Neodymium compounds, like all rare earth metals, are of low to moderate toxicity; however its toxicity has not been thoroughly investigated. Neodymium dust and salts are very irritating to the eyes and [[mucous membrane]]s, and moderately irritating to skin. Breathing the dust can cause lung [[embolism]]s, and accumulated exposure damages the liver. Neodymium also acts as an [[anticoagulant]], especially when given intravenously.
