Lunar dust (LD), the component of lunar regolith with particle sizes less than 20 μm, covers the surface of the Moon. Due to its fineness, jagged edges, and electrostatic charge, LD adheres to and coats almost any surface it contacts. As a result, LD poses known risks to the proper functioning of electronic and mechanical equipment on the lunar surface. However, its mechanical irritancy and chemical reactivity may also pose serious health risks to humans by a number of mechanisms. While Apollo astronauts reported mild short-lived respiratory symptoms, the spectrum of health effects associated with high-dose acute exposure or chronic low-dose exposure are not yet well-understood. This paper explores known and potential human risks of exposure to LD which are thought to be important in planning upcoming lunar missions and planetary surface work.
月尘（LD）是粒径小于20微米的月壤成分，覆盖在月球表面。由于其细度、锯齿状边缘和静电荷，月尘会附着并覆盖几乎任何它接触到的表面。因此，月尘对月球表面电子和机械设备的正常运行构成了已知风险。然而，其机械刺激性和化学反应性也可能通过多种机制对人类健康造成严重风险。虽然阿波罗宇航员报告了轻微的短期呼吸道症状，但与高剂量急性暴露或慢性低剂量暴露相关的健康影响范围尚未得到充分了解。本文探讨了已知的和潜在的月尘暴露对人类的风险，这些风险在规划未来的月球任务和行星表面工作中被认为是重要的。
