“…Data from countries in the European Economic Area (EEA) show that the concentration of NO2 emitted mainly by road transport has decreased in many European cities where containment measures have been taken (EEA, 2020). A significant reduction in the concentration of pollutants has also been found in many regions of the world, indicating that isolation measures have a positive effect on air quality (Broomandi et al, 2020;Ginzburg et al, 2020;Jephcote et al, 2020;Liu et al, 2020;Zangari et al, 2020;Anil and Alagha, 2021;Islam et al, 2021;Sbai et al, 2021). In particular, measurements carried out at 129 monitoring stations located in the United Kingdom revealed average reductions in PM2.5 by -16.5% and NO2 by -38.3% (Jephcote et al, 2020).…”

“…The favorable effects of the COVID-19 lockdown have led to significant reductions in atmospheric pollution in various countries across the world, such as China (Filonchyk et al, 2020b;Liu et al, 2020;, India (Mahato et al, 2020;Siddiqui et al, 2020;Singh et al, 2020), Ecuador (Pacheco et al, 2020), Saudi Arabia (Anil et al, 2020), Spain (Baldasano, 2020), Iran (Broomandi et al, 2020), Russia (Ginzburg et al, 2020), France (Sbai et al, 2021), Bangladesh (Islam et al, 2021), United Kingdom (Jephcote et al, 2020). The improvements in air quality have been caused by significant reductions in the number of anthropogenic pollutants such as restrictions on road traffic and industrial activities during the COVID-19 pandemic.…”

Since its first detection in December 2019 in the Chinese city of Wuhan, the virus has become a global pandemic within just three months. The Polish government declared a state of emergency on March 14, 2020, which was connected with the adoption of a number of measures aimed to prevent the spread of the virus. These restrictive measures have led to improvements in air quality throughout the country. Therefore, evaluation of the reduction in anthropogenic emissions due to COVID-19 and related government measures to constrain its spread is crucial to define its impact on air pollution. During this study, aerosol optical depth (AOD) observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) were used along with tropospheric NO2 and SO2 vertical column densities from TROPOspheric Monitoring Instrument (TROPOMI). The data on ground-based concentrations of pollutants (PM2.5, PM10, NO2 and SO2) obtained from air quality monitoring stations were also considered to assess changes in aerosols and air pollutants connected with the cessation of various kinds of anthropogenic and industrial activities due to preventive measures for COVID-19. In large cities of the country, the concentrations of PM2.5, PM10 and NO2 were reduced in the range from -5.1% to -35.5%, from -8.3% to -33.1% and from -0.4% to -18.8%. In addition, satellite data for NO2 and SO2 also indicate a decrease in concentration across the country by -10.8% and -25.6% during the COVID-19 restrictions period. The lockdown events may play a vital role as a potential solution to reduce air pollution in future as it may not be uncommon for governments to introduce deliberately selective hotspot lockdowns to control pollution levels.

“…In central Europe, the NO, NO 2 , and CO concentrations and the total number of particles with diameters <100 nm decreased by 68, 46, 27, and 28% in 2020 relative to the (2017–2019) average reference [ 6 ]. Based on data of work [ 7 ], the level of the main pollutants in the atmosphere decreased by 30–50% in Moscow in the period of restrictive measures.…”

We present information on ozone concentration in the surface air layer in the second half of 2020. Data were obtained at 13 stations located in different regions of Russia. We estimated the excess over hygienic standards of the Russian Federation, both in the second half of the year and throughout 2020. It is shown that the daily average maximum permissible concentration of ozone is regularly exceeded at all stations. There are cases of exceeding the one-time maximum permissible concentration.

“…At their peak, emissions in individual countries decreased by -26% on average. The impact on 2020 annual emissions depends on the duration of the confinement, with a low estimate of -4% (-2 to -7%) if pre-pandemic conditions return by mid-June, and a high estimate of -7% (-3 to -13%) [137].

The outbreak of the COVID-19 pandemic has emerged as a serious public health threat and has had a tremendous impact on all spheres of the environment. The air quality across the world improved because of COVID-19 lockdowns. Since the outbreak of COVID-19, large numbers of studies have been carried out on the impact of lockdowns on air quality around the world, but no studies have been carried out on the systematic review on the impact of lockdowns on air quality. This study aims to systematically assess the bibliographic review on the impact of lockdowns on air quality around the globe. A total of 237 studies were identified after rigorous review, and 144 studies met the criteria for the review. The literature was surveyed from Scopus, Google Scholar, PubMed, Web of Science, and the Google search engine. The results reveal that (i) most of the studies were carried out on Asia (about 65%), followed by Europe (18%), North America (6%), South America (5%), and Africa (3%); (ii) in the case of countries, the highest number of studies was performed on India (29%), followed by China (23%), the U.S. (5%), the U.K. (4%), and Italy; (iii) more than 60% of the studies included NO2 for study, followed by PM2.5 (about 50%), PM10, SO2, and CO; (iv) most of the studies were published by Science of the Total Environment (29%), followed by Aerosol and Air Quality Research (23%), Air Quality, Atmosphere & Health (9%), and Environmental Pollution (5%); (v) the studies reveal that there were significant improvements in air quality during lockdowns in comparison with previous time periods. Thus, this diversified study conducted on the impact of lockdowns on air quality will surely assist in identifying any gaps, as it outlines the insights of the current scientific research.
