摘要

The purpose of this technical report is two-fold. First, this technical report presents the results of a sensory irritation assay conducted in male Swiss-Webster mice exposed to different concentrations of hydroprocessed esters and fatty acids (HEFA) bio-based jet fuels, HEFA-Camelina (HEFA-C) and HEFA-Tallow (HEFA-T). The mice were exposed via a modified nose- only plethysmograph tube to each fuel, administered as an aerosol/vapor combination. For HEFA-C, the predicted RD50 (50 percent reduction in respiratory rate) was greater than 11,755 mg/m3. For HEFA-T, the predicted RD50 was greater than 13,306 mg/m3. This technical report also summarizes toxicity data for HEFA fuels, including HEFA-C, HEFA-T and a HEFA fuel with a feedstock of mixed animal fats and oils (HEFA-F). HEFA toxicity data are then compared with toxicity data from synthetic paraffinic kerosene (SPK) alternative jet fuel and petroleum derived JP-8. The toxicity data are used to develop a comparative occupational exposure limit (OEL) for HEFA fuels that concurs with the current JP-8 OEL (200 mg/m3).
