Heavy diesel exhaust linked to lung cancer

Heavy diesel exhaust linked to lung cancer - Health - Cancer - msnbc.com:


There's new evidence that exposure to exhaust from diesel engines increases the risk of lung cancer.

Diesel exhaust has long been classified as a probable carcinogen. But the 20-year study from the National Cancer Institute took a closer look by tracking more than 12,000 workers in certain kinds of mines — facilities that mined for potash, lime and other nonmetals. They breathed varying levels of exhaust from diesel-powered equipment, levels higher than the general population encounters.
