Pulmonary toxicity and lung tumorigenic potential of surrogate metal oxides in gas metal arc welding–stainless steel fume: Iron as a primary mediator versus chromium and nickel
Fig 6
Ability of alveolar macrophages to phagocytose E. coli GFP after exposure to GMAW-SS fume or metal oxides.
E. coli uptake by macrophages was quantified by flow cytometry. Data presented as percent change from sham (dashed line– 100%). *p<0.05 compared to sham.
