Multiple myeloma and engine exhausts, fresh wood, and creosote: a case-referent study.
The effect of potential risk factors for multiple myeloma was evaluated in a case-referent study encompassing 131 cases and 431 randomized referents, all alive. Information on exposure was obtained with questionnaires mailed to the subjects. An analysis of the material by means of the Miettinen confounder score technique resulted in a few rate ratios significantly exceeding unity--namely, occupational exposure to engine exhausts, creosote, and fresh wood. In view of other studies that suggest ionizing radiation as a risk factor, it was somewhat surprising that low-level gamma radiation from background exposure was less common among the cases than the referents.
