This study compared the effects of water soluble fraction WSF of petroleum derived P JP-4, a common military and civilian jet fuel, and shale derived SD JP-4 on survival, growth, ventilatory rate, preference-avoidance behavior, and tissue of the bluegill sunfish Lepomis macrochirus to determine possible interrelationships and to determine which procedures might be possible interrelationships and to determine which procedures might be most descriptive of sublethal stress. Comparative studies were also run using invertbrates and microbial communities. In acute tests, fish were generally more sensitive to jet fuel WSFs than invertebrates. This is consistent with previous observations on the relative toxicity of the major components, benzene and toluene. No major discrepancies occurred in the chronic sensitivities of fish and invertebrates. Fish ventilatory response appeared to be the quickest and most efficient of the sublethal tests used and provided a reasonable estimate of a chronic effect level. Microbial communities responded to low levels of jet fuel exposure, but toxicant related effects would probably be short-lived and of limited consequence in field exposures.
