Abstract:

Subchronic 90-day inhalation studies were conducted to compare the toxicity of Petroleum and Oil Shale derived JP-5 jet fuel. Beagle dogs, Fischer 344 rats, and C57BL6 mice were continuously exposed to JP-5 at concentrations of 150 mgm cum and 750 mgcum 3. Unexposed control groups were also maintained. All dogs and a portion of each rodent group were sacrificed and examined at exposure termination. Remaining rodents were held for observation up to 21 months postexposure. The most significant exposure related effect occurred in male rats, where JP-5 produced nephropathy characterized by hyaline droplets, necrosis, and intratubular casts. Accentuated tubular degeneration and medullary mineralization were noted in exposed rats held for long-term postexposure observation. Female rats were free of significant JP-5 related renal damage. Consistent with the pathologic changes in male rats exposed to 750 mgcu m 3 were increased kidney weight and increased serum creatinine and BUN levels. Reduced body weight gains also occurred in male rats exposed to JP-5. No pathologic lesions were observed in dogs exposed to JP-5. Hepatocellular vacuolization and fatty change occurred in mice exposed to JP-5 from either source and in rats exposed to Shale JP-5. The results of this study suggest that there are no substantial differences between Petroleum and Shale JP-5.
