Several recent studies have focused on toxic effects of various oil shale waters to freshwater algae (e.g., Cleave et al. 1980; McKnight et al. 1983). Algal bioassays are ecologically significant, since algae are the dominant primary producers in most freshwater environments. Furthermore, algae have been shown to be more sensitive to complex wastes than fish or invertebrates. Using a standard algal species provides a systematic approach to toxicant evaluation. One such species is Selenastrum capricornutum Printz, a freshwater unicellular green alga. A strategy to assess the hazards of complex effluents should include a battery of rapid, easily conducted, predictive tests within the larger framework of tier testing. This approach is used in this study to compare the growth and photosynthetic response of S. capricornutum to an oil shale by-product water and its organophilic and hydrophilic subfractions.
