| Abstract | Carbon adsorption, solvent extraction, steam distillation and flash evaporation techniques were used to remove organic fractions from oil refinery effluents. Toxicity of organic fractions was evaluated by bioassay with fathead minnows (Pimephales promelas) and Daphnia (Daphnia magna). Demonstrably toxic fractions were subjected to gas chromatography and combination gas chromatography - mass spectrometry analyses. Concentrations of toxic heavy metals in the refinery effluents were analyzed by atomic absorption spectrophotometry. The flash evaporation technique removed most of the acute toxins from the effluent samples. Compounds tentatively identified were cresol, dimethyl phenol or ethyl phenol, heneicosane, docosane, tricosane, and pentacosane. It was found that the combined concentration of several of the heavy metals could be deleterious to aquatic organisms. (Author) |
