Investigation of Outdoor/Indoor Air Quality During the Outbreak of COVID-19: A Review Study
European Journal of Sustainable Development Research, 2022, 6(1), em0180, https://doi.org/10.21601/ejosdr/11726
ABSTRACT: The 2019 novel coronavirus (COVID-19) pandemic has enormously affected the world and become a worldwide problem. To control the spread of COVID-19, human behaviors are generally controlled in most countries. However, exposure to air pollution causes increased susceptibility to COVID-19. The goal of this review research was to investigate the outdoor/indoor air quality during the outbreak of COVID-19. A review search was carried out from the databases Scopus, PubMed, Web of Knowledge, and Embase using the key words: “air quality” and “COVID-19 pandemic”. Twenty-four released articles were ultimately identified as eligible candidates for review study. The type of environment, country and city, type of study, goal of study, and study findings were analyzed. The results demonstrated the significant relationship between air pollution (PM2.5, PM10, SO2, NO2, CO, and O3) and the COVID-19 event. Indoor pollutant concentrations were typically higher during COVID-19 lockdown. There is also a relationship between meteorological parameters (rainfall, relative humidity, temperature, wind speed, and sunlight) and COVID-19 spread. The air quality index (AQI) of most countries improved to varying grades of quality under the COVID-19 infection control. It is crucial that policy makers and decision makers adopt more valuable methods to assist betterment of air pollution, particularly in developing nations, or control contact with pollutants so as to preserve public wellbeing.

Ventilation Systems and COVID-19 Spread: Evidence from a Systematic Review Study
European Journal of Sustainable Development Research, 2021, 5(2), em0158, https://doi.org/10.21601/ejosdr/10845
ABSTRACT: The main transmission mechanism of COVID-19 is through close contact, aerosols, droplets, and fomites transmission of the disease in closed spaces. In this study, the importance of ventilation in preventing the expansion of COVID-19 is reviewed. In total, 20 articles are reviewed. The obtained results show that ventilation has a crucial role in preventing COVID-19 expansion in indoor air environments. However, it should be used properly; otherwise, it will cause further expansion of the disease, as suggested for SARS. Appropriate ventilation can effectively prevent the expansion of COVID-19, and it will be more effective if be combined with particle filtration and air disinfection. The benefit of ventilation in highly polluted outdoor air conditions is an important field to be investigated in future studies. Finally, the results show that the six basic COVID-19 control strategies include: hand hygiene, social distancing, screening and case finding, isolation and separating, decontamination and disinfection, and effective ventilation. We hope that the results of the present study help researchers and health decision-makers in designing programs further perceive the importance of factors related to indoor conditions to control COVID-19 expansion.
