1. Volatile Organic Compounds  are compounds that have a high vapor pressure and low water solubility. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants.
2. Health effects may include:

  • Eye, nose and throat irritation
  • Headaches, loss of coordination and nausea
  • Damage to liver, kidney and central nervous system
  • Some organics can cause cancer in animals, some are suspected or known to cause cancer in humans.

Some have been linked to causing cancer and when combined with air pollution, they can be particularly dangerous to breathe. The health effects of VOCs exposure can be broken down into short term and long term symptoms:

    Short term:

    • Eye and respiratory tract irritation
    • Headaches
    • Dizziness
    • Visual disorders
    • Nausea
    Long term:

    • Damage to the liver, kidneys, and central nervous system
    • Cancer
    • Extensive irritation to the eyes, nose, and throat
    • Chronic fatigue
    • Loss of coordination
    • Memory loss
    How VOCs affect a person’s health varies greatly upon exposure time, levels, and if the individual is already at risk for other health issues. For asthmatics or people who already have sensitivities to certain chemicals, symptoms may be more acute. Always contact your doctor if you have questions regarding a certain reaction to a suspected chemical.

Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. VOCs typically are industrial solvents, such as trichloroethylene; fuel oxygenates, such as methyl tert-butyl ether (MTBE); or by-products produced by chlorination in water treatment, such as chloroform. 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. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.  VOCs are emitted by a wide array of products numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions.

    Health effects may include:

    • Headache
    • Nausea
    • Confusion
    • Cough
    • Wheezing or restricted breathing
    • Dizziness
    • Nose and throat irritation

    • If not possible to remove, reduce exposure by using a sealant on all exposed surfaces of paneling and other furnishings.
  • Use integrated pest management techniques to reduce the need for pesticides.
  • Use household products according to manufacturer's directions.
  • Make sure you provide plenty of fresh air when using these products.
  • Throw away unused or little-used containers safely; buy in quantities that you will use soon.
  • Keep out of reach of children and pets.
  • Never mix household care products unless directed on the label.

    How does it impact public health? Under the right conditions, many VOCs form ground-level ozone by “reacting” with sources of oxygen molecules such as nitrogen oxides (NOx), and carbon monoxide (CO) in the atmosphere in the presence of sunlight. The chemical reactions produce sub-micron sized particles and harmful by-products that may be associated with adverse health effects in some sensitive populations.
