The Health Problem
Whether it’s spikes in low birth weights in Los Angeles or off-the chart asthma cases in Minneapolis, the patterns are consistent, and exposure to urban air and high levels of traffic pollution can have profound health effects. This is due to the fact that aromatics come out of our vehicles as ultra-fine particulates that bypass the lungs and directly enter the bloodstream. Ultra-fine particulates are not found in nature, they are only man-made. So, our body’s natural defenses can’t filter the threat of something that’s smaller than the width of a human hair.
A study published in the American Journal of Epidemiology says benzene in traffic emissions is tied to childhood leukemia. And another study published in the Journal of Environmental Health Perspectives links tiny particles in car exhaust to heart disease. These are just some of the studies and analyses that suggest we have a serious health threat right in front of us.
