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 8
Total tumor number per mouse lung following exposure to CO or MCA and a metal oxide or sham.
Bars represent lung tumor multiplicity (mean tumor number/mouse lung and includes mice with no tumors) for each group. *p<0.0001 compared to MCA/sham.
