phosphine
Flammable hydrogen compound
Phosphine is a colorless, highly toxic gas with a distinctive garlic or rotting fish odor, composed of phosphorus and hydrogen.
It occurs naturally from decomposing organic matter and has industrial uses in semiconductor manufacturing and fumigation.
The detection of phosphine in planetary atmospheres, notably Venus, has prompted speculation about possible biological origins, since living organisms produce it on Earth.
