In 1950, the atmospheric concentration of CFCs (chlorofluorocarbons) was around 50 parts per trillion (ppt), as they were just beginning to be used in commercial products. Their levels increased significantly over the following decades due to their use in aerosol sprays, refrigerators, and air conditioners.
