Fig. 9From: Pulmonary alveolar proteinosis in a catEnergy dispersive X-ray analysis of the alveolar content. Energy dispersive X-ray analysis of several particles (see Fig. 8) identified two principal elements: silicon (Si) and arsenic (As). A representative energy dispersive spectrum from one of these particles shows a high peak for silicon and multiple peaks for arsenic (including the small peak at 10.500 keV). Other elements were not always present in the particlesBack to article page
