What is VOC?

Have you ever walked into a department store and noticed that your nose begins to run and your eyes are watering after a few minutes?

Does repainting your kid’s bedroom give you a headache that lasts for hours? Do you feel slightly nauseated after new cabinetry or carpeting has been installed in your home? If so, you might have VOC chemical sensitivity. Researchers are uncovering more evidence of what items can emit these harmful chemicals and who, exactly, is most susceptible to their negative effects.

What is VOC?

VOC stands for Volatile Organic Compounds, which the EPA defines VOCs as gases emitted from certain solids or liquids, like paints, cleaning supplies, pesticides, building materials, furnishings, adhesives, permanent markers and more. Categorically, a VOC can encompass a medley of chemicals, and some of those have varying degrees of both short- and long-term adverse health effects. Due to an indoor environment’s natural lack of natural ventilation, levels of many VOCs are usually higher in buildings and home (up to 10 time higher) than outdoor environments.
Outside, a VOC can dissipate rather quickly; indoors, it disperses much slower, meaning anyone subjected to that indoor space is inhaling concentrated chemicals. Modern homes are being built to be more efficient, and are often designed to improve the efficacy of heating and cooling systems. This unintended negative side effect of this is that VOCs then have a harder time escaping through window cracks or poorly-insulated attics. The VOCs will then stay trapped longer in a home or office building, which increases the likelihood of human exposure.

Bob Vila — a name synonymous with home improvement and repair — notes that a phenomenon known as “off-gassing” is particularly problematic when it comes to VOCs. Off gassing (sometimes called outgassing) is the release of chemicals from various substances under normal conditions of temperature and pressure. Vila explains that as VOCs break down, they release gas into the air — and these gases can cause headaches, nausea, watery eyes, sore throats and more. A VOC may or may have detectable odors — so simply being able to smell the chemical is not the best indicator of potential health risks.

What produces VOCs?

Buildings.com, a community of facility managers and building owners responsible for the operation of commercial and public buildings, notes that “finishes and paints have numerous chemicals that are toxic, many of which are simply for keeping it liquid while it’s in the can….Furniture is a [another] common culprit because so many materials, from coatings and glues to particle board and upholstery, can contain VOCs.”

How to minimize off-gassing and VOC exposure?

One of the main ways to reduce the effects of off-gassing and VOC exposure, according to home expert Vila, is to “…[ventilate] a newly furnished room for at least a week after installation and always [buy] no- or low-VOC products when possible.”

If fresh air won’t aggravate your allergy or asthma symptoms, and the weather is permitting, opening doors and windows can allow an air exchange to occur, which can allow built-up fumes, odors and chemicals to escape. But with this method, just as harmful contaminants can exit your home, other irritants can enter at the same time. Pollen, wood smoke, mold spores, and other pollutants can waft in through open doors and windows, too.

For many people, a smarter option is to equip their home or office with the right air purifier. With technology advancing at such a fast rate, new options for air purification are rapidly entering the marketplace and into the hands of consumers with specific respiratory needs.
