Why “Zero VOC’s” can still shorten your life

“Zero VOC’s” has become a the tipping point between products judged “good” or “bad”. This is misleading. Volatile organic compounds (VOC’s) describes a molecular relationship, not a material. There are VOC’s that are harmful to the environment because they react photochemically and contribute to smog. Additionally there are VOC’s that have no evidence or history of being deleterious to human health.

The Environmental Protection Agency’s (EPA) mandate is about what happens outdoors. Indoor air pollution is not addressed by the EPA (or any other government agency). The following is a list the EPA excludes from being defined as a “harmful” VOC because (quoted directly from their intro to this list) “This includes any such organic compound other than the following, which have been determined to have negligible photochemical reactivity”… in other words, not contributing to smog.

So “Zero VOC, or VOC-free” can include the following:

  • methane

  • 1,2-dichloro-1,1,2-trifluoroethane (HCFC-123a)
  • 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxy-butane (C4F9OCH3 or HFE-7100)
  • 2-(difluoromethoxymethyl)-1,1,1,2,3,3,3-heptafluoropropane ((CF3)2CFCF2OCH3)
  • 1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane (C4F9OC2H5 or HFE-7200)

and perfluorocarbon compounds which fall into these classes:

  1. cyclic, branched, or linear, completely fluorinated alkanes,
  2. cyclic, branched, or linear, completely fluorinated ethers with no unsaturations,
  3. cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations, and
  4. sulfur containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine.

Indoor air pollution in depth

Indoor air pollution, in homes as well as commercial buildings, is being recognized as a serious health problem. Because most people in the United States spend an estimated 90 percent of their time indoors, the health risks of poor indoor air quality can significantly increase the risk of health problems. You may think indoor air pollution won’t affect you, but chances are it already has. Have you ever felt nauseated after painting or cleaning? Well, that’s a neurotoxin for you. The problem is, these toxins affect you all the time. You might not feel downright sick, but maybe you’ll feel run down and headachy as the day wears on. And it gets worse. Many of these toxins have a cumulative effect. You never get rid of them. They collect until you reach your threshold. Every year thousands of men, women and children will suffer illnesses from indoor air pollution. (more…)

Concerned about VOCs?

Since world war II, chemical use has grown by leaps and bounds. In 1945, annual production of synthetic chemical substances was 1 billion pounds. By 1987 it was 287 billion pounds, and growing every year. During that same period, doctors began noticing the phenomenon now recognized as multiple chemical sensitivity, a condition in which individuals become sensitized to chemicals by indoor air pollution and other exposures, and then suffer a variety of adverse reactions to low levels of chemicals from consumer and building products. In 1945 this phenomenon was unheard of. In 1987 it was estimated to affect up to 15% of the population. (more…)
