Abstract : In the second year of the AFOSR grant to examine the sublethal effects of water soluble fraction (WSE) of JP-4 jet fuel we have completed most of the work on the petroleum derived JP-4. Fractionators have been built and used to generate constant concentrations of the WSE JP-4 that were used to determine the lethal and sublethal effects on bluegill sunfish (Lepomis macrochirus) and selected aquatic invertebrates. The dynamic 96 hour LC50 for the WSF JP-4 for the bluegill was determined to be 26.2%. (This is percent of the maximum soluble amount of JP-4.) The concentration of the WSE JP-4 which causes a detectable shift in the ventilatory functions (rate and amplitude) was determined to be 5.1% WSE. In the second year of research producing cultures of aquatic invertebrates were established, flow-through test systems were designed and constructed, and toxicity tests with the water soluble fraction (WSE) of petroleum JP-4 were begun with 3 invertebrates, the oligochaete, Aeolosoma headleyi, a benthic collector gatherer; the cladoceran Daphnia pulex, a planktonic filter-feeding crustacean; and, the dipteran Paratanytarsus parthogentica (Freeman) (= Tanytarsus dissimilis Joh.), a substrate associated collector gatherer.
