Ozone depletion A team of researchers at the University of East Anglia analysed unpolluted air samples from Tasmania dating from the period 1978 to 2012. They concluded that the CFCsAugust 2024 they studied had started entering the atmosphere from anthropogenic sources in the 1960s and that while the abundance of certain CFCs had decreased, owing to the Montreal Protocol, the abundance of CFC-113a in the atmosphere was still growing.Laube Johannes C.
