Abstract:
Characterizing exposures to Chromium VI compounds is essential for understanding whether certain work processes may put workers in certain industries at greater risk for health effects than in others. The primary objective of this research study was to determine if the size of airborne hexavalent chromium particles a worker is exposed to has an effect on the amount of chromium actually taken up in the body of the exposed worker. Understanding the uptake, or dose, from exposure to CrVI is helpful for assessing worker risk. If uptake vaies sufficiently among different work process types, it may be appropriate to create regulations specific to work types rather than a blanket regulation.
