Why food in the refrigerator is not poisonous in the presence of chlorofluorocarbons
Answers
Answer:
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.
Chlorofluorocarbons, commonly referred to as CFCs, are non-combustible liquids that were, at one time, frequently used as refrigerants and aerosol propellants, as well as for cleaning products. Since scientists linked CFCs to the depletion of the ozone layer, they have been largely phased out, but old refrigerators and other devices that use CFCs might still be in service. Through inhalation, digestion or other physical contact, as well as from exposure to harmful levels of ultraviolet rays, CFCs can have a negative impact on human health.
