L'ozono, è una forma allotropica dell'ossigeno dalla formula chimica O3. È un gas blu dal caratteristico odore agliaceo che gli vale il nome: la parola "ozono" deriva infatti dal francese antico "ozone", la quale deriva a sua volta dal greco antico "ὄζειν" (ózein), cioè emanare odore. L'odore dell'ozono è rilevabile da molte persone a concentrazioni atmosferiche superiori a 0,1 ppm.
