Long-term inhalation animal studies involving a variety of insoluble solid particles have resulted in chronic inflammation, lung fibrosis and lung tumors in rats. Tumors were not observed in similar studies using other animal species (i.e., mouse and hamster). Most inhalation toxicologists feel the tumor response is unique to rats and not relevant to human exposure. Synthetic fumed silica was not used in these tests. 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 (lung overload phenomenon) and is not the result of specific chemical effect of the particulate tested. This effect is not expected to occur from occupational exposure to synthetic amorphous silica.
