Introduction: Current dust exposure might be a more relevant metric than cumulative dust exposure when studying asthma and other respiratory conditions. In a previous retrospective cohort study of workers from a soft paper mill in Sweden, asthma was not associated with cumulative dust exposure, and the effect of current exposure was not addressed (1). Also, unpublished analyses of the same data revealed that chronic bronchitis was not associated with cumulative dust exposure. We re-analyzed these data to investigate whether current dust exposure predicted the onset of either asthma or chronic bronchitis. Based on a prior study of air samples from the mill, the dust contained no asbestos and less than 1% silica, and therefore fulfilled the criteria for a particle not otherwise regulated (PNOR) as defined by the USA Occupational Safety and Health Administration (OSHA). A final aim of this study was to investigate whether the OSHA PNOR standard of 15 mg/m3 total dust was protective for workers in a soft paper mill.
