Ethylene (C2H4)

Ethylene is a colourless, flammable gas with a sweet odour and the chemical formula C2H4. It is a naturally occurring plant hormone and an important industrial chemical used in producing plastics (like polyethene), antifreeze, and other chemicals.

Ethylene health effects:

Ethylene is generally considered to have low acute toxicity, but at high concentrations, it can act as an asphyxiant by displacing oxygen in the air. Prolonged exposure to ethylene oxide, a derivative, poses significant health risks, including respiratory irritation and potential carcinogenic effects.
