The long-distance spreading and transport of airborne particulate matter PM of biogenic or chemical compounds, which are thought to be possible carriers of SARS-CoV-2 virions, can have a negative impact on the incidence and severity of COVID viral disease.
Through descriptive statistics analysis applied to average daily time series in situ and satellite data of PM2.
Exposure to high levels of PM2. The derived average PM2. The findings of this research are important for decision-makers implementing COVID safety controls and health measures during viral infections. Surveillance of viral disease outbreaks and the influx of data on the evolution of viruses and other pathogenic microorganisms highlight the need for in-depth investigation and severe measures to mitigate the potential transmission of airborne viruses and pathogens, particularly through outdoor particulate matter contaminants.
The recent coronavirus disease COVID pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 SARS-CoV-2 and its mutations, and known as the third human disease outbreak of the 21st century is responsible for more than 68, deaths and more than 3,, infected people from 26 February to 20 August in Romania. Bucharest, the capital of Romania, recorded about Due to the hydrophobic properties of the SARS-CoV-2 spike protein, COVID viral respiratory infection is believed to be transmitted mainly through the inhalation of virus-laden respiratory droplets [ 2 , 3 ], airborne diffusion [ 4 , 5 , 6 ], direct contact with infected persons, fomites, feco-oral routes [ 7 ], or the incineration of COVID sewage sludge and recovery of residue ash as building material [ 8 , 9 ].
The relative importance of different viral transmission routes is variable in different spatio-temporal climates and topographic and socioeconomic conditions. Several scientific studies considered international trade indicators and complex human-to-human interactions to be more important pathways than demographic, pollution, and economic aspects that must be used to describe the transmission of COVID dynamics in different countries [ 10 , 11 , 12 ].
