Summary of the Article
1. Volatile organic compounds (VOCs) are organic compounds containing one or more carbon atoms that evaporate readily into the atmosphere. They do not include photo-chemically non-reactive compounds such as methane, ethane, and the chlorofluorocarbons (CFCs).
2. Common examples of VOCs that may be present in our daily lives are benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene.
3. Ozone is a regional pollutant that is formed in the atmosphere over time from emissions of VOCs and Nitrogen Oxides (NOx). VOCs are compounds that evaporate easily into the air.
4. Volatile organic compound (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions.
5. Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity.
6. CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms. Individual CFC molecules are labeled with a unique numbering system. For example, the CFC number of 11 indicates the number of atoms of carbon, hydrogen, fluorine, and chlorine (e.g. CCl3F as CFC-11).
7. Formaldehyde is one of the most common VOCs out there, largely because it’s present in everyday products such as molded plastics and lacquers. Avoid heating plastics and limit plastic use in general to keep concentrations of formaldehyde low.
8. Sources of VOCs include paints, paint strippers and other solvents, wood preservatives, aerosol sprays, cleansers and disinfectants, moth repellents and air fresheners, stored fuels and automotive products, hobby supplies, and dry-cleaned clothing.

What are considered VOCs
Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity2.
What are CFCs classified
CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms. Individual CFC molecules are labeled with a unique numbering system. For example, the CFC number of 11 indicates the number of atoms of carbon, hydrogen, fluorine, and chlorine (e.g. CCl3F as CFC-11).
What is the most common VOC
Formaldehyde. This is far and away one of the most common VOCs out there, largely because it's present in everyday products such as molded plastics and lacquers. Avoid heating plastics, and limit plastic use in general so as to keep concentrations of formaldehyde low.
What are 5 common sources of VOCs
Sources of VOCspaints, paint strippers and other solvents.wood preservatives.aerosol sprays.cleansers and disinfectants.moth repellents and air fresheners.stored fuels and automotive products.hobby supplies.dry-cleaned clothing.
What are VOCs classified
VOCs are a class of chemicals that are volatile (evaporate easily) and are organic compounds (contain carbon atoms). Some common VOCs include acetone and automotive gasoline. Substances Listing.
What qualifies as a VOC
" Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions.
Are CFCs air pollutants
Chlorofluorocarbons are air polluting agents.
What is the category of CFC pollutant or contaminant
Hint: CFCs stand for chlorofluorocarbons. These are nonflammable chemicals which are used as refrigerants, in manufacturing of aerosols, etc. These are considered pollutants as they destroy the protective ozone layer and are responsible for increasing temperature conditions leading to global warming.
What is considered a VOC

How do you know if a chemical is a VOC
A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa.
What are VOC compliant products
VOC-compliant is an abbreviation of the term "volatile organic compound-compliant." This refers to a system, substance or application that adheres to governmental regulations regarding volatile organic compounds.
What type of pollutant is CFC
Chlorofluorocarbons (CFCs) are anthropogenic compounds that have been released into the atmosphere since the 1930s in various applications such as in air-conditioning, refrigeration, blowing agents in foams, insulations and packing materials, propellants in aerosol cans, and as solvents.
What type of pollution is CFC
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. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
What is the classification of CFC
Classification of CFC Gases
Chlorofluorocarbons are classified as halocarbons. Halocarbons are a class of compounds containing atoms of carbon and halogen atoms.
What are VOC products
VOCs are often components of petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning agents. VOCs are common ground-water contaminants. Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids.
What is acceptable VOC
0 to 400 ppb: This is the acceptable level of VOC indoors. You should not expect short-term effects such as irritation or discomfort. 400 to 2,200 ppb: Short-term exposure can result in noticeable effects such as headaches, nausea, dizziness, and irritation of the respiratory tract and eyes.
Is CFC toxic or non toxic
Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.
What are CFCs commonly known as
CFCs are also called Freons, a trademark of the E.I. du Pont de Nemours & Company in Wilmington, Del. CFCs were originally developed as refrigerants during the 1930s.
Is CFC toxic or not
WARNING! Working with chlorofluorocarbon 113 (CFC-113) or other chlorofluorocarbons in confined spaces may cause death by cardiac arrhythmia or asphyxiation.
How do you determine if a chemical is a VOC
A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa.
What is the OSHA standard on VOC
Occupational Safety and Health Administration (OSHA) regulates formaldehyde, a specific VOC, as a carcinogen. OSHA has adopted a Permissible Exposure Level (PEL) of . 75 ppm, and an action level of 0.5 ppm. US Department of Housing and Urban Development (HUD) has established a level of 0.4 ppm for mobile homes.
