HFCs [Hydrofluorocarbons] are produced synthetically and are used primarily as refrigerants. They became widely used for this purpose beginning in the late 1980s, with the introduction of the Montreal Protocol, which phased out the use of chemicals such as halons and chlorofluorocarbons(CFCs) that contribute to the depletion of Earth's ozone layer. However, while HFCs have an ozone depletion potential of zero, they are potent greenhouse gases, and thus their manufacture and use became increasingly regulated in the 21st century. 8, record 1, English, - hydridofluoridocarbon

La disminución de la capa de ozono es causada entre otros factores, por las actividades humanas a través de las emisiones a la atmosfera de sustancias que contienen cloro y bromo, capaces de destruir las moléculas de ozono. La mayor parte de estos gases se acumulan primeramente en la troposfera, estos no reaccionan, ni se disuelven con facilidad en la lluvia o la nieve, luego son desplazados y ascienden a la estratosfera donde se convierten en gases reactivos que participan en las reacciones que destruyen las moléculas de ozono. 2, record 2, Spanish, - agotamiento%20de%20la%20capa%20de%20ozono

[...] Dado que se trata de un nombre descriptivo de una región de la atmósfera donde aumenta la concentración de ozono, no hay razón para escribirlo con mayúscula, como tampoco se hace con las denominaciones de otras capas como la ionosfera o la estratosfera. [...] Asimismo, ozono se escribe con minúscula inicial por tratarse de una sustancia química [...] 4, record 2, Spanish, - agotamiento%20de%20la%20capa%20de%20ozono
