If they're "ultrafine particles" you'd think they'd just blow around once the cover was removed think dust in a sunbeam. My father has a lung disease called IPF (terminal) which is scarring of the lungs it occurs over time from various particles. He was a blue collar worker exposed to various fine particles; sawdust, welding fumes, grinding metal, paint, probably some asbestos insulation etc. at his place work over the decades which caused small amounts of damage each year. Lungs are not to be messed with they're so delicate and lung cancer isn't the worst fatal lung disease you can get.
