Web17 apr. 2024 · Hydrogen sulfide is a gas that naturally occurs in the environment in crude petroleum, natural gas, volcanic gases and hot springs. Hydrogen sulfide is heavier than air, so it stays low to the ground. People can smell the specific odor at low concentrations in air ranging from 0.0005 to 0.3 parts per million (ppm). WebAir is a mixture of gases, mostly nitrogen and oxygen 78.1% nitrogen 20.9% oxygen 0.9% argon 0.1% other gases (like carbon dioxide) Air is well mixed, so we do not usually talk about oxygen being lighter or heavier than air. Helium, on the other hand, is much lighter than air (nitrogen and oxygen), so that is why a helium-filled balloon goes up.
