Scanning Electron Microscope Images of Particulate Matter in Lung Tissue

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 18, 2025 | Last Modified: 20200929
We developed and tested a new method for in situ characterization and distribution of inorganic particles in biopsied lung tissue from three diverse human subject groups using field emission scanning electron microscopy with an energy dispersive analyzer. Secondary and backscattered electron images were acquired to document the size and location of inorganic particulate matter in areas of lung tissue biopsy sections.
