Mysterious gases
The four new gases have been identified as CFC-112, CFC112a, CFC-113a, HCFC-133a
CFC-113a has been listed as an “agrochemical intermediate for the manufacture of pyrethroids”, a type of insecticide once widely used in agriculture
CFC-113a and HCFC-133a are intermediaries in the production of widely used refrigerants
CFC-112 and 112a may have been used in the production of solvents used to clean electrical components
Other scientists acknowledged that while the current concentrations of these gases are small and they don’t present an immediate concern, work would have to be done to identify their origin.
“This paper highlights that ozone depletion is not yet yesterday’s story,” said Prof Piers Forster, from the University of Leeds.
“The concentrations found in this study are tiny. Nevertheless, this paper reminds us we need to be vigilant and continually monitor the atmosphere for even small amounts of these gases creeping up, either through accidental or unplanned emissions.
“Of the four species identified, CFC-113a seems the most worrying as there is a very small but growing emission source somewhere, maybe from agricultural insecticides. We should find it and take it out of production.”

More study funds/grants will be needed to ‘study’ this matter further. ;-}
You should save them some research money and let them know you have discovered the “new” gases are really old gases.
