What are VOCs and how to reduce the health risks of VOCs?

Website design By BotEap.comUnfortunately, there is no international standard or body regarding the classification of VOCs. VOCs or volatile organic compounds are carbon-containing compounds that are easily vaporized or released. Volatile organic compounds occur naturally in nature and are often perceived as odours.

Volatile organic compounds are found in a wide range of everyday products: in paints, adhesives, fuels, solvents, coatings, permanent markers, nail polish removers, dry cleaning agents, raw materials, coolants, wood preservatives, aerosol sprays, disinfectants, repellents of moths, air fresheners, photocopiers and paint strippers. Basically, any household product with a strong “chemical” smell probably contains VOCs.

As I mentioned in my opening paragraph, there is no international standard for defining VOCs, so something labeled ‘low VOC’ could be high in other VOCs not recognized by the VOC guidelines the manufacturer uses.

They get sore throats, breathing problems, nausea and dizziness. Exposure to VOCs can cause asthma and allergies. Exposure to certain VOCs has been shown to cause cancer in animals and is widely suspected to do the same in people. Benzene, the VOC found in cigarette smoke, is definitely carcinogenic.

• Ventilate your house properly. The biggest problem is the buildup of VOCs per billion parts in indoor areas. Open your windows, try not to seal your house from outside air. Mixing indoor and outdoor air dilutes VOC concentrations.
• Read the manufacturer’s recommendations on storage. If you have an open can of paint, leave it in the garage, away from where people live.
• If you have old paints, varnishes, paint strippers, copier ink, nail polish remover that you don’t use, dispose of them responsibly.
• Do not buy products that contain VOCs in bulk. You may save a few pennies, but you are bringing “poisons” into your living spaces, which should be minimized.
• And finally, keep exposure to benzene, methylene chloride, and perchlorethylene to a minimum. These are some of the worst VOCs in terms of human health problems. Benzene is present in cigarette smoke, stored fuels, and automobile exhaust; methylene chloride is present in paint strippers, spray paints and adhesive removers and; Perchlorethylene is present in freshly dry-cleaned materials and fabrics.

Website design By BotEap.comAnother VOC to watch out for is formaldehyde which is often found in furniture adhesives and varnishes. Formaldehyde has been shown to cause allergies in children and respiratory problems in adults. Today there are some glues and adhesives, such as Healthy Bond Adhesive and Sealant, that do not contain formaldehyde. Fuse strand-woven bamboo flooring manufactured by Bamboo Mountain uses a formaldehyde-free adhesive in the manufacturing process of the strand-woven bamboo. Colombia Forest Products uses a soy-based adhesive to make its plywood that does not contain formaldehyde. They use PureBond technology that synthetically mimics the byssal threads that mussels use to adhere to rocks. Another great product is Eimann Fabrik VOC Free Engine Degreaser which cleans dirt, grime, grease, and oil from your engine without emitting any toxic VOCs.

Nails look good without polish; stop using spray products and; cut back on your dry cleaning. In short, all those things that hit your house with a chemical smell are just bad for you and very bad for your children. Be especially careful with cheap furniture and plywood products.
