Study says diesel emissions can increase risk of cancer three-fold

Date Posted: 2012-03-09

A landmark government health study provides evidence that the diesel engine exhaust that pervades California highways could be causing cancer at a greater rate than previously known. The study says miners exposed to diesel engine exhaust are three times more likely to contract lung cancer and die, and that a similar increased risk applies to people from smoggy, urban areas such as Southern California who live near freeways or commute to work. The long-term study, carried out by the National Cancer Institute and the National Institute for Occupational Safety and Health, is described by scientists and advocacy groups as the most thorough study on the topic ever released. The study was published in the current edition of the Journal of the National Cancer Institute.
