| Abstract |
Concentrations of total chromium and Cr(VI) were measured by stationary and personal samplers at 15 chromium-plating plants, almost all the plants in Sweden employing more than 5 platers. The exposure range varied widely in hard plating, and 8h-TWA concentrations of <1 and up to 20-46µg/m3 were measured. In decorative chromium-plating exposure was almost always <0.5µg/m3. Near the baths and when handling workpieces about half the total exposure to Cr was to Cr(VI), in grinding work 10-20%. Exposure variations were investigated at 4 plants over a week: in more than 90% of the samples results varied by less than 50% from the corresponding median value. |
