Skin as a route of exposure and sensitization in chronic beryllium disease.(Research)

From: Environmental Health Perspectives | Date: July 1, 2003| Author: | Copyright information

Chronic beryllium disease is an occupational lung disease that begins as a cell-mediated immune response to beryllium. Although respiratory and engineering controls have significantly decreased occupational beryllium exposures over the last decade, the rate of beryllium sensitization has not declined. We hypothesized that skin exposure to beryllium particles would provide an alternative route for sensitization to this metal. We employed optical scanning laser confocal microscopy and size-selected fluorospheres to demonstrate that 0.5- and 1.0-[micro]m particles, in conjunction ...
