Environmental Fate and Biological Consequences of Chemicals Related to Air Force Activities
Abstract
Terrestrial ecosystems containing intact soil cores have shown effective utility for evaluating vertical migration of hydrocarbon chemicals in soil. Sampling probes containing selective adsorbants have demonstrated that the hydrocarbon components of jet fuels can be recovered for analysis. Gas chromatographic techniques are very sensitive for tracing and quantifying hydrocarbon movement in the soil cores. Soil microarthropods are very sensitive organisms for testing the toxicity of jet fuel components. Carbon dioxide evolution into the headspace above the jet fuel treated soil cores increases and may be an indicator of stress to soil flora and fauna. The paths and rates of transport of aqueous leachates through soil cores change dramatically with time because of fauna borings and tunneling as well as by other physical causes. The hydrocarbon components of jet fuels migrate to varying depths and quantities independent of one another and appear to be independent of aqueous leachate movement. Microbial degradation of Model JP-5 jet fuel appears to have occurred in culture flasks containing jet fuels inoculated with cultures of soil organisms.
