Comme la nomenclature industrielle Fréon ne distingue pas un dérivé chloré d'un dérivé bromé, on reconnaît le chlorotrifluorométhane (CC1F3) et le bromotrifluorométhane (CBrF3) en nommant le premier CFC 13 et le second CFC 13B1. Le B1 signale la présence d'un atome de brome; de la même façon l'appellation d'un autre hydrocarbure bromé, le CFC 114B2, signale la présence de deux atomes de brome. Il ne faut pas confondre la lettre majuscule B, indicatif du brome, avec la lettre minuscule b qui sert d'indicatif d'isomérie (le CFC 142b, pour le monochlorodifluoroéthane par exemple). 5, record 3, French, - bromotrifluorom%C3%A9thane

The ozone layer is the principal shield preventing harmful short-wave ultraviolet radiation from reaching the surface of the earth. Suggestions that man’s activities may be leading to a moderate reduction of the stratospheric ozone layer is of justifiable concern. Several threats such as exhaust emissions from high altitude aircraft and halomethanes diffusing up from the troposphere appear to have a sound theoretical support to serve as a basis of concern. 3, record 4, English, - halogenated%20methane
