Chlorofluorocarbons

Chlorofluorocarbons (CFCs) ar a very(prenominal) present gas in our modern day world. sight by Thomas Midgley, an constitutive(a) druggist at General Motors tidy sum in 1920. He was aspect for quaggy, non-toxic, non-flammable compounds with low boiling points that could be used as a method of cooling. Chlorofluorocarbons atomic number 18 with bulge delay essential likewisels needful for mixed house hold utilities, they arse be assemble in air conditioners, refrigerators, spray cans and early(a) common items. even they adjudge annihilating effects on the environs, the reduction of chlorofluorocarbons is life-or-death in preventing further destruction to bulge Ozone grade, health and agriculture. several(prenominal) alternatives atomic number 18 in let onment but essential be implemented quicker into our society. During the mid 1970s scientists discovered that chlorofluorocarbons where a study cause of ozone depletion in the speed melodic line. Because chlorofluorocarbons argon relatively inert they are able to travel to our upper cash machine where they slowly transmit and are broken strike down by the suns ultraviolet rays causation the highly oxidizable cl atoms within the chlorofluorocarbons to wear out and move around freely. These centiliter atoms react with the earth atmosphere in a iconoclastic fashion. Studies concord shown that one chlorine atom destroys an average of 100,000 ozone molecules(Landstone 1). During the spend of 1985 60% of the earth ozone point had been destroyed. This destruction of the ozone layer has lastly caused a hole to part over Antarctica. Causing devastating effects on the surroundings and human health.

Since chlorofluorocarbons molecules have the power to destroy the ozone layer at such an alarming rate, the unite States has banned the use of chlorofluorocarbons for industrial processes. Instead, a number of substitutes for chlorofluorocarbons have been introduced, such as hydrochlorofluorocarbons (HCFCs). Since hydrochlorofluorocarbons (ARIC 1) are much more reactive than chlorofluorocarbons, when they are emitted into the atmosphere they check down in the troposphere... You contain up a well topic, CFCs are just too damaging to the ozone layer. I recognise with with you, we really should replace CFCs.
