Method to trace persistent CFCs
Description: Persistent sources of CFCs are thought to be slowing the recovery of the ozone layer. The use of the refrigerants and aerosol propellants was restricted by a global treaty in 1987, but they have stayed in the air longer than many expected. A UK-German team has now shown how it is possible to chemically "fingerprint" CFCs to potentially trace their origin. [Source: BBC News]
