People exposed to diesel fuel exhaust are at risk of getting cancer. That is the conclusion of a two new studies conducted by a cancer group that's part of the World Health Organization. For more than two decades, diesel engine exhaust has been classified as a probable cancer-causing agent. The WHO says the new studies show a direct link between exposure to diesel fuel exhaust and the disease.
The findings could pressure the government to put stricter limits on emissions and require greater protection for workers exposed to diesel exhaust.
