Vehicle exhaust emissions are maligned as the main source of air pollution that is very hazardous to the environment and the health of millions of people all around the world. However a recent study shows that simply breathing the air and dust inside a car is potentially more dangerous.
Many people find the smell of a new car pleasant; a leather and plastic aroma that many people find seductive, even addictive. However this “fragrance†is actually a potent mix of chemicals and toxins that can endanger the health of anyone who breathes it in. These chemicals are known as volatile organic compounds (VOCs) and include PBDE and phthalate.
A study conducted by the Ecology Center found that the chemicals that are used to make seat cushions, armrests, floor coverings, wire insulation and other interior auto components break down under exposure to high temperatures, for instance when parking under the sun, and are released into the air inside the car.
Windshield film and dust were collected by the Center from 11 model cars from the leading automakers from 2000-20005. They found that these residuals contain hazardous amounts of PBDE’s and Phthalates that have been linked to various damaging effects such as cancer, liver toxicity, birth defects, impaired learning and other serious health problems.
There are much safer alternatives that innovative auto manufacturers are encouraged to use instead of these harmful chemicals. Fortunately, leading auto manufacturers are implementing a phase out of these chemicals. Volvo leads the industry in terms of indoor air quality. Honda and Ford have reported that they have eliminated PBDE’s and phthalate-containing PVC from their respective vehicles.
All over the world, legislation have also been passed to eliminate PBDE’s and other VOCs in various products, including automotive equipment. The Japanese Auto Manufacturers Association has initiated the move to improve air quality in cars with several members indicating their effort to reduce the use of VOCs and other dangerous chemicals.
