Since the dawn of cities, built environment has both affected infectious disease transmission and evolved in response to diseases. COVID-19 illustrates dynamics. The pandemic presented an opportunity implement health promotion prevention strategies numerous elements environment.This commentary aims identify features that affect risk as well with implications for (and, therefore, long-term public health).Built factors include crowding, poverty, racism (as they manifest housing neighborhood features), poor indoor air circulation, ambient pollution. Potential changes building design, increased teleworking, reconfigured streets, changing modes travel, provision parks greenspace, population shifts out urban centers. Although it is too early predict confidence which these responses may persist, identifying monitoring them can help professionals, architects, planners, decision makers, members public, optimize healthy environments during after recovery from pandemic. https://doi.org/10.1289/EHP8888.

Impact of COVID-19 Pandemic on Air Quality: A Systematic Review

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(4), P. 1950 - 1950

Published: Feb. 10, 2022

With the emergence of COVID-19 pandemic, several governments imposed severe restrictions on socio-economic activities, putting most world population into a general lockdown in March 2020. Although scattered, studies this topic worldwide have rapidly emerged literature. Hence, systematic review aimed to identify and discuss scientifically validated literature that evaluated impact pandemic associated air quality. Thus, total 114 quantified quality through monitoring were selected from three databases. The countries India China; all intended evaluate quality, mainly concerning PM10, PM2.5, NO2, O3, CO, SO2. Most them focused 1st lockdown, comparing with pre- post-lockdown periods usually urban areas. Many conducted descriptive analysis, while others complemented it more advanced statistical analysis. using different methodologies, some reported temporary improvement during lockdown. More are still needed, lifting and, other areas, for definition better-targeted policies reduce pollution.

The Impact of COVID-19 Lockdowns on Air Quality—A Global Review

Sustainability, Journal Year: 2021, Volume and Issue: 13(18), P. 10212 - 10212

Published: Sept. 13, 2021

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

Changes of Air Pollutants in Urban Cities during the COVID-19 Lockdown-Sri Lanka

Aerosol and Air Quality Research, Journal Year: 2023, Volume and Issue: 23(3), P. 220223 - 220223

Published: Jan. 1, 2023

In response to the COVID-19 pandemic in early 2020, Sri Lanka underwent a nationwide lockdown that limited motor vehicle movement, industrial operations, and human activities. This study analyzes impact of on carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), sulfur (SO2), particulate matter (PM10, PM2.5) concentrations two urban cities (Colombo Kandy) Lanka, by comparison data from period (March May 2020) with its analogous 2019 2021. The results showed percentage change daytime PM10, PM2.5, CO, NO2 concentration during Colombo (Kandy) is –42.3% (–39.5%), –46% (–54.2%), –14.7% (–8.8%) –82.2% (–80.9%), respectively. both cities, was most sensitive. contrast, O3 has increased 6.7% (27.2%), suggesting increase mainly due reduction NOx emissions leading lower titration NO. addition, SO2 22.9%, while Kandy decreased –40%. During period, activities were significantly reduced, causing significant reductions operations transportation activities, further reducing improving air quality cities. this offer potential for local authorities better understand emission sources, assess effectiveness current pollution control strategies, form basis formulating environmental policies improve health.

Analysis and forecasting of air quality index based on satellite data

Inhalation Toxicology, Journal Year: 2023, Volume and Issue: 35(1-2), P. 24 - 39

Published: Jan. 5, 2023

The air quality index (AQI) forecasts are one of the most important aspects improving urban public health and enabling society to remain sustainable despite effects pollution. Pollution control organizations deploy ground stations collect information about pollutants. Establishing a station all-around is not feasible due cost involved. As an alternative, satellite-captured data can be utilized for AQI assessment. This study explores changes in during various COVID-19 lockdowns India utilizing satellite data. Furthermore, it addresses effectiveness state-of-the-art deep learning statistical approaches forecasting short-term AQI.Google Earth Engine (GEE) has been capture study. authenticated against beta distribution test before being incorporated into explored using like VAR, Holt-Winter, LSTM variants (stacked, bi-directional, vanilla).AQI ranged from 100 300, moderately polluted very poor period. maximum reduction was recorded complete lockdown period year 2020. Short-term with Holt-Winter more accurate than other models lowest MAPE scores.Based on our findings, pollution clearly threat studied locations, all stakeholders work together reduce it. level pollutants dropped substantially different lockdowns.
