Is chlorofluorocarbons an air pollutant?
Is chlorofluorocarbons an air pollutant?
It can slow our reflexes and make us confused and sleepy. Carbon dioxide (CO2)is the principle greenhouse gas emitted as a result of human activities such as the burning of coal, oil, and natural gases. Chloroflorocarbons (CFC) are gases that are released mainly from air-conditioning systems and refrigeration.
Is chlorofluorocarbon a VOC?
The VOC’s that may cause stratospheric ozone depletion are mostly a chlorine-containing group of compounds known as Chloroflourocarbons or CFC’s. These compounds are particularly effective at destroying the ozone even when present in small quanitites.
Why is Chlorofluorocarbons a pollutant?
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.
What is the difference between chlorofluorocarbons and hydrofluorocarbons?
The key difference between CFC and HCFC is that the CFC contains only carbon, fluorine and chlorine atoms whereas HCFC contains hydrogen, carbon, fluorine and chlorine atoms. More importantly, CFC causes serious ozone depletion but HCFC, comparatively, has a much lesser impact on the ozone layer.
Why it is necessary to limit the use of chlorofluorocarbon?
Why are chlorofluorocarbons and Bromofluorocarbons called greenhouse gases?
Chlorofluorocarbons and bromofluorocarbons react with ozone layer and and makes compound which deplete the ozone layer as we know that ozone layer protect earth from harmful uv radiation and maintain temperature balance so it’s depletion cause green house effect . thus CFC are major green house agents.
Why are hydrofluorocarbons better than chlorofluorocarbons?
Because they contain hydrogen, HCFCs break down more easily in the atmosphere than do CFCs. Therefore, HCFCs have less ozone depletion potential, in addition to less global-warming potential. HFCs do not contain chlorine and do not contribute to destruction of stratospheric ozone.
How do greenhouse gases differ?
Different GHGs can have different effects on the Earth’s warming. Two key ways in which these gases differ from each other are their ability to absorb energy (their “radiative efficiency”), and how long they stay in the atmosphere (also known as their “lifetime”).
What is chlorofluorocarbon (CFC)?
Definition of chlorofluorocarbon : any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC
How do chlorofluorocarbons affect the environment?
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. Hydrofluorocarbons (HFCs) also act to warm the planet.
What are the harmful effects of CFCs on the environment?
CFC are a concern for us not for air pollution much but for them creating ozone holes in the atmosphere. Ozone (O3) in natural condition forms layer around earth . These ozone layers acts as a filter while sunrays reach earth , they block a lot of the uv rays which is carcinogenic in nature.
What is CFC gas made of?
It contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane. Commonly known by the name freon, the manufacture of CFCs. In the past 50 years, cfc emission has increased considerably. It is a colorless, odorless and chemically non-reactive gas.
