This final report summarizes the acute toxicity studies conducted on SRC-II materials as part of the toxicological program under the Solvent-Refined-Coal (SRC) Process Contract for the period August 1, 1980 through March 31, 1982. Three materials were studied in this part of the program: coal slurry, stripper tower bottoms, and middle distillate. The materials were evaluated for: toxicity when administered orally in a single dose to rats; toxicity when administered dermally in a single dose to the intact and abraded skin of rabbits; the eye irritation potential when instilled into the rabbit eye; and, the sensitization potential when applied to the intact skin of the guinea pig. In addition, the middle distillate was also evaluated for aspiration hazard and toxicity when administered once into the oral cavity of rats, and the acute inhalation toxicity of a vapor/aerosol mixture when administered to rats by whole body inhalation exposure for four hours. All studies were performed according to approved detailed protocols, FDA Good Laboratory Practice Regulations, and quality assurance audits. Based on the results of these studies, it has been concluded that the coal slurry is not acutely toxic by either the oral or dermal route, must be classified as a mild eye irritant, and may on occasion cause slight dermal sensitization. The stripper tower bottoms is not acutely toxic by either the oral or dermal route, is not an eye irritant, and may on occasion cause slight dermal sensitization. Middle distillate appears to show moderate toxicity by the acute oral route but no acute dermal toxicity, must be classified as a mild eye irritant and may on occasion cause slight dermal sensitization. Middle distillate was also deemed to be an aspiration hazard as would be expected and showed moderate toxicity by the acute inhalation route.
