Over 200 of the most popular 2006- and 2007-model vehicles in the U.S. were tested for chemicals that off-gas from indoor auto parts such as the steering wheel, dashboard, armrests and seats. These chemicals become part of the air we breathe contributing 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 is a major source of potential indoor air pollution.
