||Occupational exposure to metals in the machining of copper-, chromium- and arsenic-treated wood

||Exposure was measured in two workshops where impregnated wood is machined. The chromium in the treatment solution is the most toxic form (chromium VI), but due to its reducing properties the cellulose in the wood tends to transform it during impregnation into what are probably trivalent components. As a result, worker exposure to chromium VI is minimal (at the limit of analytical detection). Generally, exposure to total chromium and copper is well below the limit values, both French and American. Only exposure to arsenic reaches significant levels in the two workshops. Although well below the current French limit value of 200µg/m3, it is above the limit value recently proposed in France (50µg/m3) and that adopted by ACGIH (10µg/m3). An efficient implementation of the prevention measures related to woodworking is sufficient for a good prevention of copper, chromium and arsenic related hazards.
