When the Apollo astronauts returned from the Moon, the dust that clung to their spacesuits made their throats sore and their eyes water. Lunar dust is made of sharp, abrasive and nasty particles, but how toxic is it for humans?
Regolith is very sharp because it doesn’t have atmospheric forces to agitate it and cause the sort of erosion that makes things smooth. On top of that, no water means there’s nothing to ‘bind’ it like clay or mud; but also, as soon as it does touch water, it will want to stick.
Apparently moon dust became a significant problem for lunar excursions because it got everywhere
