*  Toxicological Information*
Toxicological Information:CHRONIC INHALATION EFFECTS: LONG-TERM
    INHALATION ANIMAL STUDIES INVOLVING A VARIETY OF INSOLUBLE
    PARTICLES HAVE RESULTED IN CHRONIC INFLAMMATION, LUNG FIBROSIS &
    LUNG TUMORS IN RATS. TUMORS WERE NOT O BSERVED IN SIMILAR STUDIES
    USING OTHERANIMAL SPECIES (I.E., MOUSE & HAMSTER). MOST INHALATION
    TOXICOLOGISTS FEEL THE TUMOR RESPONSE IS UNIQUE TO RATS & NOT
    RELEVANT TO HUMAN EXPOSURE. TREATED SYNTHETI C FUMED SILICA WAS NOT
    USED IN THESE STUDIES. THE RESEARCHERS WHO CONDUCTED THE ABOVE
    STUDIES FELT THE ADVERSE REACTIONS IN THE RAT WERE DUE TO HIGH
    EXPOSURE LEVELS OF INSOLUBLE DUSTS OVERWHELMING THE  LUNG CLEARANCE
    MECHANISMS.
