AbstractGlobal microplastic (MP) pollution is now well recognized, with humans and animals consuming and inhaling MPs on a daily basis. Herein we described the effects of azide-free, 1 um polystyrene MP beads co-delivered into lungs with a SARS-CoV-2 omicron BA.5 inoculum using a mouse model of mild COVID-19. Lung virus titres and viral RNA levels were not significantly affected by MPs, with overt clinical or histopathological changes also not observed.
