Many of these volatile organic compounds (VOCs) are toxic or carcinogenic, but it is not certain that they would be at the concentrations in a car. BUT, they are also repiratory irritants. I have asthma, and it is a seriouis concern if I have to get a new car in the winter; this stuff will cause asthma attacks in people sensitive to these compounds. It is really good news for me that the new Civic and some other cars will be built with low VOCs.
