Microscopic appearance of lungs (A-E) and lymph node (F). A – Control. B – MWCNT, 2.5 mg/m3, study day 4: Microgranuloma, particles in the lesion and inside of alveolar macrophages. C – Graphene, 10 mg/m3, study day 7: Microgranuloma, particles within the lesion. D – Graphite nanoplatelets, 10 mg/m3, study day 4: Particles inside of alveolar macrophages. E – Carbon Black, 10 mg/m3, study day 4: Particles inside of alveolar macrophages. F – MWCNT, 2.5 mg/m3, study day 25: Mediastinal lymph nodes with macrophages containing black particles (arrow).
