| A major concern of this study was the characterization of organic residue associated with processed oil shale, in order to aid in the evaluation of the potential impact of oil shale development. A forecast of oil shale development in the White River Basin (Utah and Colorado) has been projected and hydrological and geological parameters pertinent to estimations of polycyclic aromatic hydrocarbon (PAH) flux have been focused.; Organic residues from processed oil shales have been characterized in this study with specific attention to PAH. Processed oil shale samples from the Union B, Paraho and Tosco II processes have been extracted by using organic solvents in a soxhlet apparatus and by mixing shale samples with water (characterization of in situ shales, as mined shales and alluvial samples are also included). Reported organic chemistry isolation and identification regimes (applicable to gas, liquid and solid samples) are summarized in a tabular format ((TURN)50 examples). Selected 3 through 6 ring aromatic hydrocarbons are also characterized in a tabular format ((TURN)100 examples).; More than 100 organic compounds from processed oil shales were identified by gas chromatography coupled with mass spectrometry (GC/MS). Four and 5 ring PAH (fluoranthrene, pyrene, triphenylene, benz(a)anthracene, chrysene, benzo(e)pyrene, perylene and benzo(a)pyrene) were found to be benzene extractable from processed shales in concentrations ranging from < 1 to > 50 ppb (weight of each PAH:weight shale). These PAH were available in water extracts below their respective solubilities. |
