The stratospheric ozone layer has undergone severe depletion as a result of anthropogenic ... Nitrous oxide behaves in a similar way to chlorofluorocarbons (CFCs): it is very stable in the lower ...

Later amendments to the Montreal Protocol completely phased out production of CFCs. Past studies have used statistical analyses of changes in the ozone hole’s size to argue that ozone depletion ...

Scientists have identified four new man-made gases that are contributing to the depletion ... over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted ...

"Recognition of the adverse impact of chlorofluoro-carbons (CFCs) on stratospheric ozone has prompted ... HFC-134a does not contain chlorine and so has no ozone-depletion potential associated with the ...

Atmospheric halocarbons, including hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and chlorofluorocarbons (CFCs), are a group of chemicals that have significant implications for ...

The study focuses on the recovery of equivalent effective stratospheric chlorine (EESC), a critical metric for estimating stratospheric ozone depletion ... and CFC-11, further contributed to ...

Their observations revealed that the annual ozone layer above the South Pole was relatively small compared to other years ...

Together, these patents strengthen PyroGenesis’ SPARC technology that specifically targets the destruction of end-of-life (EOL) refrigerants such as CFCs ... against ozone depletion and ...
