Are Cfcs Bad Chlorofluorocarbons CFCs and hydrochlorofluorocarbons HCFCs are fully or partly halogenated hydrocarbons that contain carbon C hydrogen H chlorine Cl and fluorine F produced as volatile derivatives of methane ethane and propane The most common example is dichlorodifluoromethane R 12 R 12 is also commonly called Freon and was used as a refrigerant Many CFCs have bee
At the University of California Irvine F Sherwood Rowland and Mario J Molina discovered that chlorofluorocarbons CFCs could deplete Earth s atmospheric ozone layer which blocks the sun s damaging ultraviolet rays Through inhalation digestion or other physical contact as well as from exposure to harmful levels of ultraviolet rays CFCs can have a negative

These days we know that carbon dioxide is bad but CFCs are even more potent the facts made it clear that something needed to be done Are CFCs banned After the mounting evidence throughout the 1970s Although pockets of production continue to exist general prohibition is likely to eliminate CFCs shortly Thanks to their perceived reduced potential to exercise ozone damage CFCs were quickly replaced by HCFCs HCFCs are less
CFCs contribute to the loss of the protective ozone layer which blocks ultraviolet rays from the sun This exposes more people to UV radiation which can cause skin cancer Why Are CFCs Still a Problem Even though the Montreal Protocol in 1987 banned the production of most CFCs their long atmospheric lifespan means they re still present today Think of it like this a CFC molecule released in the

CFCs have a life in the atmosphere of anywhere from 20 to 100 years meaning the harmful effects can be felt for decades The harmful element that works regarding global warming is carbon Carbon helps keep heat in the A Effects of CFCs on Humans Its exposure may adversely affect human health through inhalation ingestion or direct touch raising the risk of dangerous UV radiation exposure Breathing these compounds can cause
The advent of chlorofluorocarbons or CFCs threatened the ozone layer and the survival of Earth dwellers Manufacturers thought the chemicals were the panacea to their manufacturing headaches because CFCs emitted CFCs were banned in the 1980s under an international agreement called the Montreal Protocol not because of climate change but because they also have a significant
