La présence du radical hydroxyle est fondamentale dans le phénomène d'effet de serre. Ce radical constitue un puits très important pour le monoxyde de carbone et le méthane. Il nettoie littéralement l'atmosphère de plusieurs gaz à effet radiatif. Sa disparition aurait pour conséquence des augmentations marquées de la concentration des gaz à effet de serre. 8, record 1, French, - hydroxyle

radical HO· : nom descriptif. Les points sont en exposant HO· lorsque le nom du radical se termine par «yle», par exemple «hydroxyle». Ce sont des points centrés entre parenthèses après les noms qui n'ont pas le suffixe «-yle». Par exemple : hydruroxygène(·) ou HO(·). 2, record 1, French, - hydroxyle

From the fuel itself, the engines also produce oxides of hydrogen, which include water, and which the chemists collectively dub HOx. Water itself does not destroy ozone, but the hydroxyl radical, HO, does, through a similar set of reactions to the ones involving NO. McDonald himself wasn't concerned about the effects of NOx on the stratosphere, but he began to be worried that HOx might have a serious effect on the ozone layer. 4, record 2, English, - hydridooxygen%26%23183%3B

Another sink for ozone involves fragments of water molecules. Water vapor occurs naturally in the stratosphere, and water molecules are also split apart by ultraviolet rays, giving a collection of hydrogen atoms (H), hydroxyl radicals (HO) and hydroperoxyl radicals (HOO). Collectively they can be symbolized by HOx. These remove ozone (or oxygen atoms needed to make ozone). 5, record 2, English, - hydridooxygen%26%23183%3B

Les scientifiques ont calculé que les oxydes d'azote pouvaient détruire jusqu'à 9 % de l'ozone de la stratosphère (de 15 à 50 km d'altitude), tandis que les oxydes d'hydrogène étaient responsables de la destruction de quelques 70 % de l'ozone de la mésosphère (entre 50 et 90 km). 5, record 2, French, - hydrurooxyg%C3%A8ne%26%23183%3B
