In Simulation, Moon Dust Found to Be Toxic to Humans
Apollo 16 LM Orion Wikimedia Commons Because we don't spend a large chunk of time up there, we haven't done too much research on the long-term health effects of living on the moon. But a paper titled "Toxicity of Lunar Dust," covering several aspects of the effects of moon dust on the human body, offers some insight: the moon is basically trying to kill you. Not actively, of course, but there are a lot of reasons to avoid the stuff (and no, a spacesuit isn't going to save you). The big problem is inhalation; even with a suit, dust can end up back in suit-free living spaces. Then the dust can travel inside travelers' lungs, causing inflammation and possibly, asbestos-style, even increasing the risk of developing cancer. The particles might be able to travel through the lungs more easily in the lower gravity environment, and exposure to UV and proton...
