Transmission electron microscopy images of lungs treated with PM-b. At day 28, some parts of the lung tissues were fixed and subjected to TEM. PM-b particles were observed in alveolar macrophages and alveolar capillaries. P: vacuoles containing PM-b particles; M: alveolar macrophage; C: alveolar capillary; Arrow: pinocytotic vesicle; Arrowhead: mitochondria. Scale bar: 20,000 nm and 2000 nm in low and high magnification images, respectively
