年长的读者们会记得有些车辆注入的“元老级气态制冷剂”为R 12，一种氯氟碳(英文简称CFC)的混合物。
Older readers will remember vehicles fitted with the "old gas" called R12, a compound of Chlorine, Fluorine and Carbon (CFC).
科学家们认为人类造成臭氧层破坏的主要原因是一些化学物质，像氯氟碳，当它们到达平流层后会分解成氯和溴，然后和臭氧发生化学反应从而破坏臭氧层。
The problem with the ozone layer is that when certain chemicals, like chlorofluorocarbons, reach the stratosphere, they break down into chlorine and bromine, which react with the ozone and destroy it.
