“…In order to assess the relationship between the total confirmed cases of COVID-19 in Victoria (Mexico), and the levels of PM 2.5 , PM 10 and CO, as well as meteorological factors (relative humidity, temperature, and absolute humidity), Tello-Leal and Macías-Hernández (2021) carried out a Pearson correlation analysis with air quality data covering from February 16, 2020 to June 6, 2020, and those related to the cases of COVID-19 covered from March 23, 2020 to June 6, 2020. It was found that the cases of COVID-19 were strongly associated with CO concentrations, whereas the levels of PM 2.5 and PM 10 showed also a significant correlation for confirmed cases of COVID-19.…”

In June 2020, we published a review focused on assessing the influence of various air pollutants on the transmission of SARS-CoV-2, and the severity of COVID-19 in patients infected by the coronavirus. The results of most of those reviewed studies suggested that chronic exposure to certain air pollutants might lead to more severe and lethal forms of COVID-19, as well as delays/complications in the recovery of the patients. Since then, a notable number of studies on this topic have been published, including also various reviews. Given the importance of this issue, we have updated the information published since our previous review. Taking together the previous results and those of most investigations now reviewed, we have concluded that there is a significant association between chronic exposure to various outdoor air pollutants: PM 2.5 , PM 10 , O 3 , NO 2 , SO 2 and CO, and the incidence/risk of COVID-19 cases, as well as the severity/mortality of the disease. Unfortunately, studies on the potential influence of other important air pollutants such as VOCs, dioxins and furans, or metals, are not available in the scientific literature. In relation to the influence of outdoor air pollutants on the transmission of SARS-CoV-2, although the scientific evidence is much more limited, some studies point to PM 2.5 and PM 10 as potential airborne transmitters of the virus. Anyhow, it is clear that environmental air pollution plays an important negative role in COVID-19, increasing its incidence and mortality.

“…Previous studies (as shown in Table S1 ) critically investigated lockdown effects toward concentrations of air pollutants ( Abdullah et al., 2020 ; Nakada and Urban, 2020 ; Tanzer-Gruener et al., 2020 ; Tobías et al., 2020 ; Venter et al., 2021 ; Yuan et al., 2021 ); air pollution relationship with COVID-19 cases ( Accarino et al., 2021 ; Tello-Leal and Macías-Hernández, 2020 ); meteorology and air pollutants changes ( Hossain et al., 2021 ; Sulaymon et al., 2021 ); traffic and mobility changes ( Aloi et al., 2020 ); and the application of statistical and modelling ( Bao and Zhang, 2020 ; He et al., 2020 ; Liu et al., 2020b ) while this study focuses mainly on air pollutants effects in cities with the analysis related to population exposure to non-carcinogenic risks. The COVID-19 pandemic affected human activities, primarily when the MCO was implemented to reduce the chain of infection among the population in Malaysia.…”

“…Dunker et al and Chirizzi et al observed negative results for the presence of SARS-CoV-2 in outdoor air samples ( Dunker et al, 2021 , Chirizzi et al, 2021 ). Dogan et al and Tello-leal et al showed a negative correlation between the number of infected individuals and temperature, and they found that PM 2.5 , and PM 10 have a significant positive correlation with positive cases of COVID-19 ( Tello-Leal and Macías-Hernández, 2020 , Doğan et al, 2020 ). Zoran et al demonstrated that the COVID-19 outbreak in Milan coincided with a positive association with air temperature and negative association with air relative humidity, because dry air increases the viral diffusion ( Zoran et al, 2020 ).…”

The limited knowledge about the mechanism of SARS-CoV-2 transmission is a current challenge on a global scale. Among possible transmission routes, air transfer of the virus is thought to be prominent. To investigate this further, measurements were conducted at Razi hospital in Ahvaz, Iran, which was selected to treat COVID-19 severe cases in the Khuzestan province. Passive and active sampling methods were employed and compared with regard to their efficiency for collection of airborne SARS-COV-2 virus particles. Fifty one indoor air samples were collected in two areas, with distances of less than or equal to 1 m (patient room) and more than 3 m away (hallway and nurse station) from patient beds. A simulation method was used to obtain the virus load released by a regularly breathing or coughing individual including a range of microdroplet emissions. Using real-time reverse transcription polymerase chain reaction (RT-PCR), 11.76% (N=6) of all indoor air samples (N=51) collected in the COVID-19 ward tested positive for SARS-CoV-2 virus, including 4 cases in patient rooms and 2 cases in the hallway. Also, 5 of the 6 positive cases were confirmed using active sampling methods with only 1 based on passive sampling. The results support airborne transmission of SARS-CoV-2 bioaerosols in indoor air. Multivariate analysis showed that among 15 parameters studied, the highest correlations with PCR results were obtained for temperature, relative humidity, PM levels, and presence of an air cleaner.
