Hatch, G., E. Boykin, F. Miller, AND J. Graham. EFFECTS OF FLY ASH AND ITS CONSTITUENTS ON SENSORY IRRITATION IN MICE. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-81/396 (NTIS PB83188946).
Description:
Sensory irritation caused by fly ash from oil-fired (OF), fluidized bed coal (FB) combustion and conventional coal (CC) combustion power plants, and from Mt. St. Helens volcano (VA) was studied in mice. The irritating sensation due to contact with fly ash or its constituents was quantitated by observing a characteristic flexing of the dorsal musculature of the mouse following intraperitoneal injection of the ash suspension. Construction of dose-effect curves was based on the percentage of animals showing a positive response at each ash concentration.
