Unacceptably high levels of carcinogens inhaled by commuters

Average commuters in California are potentially inhaling chemicals at levels that increase risk of birth defects, cancer- New findings. As with most chemicals, the poison is in the amount. Under a certain threshold of exposure, even known carcinogens are not likely to cause cancer. Once the person crosses that threshold, the risk for disease increases. Governmental agencies tend to regulate that threshold in workplaces However, private spaces such as the interior of cars and living rooms are less studied and less regulated Benzene and formaldehyde - both used in automobile manufacturing are known to cause cancer at or above certain levels. New research shows that the average commuter in California is exceeding the threshold for exposure, breathing in unsustainably high levels of both chemicals. Both benzene and formaldehyde are carcinogens, and benzene carries the additional risk of reproductive and developmental toxicity.
