You may have been hearing a lot of buzz about VOCs recently. That is a good thing. If you are not sure what they are, think about that new car smell, your favorite air freshener or even your dryer sheets. I know what you’re thinking here goes another blogger on a rant. Nope, it stops there. But if you are interested in more than just opinion, read on.
Volatile organic compounds (VOCs) are carbon-based chemicals emitted as gases from certain solids or liquids. There are a wide variety of chemicals that emit VOCs and contribute to air pollution, some of which may have short- or long-term health effects.
Air testing has shown that the concentrations of many VOCs are consistently higher indoors than outdoors. EPA's Office of Research and Development conducted a "Total Exposure Assessment Methodology (TEAM) Study" that found the levels of about a dozen common pollutants to be 2 to 5 times higher inside homes than outside, regardless of whether the homes were located in rural or highly industrial areas. Studies indicate that as people use products containing organic chemicals, they may be jeopardizing their home air quality and exposing themselves and others to very high pollutant levels.
Elevated concentrations of VOCs can persist in the air long after the activity is completed. This is due to a period of "off gassing" after a product containing VOCs has been applied. That familiar new car smell, the lingering aroma of new carpet or a freshly painted room is a prime example of off gassing. Fortunately, the green movement and consumer demand are driving manufacturers to offer "VOC Free" options that are just as good as those containing harmful chemicals. All you need to do is look for those choices to improve your air quality and have cleaner air indoors.
