“A study led by the National Oceanic and Atmospheric Administration (NOAA) found that although 95 percent of raw oil winds up being burned in vehicle engines, the remaining five percent that is refined into chemicals for household products could be doing about the same amount of damage to our lungs and crops.
The research looked specifically at air pollution in the Los Angeles area, long thought to be choked with smog created by the region’s abundant traffic. It finds that in the case of tiny, lung-damaging particles, the emissions that create them in the atmosphere come from chemical products over vehicles by a factor of two to one.”
