Two of the gases are accumulating at a rate that is causing concern among researchers.

But the precise origin of these new, similar substances remains a mystery, say scientists.

"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."

"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," he added.

These substances aren't really new and they aren't really mysterious -- they just haven't been detected in the environment in significant conc'ns before, and it's not clear how they escaped. Dumping of production overruns or contaminated batches should be suspected.
