Ringkasan

Deskripsi
English: Ozone-depleting gas trends and equivalent chlorine effect. Combined chlorine and bromine in the lower atmosphere or troposphere from the most abundant chlorinated and brominated chemicals controlled by the Montreal Protocol. These changes are reflected in the upper atmosphere stratosphere (10-25 km), where most ozone loss occurs, with a delay (due to air transport) of 3-5 years. Bromine is included as an ozone-depleting chemical because although it is not as abundant as chlorine, it is 45 to 60 times more effective per atom in destroying stratospheric ozone. Earlier measurements showed that the peak of equivalent chlorine (chlorine + 45 (or 60) times bromine) occurred at the surface between mid-1992 and mid-1994.[1] The observed decrease is driven by a large and rapid decline in methyl chloroform and methyl bromide, gases that are regulated internationally by the Montreal Protocol. The initial decline in methyl bromide was larger than that expected from projections given in the WMO/UNEP 2002 Scientific Assessment to Ozone Depletion.[2][3]
Français : Tendances pour les gaz appauvrissant la couche d'ozone (et effet en équivalent-chlore). Chlore et brome sont les halogènes destructeurs d'ozone les plus abondants, ils sont contrôlés par le Protocole de Montréal qui a permis leur réduction globale dans la haute atmosphère stratosphère (10-25 km), où la plupart de l'ozone se crée. Les effets apparaissent avec un retard de 3 à 5 ans (dû au transport aérien des CFC). Le brome est bien moins abondant que le chlore, mais il est 45 à 60 fois plus efficace par atome pour détruire l'ozone stratosphérique. Des mesures antérieures ont montré que le pic en «équivalent-chlore» (chlore + 45 (ou 60) fois brome) s'est produit à la surface entre mi-1992 et mi-1994 [1].
La diminution observée est due à une baisse importante et rapide du chloroforme de méthyle et du bromure de méthyle, pesticide et biocide gazeux réglementés mondialement par le Protocole de Montréal|Protocole de Montréal. La baisse initiale du bromure de méthyle a été plus importante qu'attendue par les projections de l’évaluation scientifique OMM / PNUE de 2002 sur l’appauvrissement de la couche d’ozone. [2] [3]
