Commuters are inhaling unacceptably high levels of carcinogens
Twenty minutes or longer in the car also raises risk of birth defects
A new study finds that California's commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.
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 you cross that threshold, the risk for disease increases.
Governmental agencies tend to regulate that threshold in workplaces. However, private spaces such as the interior of our 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 of exposure and are Prop. 65-listed chemicals.
New UC Riverside 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.
"These chemicals are very volatile, moving easily from plastics and textiles to the air that you breathe," said David Volz, UCR professor of environmental toxicology.
