You know that “new car smell” that every new car  comes with that let’s you know it’s a new car?  Well, it turns out that that smell is a mixture of toxic chemicals that YOU AND YOUR DOG should be concerned about.  This press release from the Ecology Center and healthystuff.org will fill you in on this environmental pollution:

Honda Rated as Top Manufacturer; PVC Reduction Efforts Hailed

(Ann Arbor, MI) – Today the Ecology Center released its fourth consumer guide to toxic chemicals in cars at HealthyStuff.org, finding the Honda Civic at the top of this year’s list, and the Mitsubishi Outlander Sport at the bottom. Over 200 of the most popular 2011- and 2012-model vehicles were tested for chemicals that off-gas from parts such as the steering wheel, dashboard, armrests and seats. These chemicals contribute to “new car smell” and a variety of acute and long-term health concerns. Since the average American spends more than 1.5 hours in a car every day, toxic chemical exposure inside vehicles can be a major source of indoor air pollution.

“Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas in small, confined spaces,” said Jeff Gearhart, Research Director at the Ecology Center. “Since these chemicals are not regulated, consumers have no way of knowing the dangers they face. Our testing is intended to expose those dangers and encourage manufacturers to use safer alternatives.”

Chemicals of primary concern include: bromine (associated with brominated flame retardants); chlorine (indicating the presence of polyvinyl chloride, or PVC and plasticizers); lead; and heavy metals. Such chemicals have been linked to a wide range of health problems such as allergies, birth defects, impaired learning, liver toxicity, and cancer. Automobiles are particularly harsh environments for plastics, as extreme air temperatures of 192 F and dash temperatures up to 248 F can increase the concentration of Volatile Organic Compounds (VOC’s) and break other chemicals down into more toxic substances.

“Automobiles function as chemical reactors, creating one of the most hazardous environments we spend time in,” added Gearhart.

The good news is overall vehicle ratings are improving. The best vehicles today have eliminated hazardous flame retardants and PVC. Today, 17% of new vehicles have PVC-free interiors and 60% are produced without BFRs.

Top ranking cars in this year’s release are: 1) Honda Civic 2) Toyota Prius and 3) Honda CR-Z. Worst ranking: 1) Mitsubishi Outlander Sport 2) Chrysler 200 SC and 3) Kia Soul. The Civic achieved its ranking by being free of bromine-based flame retardants in all interior components; utilizing PVC-free interior fabrics and interior trim; and having low levels of heavy metals and other metal allergens. The Mitsubishi Outlander contained bromine and antimony-based flame retardants in the seating and center console; chromium treated leather on several components; and over 400 ppm lead in seating materials.
