After a review of over 30 years of studies, the Centers for Disease Control concluded that children living near high-volume roads and highways were 50% more likely to suffer from childhood leukemia. The cancer risk is linked to postnatal exposure.
In the April issue of the American Journal of Preventative Medicine, researchers for the CDC explain how they examined all the published studies concerning traffic air pollution risks from 1980 to July of 201. Out of nine relevant studies, seven, covering approximately 8,000 children, reveled a correlation between exposure and leukemia.
"The review found that children diagnosed with leukemia were "50% more likely to live near busy roads than children without leukemia," said Vickie Boothe, a CDC health scientist and lead author of the Journal article. "While the study found a link, it does not prove that living near a busy road causes leukemia."
