Diyokiside ya azote (NO₂) ikomoka ahanini ku gutwika ibicanwa mu binyabiziga, mu gushyushya amazu, mu gutanga amashanyarazi no mu nganda. Amashyiga ya gazi n'ibindi bikoresho bitwika ibicanwa bishobora na byo kuyisohora mu nzu. Igira uruhare mu ikorwa rya ozone n'uduce duto cyane mu kirere.

Ozone yo hafi y'ubutaka (O₃) ikorwa iyo urumuri rw'izuba rutuma okiside za azote n'ibinyabutabire bikomoka kuri karubone bihinduka umwuka byoroshye bikorana. Urugero rwayo akenshi rurazamuka iyo hari izuba, kandi ihumana rishobora gutwarwa rikagera kure y'aho rikomoka. Ozone yo hafi y'ubutaka yangiza ubuzima; itandukanye n'urwego rwa ozone rudukingira ruri hejuru mu kirere.
