Abstract

The chemical composition and crystalline structure of silicate particles engulfed in human alveolar macrophages were investigated by transmission analytical electron microscopy. A crystalline ZrSiO4 and an amorphous Si2AlO4 particle were identified. Small crystalline Fe microparticles (2–4 nm), which are likely ferritin molecules, were found concentrated mainly at the amorphous particle-tissue interface.
