Evaluation of the Potential for Groundwater Transport of Mutagenic Compounds Released by Spent Oil Shale

摘要

The potential mutagenicity of aqueous leachates from coal, raw oil shale, and the spent shale resulting from two processes was tested. Specifically, an Ames salmonella microsomal bioassay was used to test for chemical mutagenicity. Spent oil shales from the Paraho and TOSCO II processes, a raw shale from Anvil Points, and a composite coal sample from the Wasatch plateau were extracted with double deionized water and organic solvents. Of the tests, only organic solvent extraction of the TOSCO spent shale resulted in a mutagenic response.
