“…For instance, Sharma et al ( 2020 ) reported that air quality has improved due to reduced emission levels of PM 2.5 , PM 10 , CO and NO 2 in 22 Indian cities during lockdown phase. Similarly, Velásquez and Lara ( 2020 ) applied a gaussian approach to determine the probability and correlation between COVID-19 cases and NO 2 concentration in Lima. Sicad et al ( 2020 ) studied the variation in NO 2 and O 3 concentration in four European cities and Wuhan during lockdown period.…”

In present study, the variation in concentration of key air pollutants such as PM 2.5 , PM 10 , NO 2 , SO 2 and O 3 during the pre-lockdown and post-lockdown phase has been investigated. In addition, the monthly concentration of air pollutants in March, April and May of 2020 is also compared with that of 2019 to unfold the effect of restricted emissions under similar meteorological conditions. To evaluate the global impact of COVID-19 on the air quality, ground-based data from 162 monitoring stations from 12 cities across the globe are analysed for the first time. The concentration of PM 2.5 , PM 10 and NO 2 were reduced by 20–34%, 24–47% and 32–64%, respectively, due to restriction on anthropogenic emission sources during lockdown. However, a lower reduction in SO 2 was observed due to functional power plants. O 3 concentration was found to be increased due to the declined emission of NO. Nevertheless, the achieved improvements were temporary as the pollution level has gone up again in cities where lockdown was lifted. The study might assist the environmentalist, government and policymakers to curb down the air pollution in future by implementing the strategic lockdowns at the pollution hotspots with minimal economic loss.

“…In order to study the relationship between pollution emissions, economic growth and number of deaths in India, a machine learning algorithm is used in [461] . A classification model based on Reduced-Space Gaussian Process Regression is proposed in [462] that studies the correlation between the number of covid-19 cases and air pollution.…”

“…Existen varios estudios que resaltan la correlación entre el aumento de concentración de ciertos contaminantes con la mortalidad por COVID-19, donde los infectados son propensos a enfermedades respiratorias crónicas (9,36,37) . Específicamente en relación a las altas concentraciones de NO2 (10,31,38) , como lo demostró Arias & Lara (39) , mediante una evaluación en Lima (Perú) donde las zonas industriales con más de 26 g/m 3 de NO2 pueden aumentar las infecciones por COVID-19. Asimismo, Wu et al (40) encontraron en Estados Unidos que al incrementar 1 ug/m 3 de PM2.5 aumenta la tasa de mortalidad por COVID-19 en un 8%, al mismo tiempo (41) corroboran el incremento de 13% a 21.4% en mortalidad.…”

La pandemia COVID-19 genera preocupación en todo el mundo, desde que el 30 de enero se declaró como emergencia de salud mundial (WHO), lo cual trajo consigo el cambio en el estilo de vida de la población, cierre de sistemas de transporte, paralización de actividades económicas, reduciendo las emisiones de contaminantes al ambiente, causando la mejora de la calidad del aire en muchas ciudades a nivel mundial. Hasta el momento, se han publicado varios estudios de revisión enfocados en los impactos ambientales por COVID-19, sin embargo, ninguno se enfoca específicamente en la contaminación del aire. Por lo cual, el objetivo principal fue presentar una revisión basada en un análisis integral de los estudios publicados abordando implicancias teóricas usadas dentro de los estudios. Se analizaron 68 estudios, los cuales se publicaron en 17 revistas hasta agosto del 2020. Además, se abordan posibles futuras investigaciones en relación al tema. Finalmente se exponen las conclusiones de la presente revisión.
