The primary contaminants of interest were aluminum, singly and in combination with other inorganic compounds, and single components and complex fractions of a Wyoming crude oil. The species of consideration included the rainbow trout, the Atlantic salmon, the fathead minnow, and the striped bass. Several hypotheses were tested in the various studies within this research project. The primary hypothesis was the ambient pH can influence the availability and thus, the toxicity of chemical contaminants to fish. Preliminary studies tested the hypothesis that low pH is detrimental to the survival and growth of fish. The results of these studies were used to define no observable effect levels for pH for several species of fish. Other studies tested the hypothesis that the water soluble fraction of Wyoming crude oil is toxic to rainbow trout and fathead minnows. Additional studies tested the hypothesis that the availability and toxicity of aluminum and an inorganic contaminant mixture to fish are dependent upon ambient pH.
