Diesel Exhaust in Miners Study (DEMS)

In March 2012, the National Cancer Institute (NCI) and the National Institute for Occupational Safety and Health (NIOSH) completed a retrospective cohort mortality and nested case-control study of 12,315 workers at eight non-metal mining facilities to investigate risk of lung cancer in relation to quantitative measures of historical exposure to diesel exhaust, after taking into account smoking and other lung cancer risk factors. Elevated mortality from other causes among diesel exhaust-exposed miners was examined as well. An extensive effort to characterize current and historical exposures to diesel exhaust and to develop estimates of personal exposures was an intrinsic part of the study. The methods for this effort were published in five papers in the Annals of Occupational Hygiene. In 2012, results from the NCI-led case-control study and the NIOSH-led cohort study were published in the Journal of the National Cancer Institute.
