Scientists at the University of East Anglia have found two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) in the atmosphere.
The research, published today in the journal Atmosphere, comes after another four man-made gases were discovered by the same team in March.
Scientists made the discovery by comparing today’s air samples with air collected between 1978 and 2012 in unpolluted Tasmania, and samples taken during aircraft flights.
Measurements show that all but one of the new gases have been released into the atmosphere in recent years.
