Using our patented Combined Remediation Biomass and Bio-Product Production (CRBBP) Process, our Maryland operating affiliate, ATP-MD, LLC (ATP-MD), proposed a multi-faceted, Project, in Baltimore, Maryland, to, among many other things, capture flue gas CO 2, from power plants and other large CO 2 emitters, to remediate brownfield sites, in neighborhoods, and also capture substantial amounts of airborne particulate matter, which is especially important, these days, as the residents of communities impacted by this type of air pollution, suffer from asthma and other respiratory diseases and, therefore disproportionately suffer from coronavirus illnesses to a much higher and much more severe extent.
The following research indicates that plants are able to filter airborne particulate matter:

Also, the following research suggests that airborne particulate matter may, in fact, be a COVID-19 vector:
