| Abstract |
The frequency of sister chromatid exchanges and chromosome aberrations increased with the fume dose (particle concentration up to 200µg/ml). Particles from manual metal arc (MMA) welding were some 100 times more powerful than those from metal inert gas (MIG) welding. Chromium solubility was about 60 times higher in MMA fume particles than in MIG particles. The supernatant from the suspension of both fumes contained small amounts of manganese, nickel, iron and magnesium. Exposure to the supernatant increased the frequency of sister chromatid exchanges and chromosome aberrations. It is suggested that dissolved hexavalent chromium may be involved in the cytotoxic effect of stainless steel welding fume. |
