Lanthanide particles in the lung of a printer.
Lanthanides were extracted from the lung tissue of a subject with a history of potential exposure to carbon-arc lamp emissions in printing shops. The characterization of inorganic particles was performed by energy dispersive X-ray spectroscopy (EDS) on a transmission electron microscope (TEM) and laser microprobe mass analysis (LAMMA). Both techniques showed the presence of elemental Ce, La and Nd at concentrations higher than the average concentration measured in 41 other workers who had died of cancer at various sites. The lung content of other prismatic and compact particles did not show any statistically significant differences between the case and the control group.
