The Kalgoorlie goldminers cohort was exposed to significant amounts of diesel fumes from underground mining machinery.
Diesel equipment was introduced into the WA gold mines in the 1950s and diesel emissions were first classified as a probable carcinogen in 1989 (Health Effects Institute, 1999).
Diesel particulates are also thought to represent a large proportion of modern day air pollution, which has been shown to increase the rates of death and rates of admission to hospital in most countries of the world (Health Effects Institute, 1999).
Quantitative estimates of diesel exposures in the Kalgoorlie goldminers cohort will support the examination of dose-response effects of diesel on health.
