Three new ozone-depleting gases discovered in atmosphere
http://www.theguardian.com/environment/2014/jun/04/three-new-ozone-depleting-gases-discovered-in-atmosphereMore ozone-depleting gases have been identified in the atmosphere by scientists.
Researchers at the University of East Anglia (UEA) have found two new types of chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC).
The latest discovery comes after the UEA researchers identified four new man-made gases which contribute to destruction of the ozone layer in March, bringing the total number of newly discovered CFCs and HCFCs to seven.
Research published in the journal Atmosphere shows the scientists discovered the latest gases by comparing today's air samples with air collected between 1978 and 2012 in unpolluted Tasmania and samples taken during aircraft flights.
