Fig. 1From: The utility of electron microscopy in detecting asbestos fibers and particles in BALF in diffuse lung diseasesAn example case of the analysis by electron microscopy. The fibers and particles were divided into ferruginous bodies (a), uncoated fibers, and particles (b) based on the morphological findings. A mineralogical analysis revealed that the ferruginous body contained magnesium (Mg) and silicon (Si), calcium (Ca) and iron (Fe), suggesting it to be an actinolite asbestos body (c). Particles containing Fe and phosphorus (P) (d)Back to article page
