Is osmium safe to touch?
Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10-7 g m-3 can cause lung congestion, skin damage, and severe eye damage. The oxide, in particular, should only ever be handled by a properly qualified chemist.
Is osmium poisonous?
Osmium tetroxide is highly poisonous. Exposure to osmium tetroxide may cause harm to the skin, eyes, and respiratory system. Workers may be harmed from exposure to osmium tetroxide. The level of exposure depends upon the dose, duration, and work being done.
Is osmium rarer than gold?

Can you eat osmium?
Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide, at room temperature. Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature. Eating/Drinking – Accidental ingestion of the compound itself can lead to adverse health effects.
