Lovelock had measured trichlorofluoromethane (CFC-11) in the atmosphere in amounts that suggested that practically all of the CFC-11 ever manufactured was still present in the atmosphere. Most refrigerants found in air conditioners, refrigerators, and freezers contain fluorocarbons, and many fluorocarbon compounds contain chlorine. Chlorofluorocarbon (CFC) refrigerants were commonly used in equipment manufactured before 1995.

After a series of fatal accidents in the 1920s when methyl chloride leaked out of refrigerators, a search for a less toxic replacement began as a collaborative effort of three American corporations- Frigidaire, General Motors, and Du Pont. Ozone-depleting substances (ODS) contain various combinations of the chemical elements chlorine, fluorine, bromine, carbon, and hydrogen and are often described by the general term halocarbons. These substances are effective ozone-depleters for two reasons.

Rafsan Chowdhury. Dec 31, 2014 @ 3:15 pm. 2019-05-23 CFCs : (1) Chlorofluorocarbons (CFCs) are a group of compounds which contain the elements chlorine, fluorine and carbon. (2) At room temperatures, they are usually colourless gases or liquids which evaporate easily.

gas analyses were carried out at the Bremen Mass. Spectrometric Facility according to Sültenfuss et al. (2009). CFC sampling and analysis were conducted. gases were introduced in the nineties to replace the ozone-depleting CFCs and of ozone-depleting substances, and these are used in a variety of spheres.
