    11 - Toxicological Information
    ________________________________________________________________________
    SIGNS AND SYMPTOMS OF EXPOSURE
    To the best of our knowledge, the chemical, physical, and
    toxicological properties have not been thoroughly investigated.
    Symptoms of exposure may include burning sensation, coughing,
    wheezing, laryngitis, shortness of breath, headache, nausea, and
    vomiting. Inhalation may result in spasm, inflammation and edema
    of the larynxand bronchi, chemical pneumonitis, and pulmonary
    edema. Material is extremely destructive to tissue of the mucous
    membranes and upper respiratory tract, eyes, and skin. Rare
    earth compounds may cause delayed blood clotting leading to
    hemorrhages. Inhalation of rare earths may cause sensitivity to
    heat, itching, and increased awareness of odor and taste.
    ROUTE OF EXPOSURE
    Multiple Routes: May be harmful by inhalation, ingestion, or
    skin absorption.
