Noxious is an adjective for substances or situations that are harmful, poisonous, or seriously disturbing to health or well being. In everyday English, it often describes gases, chemicals, smells, or ideas and actions that pose immediate risk or cause damage. The word carries a stronger sense than simply dangerous, implying toxicity or air you should avoid. Its origin comes from nox- meaning harm with -ious meaning having the quality of, tracing from Latin noxius through Old French to English. Imagine a toxic gas seeping into a room, making the air unlivable and pushing you to leave quickly.
