO2, and benzene concentrations during the lockdown period. After removing the long-range transport contributions, significant reductions in PM10 and PM2.5 concentrations are found in the northern sites.

Air quality changes in cities during the COVID-19 lockdown: A critical review

Max G. Adam et al.

Summary: In 2020, governments worldwide introduced unprecedented measures in response to COVID-19, which had an impact on atmospheric pollutants. While reductions in outdoor air pollutants such as particulate matter and nitrogen dioxide were observed during lockdowns, the levels of ozone and secondary PM were reported to remain unchanged or even increase.

A global observational analysis to understand changes in air quality during exceptionally low anthropogenic emission conditions

Ranjeet S. Sokhi et al.

Summary: This study, coordinated by the WMO/GAW programme, aims to understand the behavior of key air pollutants during the COVID-19 pandemic period. The analysis focuses on changes in air quality in cities across the globe, with decreases observed in NO2 and NOx concentrations correlating with reduced mobility. However, complex signals suggest that sources other than vehicular emissions significantly contributed to the changes in air quality.

Global Changes in Secondary Atmospheric Pollutants During the 2020 COVID-19 Pandemic

Benjamin Gaubert et al.

Summary: During the COVID-19 pandemic, global reductions in primary pollutants (NOx, VOCs, CO, SO2) led to increases in secondary pollutants in NOx-saturated areas and decreases in NOx-limited areas. The response of the chemical system depended on changes in NOx and VOC emissions, and was influenced by weather variability, which could lead to anomalies in chemical species concentrations.

Response of atmospheric composition to COVID-19 lockdown measures during spring in the Paris region (France)

Jean-Eudes Petit et al.

Summary: The COVID-19 pandemic and subsequent lockdowns led to significant reductions in atmospheric pollutant emissions, impacting air quality. An innovative Analog Application for Air Quality (A(3)Q) method was developed to evaluate the impact of lockdown measures on air quality, revealing substantial decreases in primary traffic pollutants while also characterizing changes in secondary pollutants. These findings provide valuable insights for future mitigation policies in urban areas aiming to improve air quality.

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.

Summary: The COVID-19 lockdown measures in northern Italy resulted in a significant decrease in NO2 concentrations by 30% - 40% on average, while PM10 concentrations remained relatively unaffected. The lockdown also led to an increase in O-3 concentrations, and after the lockdown was lifted, there was a significant increase in PM10 concentrations compared to expected levels.
