From: Comparison of stainless and mild steel welding fumes in generation of reactive oxygen species
Oxygen consumption in welding fume stimulated RAW 264.7 cells. Incubation mixtures contain 3 × 106 RAW 264.7 cells + 500 μg/ml welding fume sample. Data presented are means of ± S.D. for 4 sets of experiments. (*) indicate a significant increase in oxygen consumption compared to control. (+) indicate significant difference between metal types at the same sizes. (P < 0.05)
