Welding is among the most important and utilized industrial processes, and welders comprise one of the largest working populations. Welders experience higher rates of lung disease and cancer, yet the importance of specific air contaminants are not well understood. Epidemiologic studies have yielded equivocal results due to confounders and lack of exposure information. There is a need for exposure assessments to multiple fume components by process and material, but they must be designed to also quantify other predictor variables. There are current efforts under way to construct welding exposure databases, yet previous efforts are of very limited value due to quality and comparability problems. For exposure information to be useful and comparable, exposures and variables should be collected and recorded in a uniform fashion.
