Trichlorotrifluoroethane, also called 1,1,1-Trichloro-2,2,2-trifluoroethane or CFC-113a is a chlorofluorocarbon (CFC). It has the formula Cl3C-CF3.

Environmental effects

Ozone depletion

It is one of four man-made chemicals newly discovered in the atmosphere by a team at the University of East Anglia. But CFC-113a is the only known CFC whose abundance in the atmosphere is still growing. CFC-113a seems to have been accumulating unabated since 1960. Its source remains a mystery, but illegal manufacturing in China is suspected by some. Between 2010 and 2012, emissions of the gas jumped by 45 percent.[3][4]
