Scientists have discovered that four man-made gases with the potential to damage the ozone layer have been escaping into the atmosphere. Even more alarming is that at the moment, where these are coming from remains a mystery.
"The identification of these four new gases is very worrying as they will contribute to the destruction of the ozone layer," Dr. Johannes Laube from the University of East Anglia, who is the lead author of the research paper published Sunday in the journal Nature, told BBC News.
"We don't know where the new gases are being emitted from and this should be investigated. Possible sources include feedstock chemicals for insecticide production and solvents for cleaning electronic components," he added. "What's more, the three CFCs are being destroyed very slowly in the atmosphere — so even if emissions were to stop immediately, they will still be around for many decades to come."
