Bioluminescent toxicity assay of synfuel by-product waters
Large amounts of complex by-product waters, potentially toxic to biological systems, are generated during in situ recovery of fuels from oil shale, coal, and tar sand deposits. Since these by-product waters may contain a broad spectrum of organic and inorganic pollutants, analysis of individual compounds may not always be practical. Separation of complex by-product water into environmentally interpretable hydrophilic (HP) and organophilic (OP) fractions can, however, provide a useful approach for initial toxicity evaluation. The Microtox assay was developed by Beckman Microbics Operations. For this assay, reduction of bacterial luminescence upon exposure to potential inhibitors was used as an index of toxicity. This paper presents results of the Microtox assay on eight whole waters and their HP and OP fractions, derived from oil shale, coal, and tar sand recovery processes.
