Almost everyone loves the “new car smell” when a brand new vehicle is purchased. However, it may not be so appealing once it is known that the smell may come from toxic chemicals used in the construction of the automobile. The Ecology Center in Ann Arbor, Michigan recently completed a study in which the composition of more than 200 late model SUVs, cars and trucks were analyzed for chemicals that emit gasses from parts used within the interior of the vehicle. The Ecology Center was most concerned with chlorine from plasticizers such as PVC, bromine coming from fire-retardant components and contamination from heavy metals such as lead.
Other institutions have also completed studies and some have shown the inside air pollution in cars is greater than air pollution inside houses and other buildings. These toxic emissions are a real threat to individuals’ physical health. Benzene and formaldehyde, for instance, have been shown to cause skin diseases and breathing problems. The chemicals also worsen allergies such as asthma, a potentially life-threatening condition. Children are particularly vulnerable to this atmosphere because their systems are not fully developed.
Positive Changes
In addition, asbestos was heavily used in automobile construction because of its strength and heat resistant properties. The parts that usually contained asbestos were brakes, gaskets,clutches, hood liners and heat-seal material, among others. Exposure to asbestos dust causes various health problems and diseases, including the deadly mesothelioma cancer. Automotive workers are particularly susceptible to this danger. Asbestos is no longer used in automotive construction.
Also on the plus side, the trend in greener living is beginning to influence the vehicle industry. Many car manufacturers are starting to produce automotive interiors that are less toxic or even toxic-free in some cases. Vegetable tanning is substituted for chromium, for instance, and use of metals and solvents are reduced. Water-based paint and recycled materials further help to eliminate toxic fumes. Soy based foam for seat cushions as well as recycled fabric are more environmentally friendly.
Consumers Can Help
Consumers can help this trend along by requesting increased responsibility from manufacturers to produce more toxic-free vehicle interiors. With more environmental research and adaptations in production, vehicles can be produced that are virtually free of toxic materials and substances that emit dangerous chemical fumes. Green materials already exist that can be used in automobile construction without endangering human health.
For those who have recently purchased a new vehicle, there are steps to be taken that can reduce exposure to the toxicity that may be present in the interior. Open windows as much as possible to allow fresh air into the vehicle. Do not run the air-conditioner more than absolutely necessary for about the fist six months. Check labels to avoid adding items to the car that contain toxic materials such as car seat covers and decorations.
