Occupational exposure to diesel exhaust multiplies risk of lung cancer for miners

Researchers from the US American National Institute for Occupational Safety and
Health (NIOSH) and the National Cancer Institute (NCI) have found that miners
exposed to diesel exhaust on the job face a much higher risk for lung cancer.

In a cohort mortality study and a nested case-control study, both recently
published in the Journal of the National Cancer Institute, researchers analyzed
lung cancer mortality among miners exposed to diesel exhaust, controlling for
smoking, exposure to radon, and other risk factors and contaminants. The
authors, including OSHA Industrial Hygienist Joseph Coble, found an
approximately three-fold increase in the risk of dying from lung cancer among
the most heavily exposed workers.

Diesel exhaust is a pervasive airborne contaminant in workplaces where
diesel-powered equipment is used. More than one million workers are exposed to
diesel exhaust and face the risk of adverse health effects, ranging from
headaches and nausea to cancer and respiratory disease.
