Environmental Fate and Effects of Jet Fuel JP-8
Abstract
The fate of jet fuel JP-8 was studied in quiescent flask test systems containing water, water/sediment slurries and soil. For each treatment, killed samples were compared to active samples to assess the relative contributions of biodegradation and volatilization in removing JP-8. At appropriate time intervals, flasks were extracted with CS2 and analyzed by gas chromatography/mass spectrometry. In water and water/sediment slurries. the major removal process was evaporation. No significant differences were noted between active and sterilized flasks, indicating that biodegradation was not a major factor in removal of JP-8 under these test conditions. When removal in water alone was compared to removal in water/sediment slurries, greater losses were observed in water alone, indicating that the presence of sediment sequesters the jet fuel rendering it less susceptible to volatilization. Removal of JP-8 from active soil was not significantly different from removal in sterilized soil, indicating that in soil as well as water, biodegradation does not play a significant role in removal of jet fuel. Toxicity of JP-8 to microorganisms was assessed by measurement of glucose and hexadecane mineralization. Microbial activity in water was inhibited by JP-8 whereas activity in water /sediment slurries was enhanced by addition of JP-8.
