Cfcs cause deterioration of the ozone layer the deterioration of the ozone layer , caused by cfcs, endangers the lives of humans' cfcs have a diminishing effect on the ozone layer furthermore, the deterioration of the ozone cause an increase of ultraviolet (uv) radiation which can have a negative effect on human skin and eyes as a writer for. They calculated that if cfc production continued to increase at the going rate of 10%/year until 1990, then remain steady, cfcs would cause a global 5 to 7 percent ozone loss by 1995 and 30-50%. Waterloo, ont (thursday, may 30, 2013) - chlorofluorocarbons (cfcs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the university of waterloo published in the international journal of modern physics b this week cfcs are already known to deplete ozone, but in-depth statistical analysis now shows that cfcs are also the key driver in. For instance, hcfcs (hydrochlorofluorocarbons) can also potentially deplete ozone gas in the stratosphere, but not nearly to the extent of cfcs [source: ucs] the efforts seem to be working reports show that by 2049, the ozone will recover to 1979 thickness, which is when scientists believe the hole began to form [source: reuters.
Chlorofluorocarbons (cfcs) have been found to cause the depletion of the ozone layer the ozone layer prevents ultraviolet radiations of the sun from coming on the earth this article describes the process of damaging effects of cfcs. In layman terms, it is the deterioration of the ozone layer as a result of several factors, but most importantly pollution the leading cause of pollution is the cfcs (chlorofluorocarbons. Causes of ozone layer depletion: the main cause of ozone layer depletion is the build-up of cfcs (chlorofluorocarbons) in the atmosphere when the cfcs reach the upper atmosphere, high uv radiation reacts with these and releases chlorine atoms.
Scientists calculated that if cfc production continued to increase at the going rate of 10 percent per year until 1990 and then remain steady, cfcs would cause a global ozone loss of 5–7 percent by 1995, and a 30–50 percent loss by 2050. Cfcs cause deterioration of the ozone layer the deterioration of the ozone layer , caused by cfcs, endangers the lives of humans' cfcs have a diminishing effect on the ozone layer furthermore, the deterioration of the ozone cause an increase of ultraviolet (uv) radiation which can have a negative effect on human skin and eyes. What is the ozone hole in the middle of the 20th century, a collective interest in the human effect on the environment had begun to emerge scientists were keenly observing how interference by society in the natural processes of earth worked out. Paradoxically, the ozone hole in 2011 was about as big as it was in 2006, even though cfcs should have declined in those years due to the phasing out of their use.
Cfcs affect the ozone layer by destroying ozone molecules cfcs, or chlorofluorocarbons, are normally stable molecules, but when uv rays strike them, they are broken down the chlorine atom released from a cfc wreaks havoc on ozone molecules. Ozone levels reached their lowest levels in the 1990s and there have been corresponding decreases in all ozone levels in populated areas since 2002 numerous experiments have shown that cfcs and other widely-used chemicals produce roughly 84% of the chlorine in the stratosphere. Man-made causes of depletion of ozone layer: the main cause for the depletion of ozone is determined as excessive release of chlorine and bromine from man-made compounds such as chlorofluorocarbons (cfcs. The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons (cfcs), hcfcs, halons), referred to as ozone-depleting substances (ods.
The cfc's go into the stratosphere and there they cause ozone depletion by breaking down the ozone molecules if the ozone layer keeps breaking down, then there will soon be a hole in the ozone layer which will take 50 years to heal. The ozone in the ozone layer is being broken down by chlorine atoms from chlorofluorocarbon (cfc) molecules and bromine atoms from halons cfcs and halons are produced by humans used in many applications such as refrigerants, anaesthetics, aerosols, fire-fighting equipment and the manufacture of materials such as stryrofoam. What are they chlorofluorocarbons (cfcs) are a group of odorless manufactured chemicals because they damage the earth’s ozone layer, cfcs have been banned since 1996 before cfcs were banned, they were used in aerosols, refrigerators, air conditioners, foam food packaging, and fire extinguishers.
A layer of ozone envelops the earth and keeps damaging ultraviolet, or uv, radiation from reaching living things on the planet's surface the ozone layer exists mainly in the stratosphere, a layer of the atmosphere that reaches from 10 to 50 kilometers (about 6 to 30 miles) above the earth's surface. The gaping hole in the ozone layer of the atmosphere over the antarctic was caused primarily by high concentrations of ozone-depleting chemicals called cfcs the vast hole in the ozone was discovered by scientists in the 1980s, who upon discovering the dramatic loss in ozone cover, set to work. Cfcs have a lifetime in the atmosphere of about 20 to 100 years, and consequently one free chlorine atom from a cfc molecule can do a lot of damage, destroying ozone molecules for a long time although emissions of cfcs around the developed world have largely ceased due to international control agreements, the damage to the stratospheric ozone.
Cfcs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity how ozone works how ozone is distributed in the atmosphere. What is ozone depletion ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere unlike pollution, which has many types and causes, ozone depletion has been pinned down to one major human activity. Scientists were able to identify a problem (the depletion of the ozone layer) and its cause (chlorofluorocarbon gases or cfcs) and within two years, politicians took swift action to reverse course to protect our planet and its inhabitants. Manufactured chemical compounds are the main cause of ozone layer depletion these are compounds such as chlorofluorocarbons (cfcs) and halons, among others in the past, these compounds were commonly used in refrigerators, air conditionners and fire-retardant chemicals.
