What are VOCs?
Volatile Organic Compounds, or VOCs, are chemicals that are emitted as gases from solids or liquids and easily evaporated into the air at room temperature. Concentrations of these chemicals can be up to 100 times higher indoors than outdoors. Thousands of products, many that we use every day, or are exposed to every day, emit VOCs into the air while they are being used, and, to some degree, even when they are stored. These products include: |
Paints & varnishes
Moth balls
Solvents
Building materials
Pesticides
Gasoline
Fuel oil
Cooking oils, etc.
Cleaning supplies
Carpeting
Wallpaper
Vinyl flooring |
Copiers & printers
Upholstery & fabrics
Glues & adhesives
Permanent markers
Craft materials
Cosmetics
Hair care products
Air fresheners
Disinfectants
Furniture (pressed wood)
Vehicle exhaust
Tobacco smoke |

While all VOCs have the potential to be harmful, there are a few common VOCs that can be particularly dangerous, and are emitted from a number of products in our homes. These common VOCs are formaldehyde, benzene, and phenol, and are classified as Hazardous Air Pollutants (HAPs) by the U.S. Environmental Protection Agency (EPA). For a complete list of all 188 HAPs, click here to visit the EPA website.
