Study suggests that being too clean can make people sick

2D structure of antibacterial / antifungal age...Image via WikipediaA recent study by the University of Michigan School of Public Health suggests that people who are overexposed to endocrine-disrupting compounds (EDCs) may suffer more allergies and negative effects to their immune systems.  Study suggests that being too clean can make people sick.  This study indicates that young people who are overexposed to antibacterial soaps containing triclosan may suffer more allergies, and exposure to higher levels of Bisphenol A (BPA) among adults may negatively influence the immune system.  Triclosan is a chemical compound widely used in products such as antibacterial soaps, toothpaste, pens, diaper bags and medical devices.  BPA is found in many plastics and, for example, as a protective lining in food cans.  Both of these chemicals are in a class of environmental toxicants called endocrine-disrupting compounds (EDCs), which are believed to negatively impact human health by mimicking or affecting hormones.  "We found that people over age 18 with higher levels of BPA exposure had higher CMV antibody levels, which suggests their cell-mediated immune system may not be functioning properly," said Erin Rees Clayton, research investigator at the U-M School of Public Health and first author on the paper.  The study also found that people age 18 and under with higher levels of triclosan were more likely to report diagnosis of allergies and hay fever.  There is growing concern among the scientific community and consumer groups that these EDCs are dangerous to humans at lower levels than previously thought.

5 Easy Ways to Improve Indoor Air Quality - My Money (usnews.com)

Paint and Indoor Air QualityImage by kqedquest via FlickrThe garage as far as we are concerned is one of the most dangerous areas of the home.  Between the car, tool, and chemical storage it can have various items that by themselves would have significant impacts on indoor air quality.  Individually, cars can impact air quality with the carbon monoxide they produce that can infiltrate the home, tools, depending on what powers them, can also have the same effect as a car or can generate contaminants like sawdust, silica, asbestos or other hazardous vapors, and chemical storage by itself can generate volatile organic compounds (VOCs) and other hazardous vapors and mists.   The above article points out various ways you can improve your air quality and the ideas are excellent.

Floorings Affect on Indoor Air Quality

Mold growing on wood tacking under carpeting.
When Future Environment Designs performs an indoor air quality assessment we typically look at what's on the floor to see if that is hindering or contributing to the air quality problems.  Carpeting is a problem because the average person cannot clean it properly and if it gets wet you have to make sure you dry it completely to ensure mold (fungi) won't grow on it or in it.  We have seen mold grow even on the wood used for the tacking down the carpet as seen in the photo.  My preference is non-porous materials on the floor.  Researchers are now concerned about certain non-porous floors containing vinyl.  As the above linked article at Rodale.com "Caution: Floor May Be Toxic" discusses vinyl (PVC) and why it should be avoided.  The article says that researchers found that "PVC building materials, namely, vinyl flooring and coated wallpaper, were seven times more likely to contain hazardous additives when compared to nonplastic flooring options."  Vinyl flooring was also found to contain asbestos, cadmium, lead, and flame retardants.  "These substances are linked to asthma, fertility problems, learning disability, hormone-related diseases, and cancer."  It seems we will have to change our typical recommendation of vinyl floor tiles to linoleum, cork, bamboo and/or hardwood floors.  These floors are also approved for points under the Leadership Energy and Environmental Design (LEED) system.  The next time you are having problems with your flooring or considering remodeling look at linoleum, cork, bamboo and hardwood as better alternatives to vinyl floors or carpeting.
