1,1,1-Trichloro-2,2,2-trifluoroethane
Asymmetrical trichlorotrifluoroethane, also called 1,1,1-Trichloro-2,2,2-trifluoroethane or CFC-113a is a chlorofluorocarbon (CFC). It has the formula . Environmental effects 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 CFC's 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 Montreal Protocol is an international treaty A treaty is a formal, legally binding written agreement between actors in international law. It is usually made by and between sovereign states, but can include international organization ..., the abundance of CFC-113a in the atmosphere was still growing. Its source remained uncertain, but production of hydrofluorocarbons in East Asia was suspected by some. Between 2012 and 2017, concent ...
