The potential mutagenicity of aqueous leachates from spent oil shale is discussed. Additional mutagenicity testing was also done on raw shale and coal. The 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. Only organic solvent extraction of the TOSCO spent shale resulted in a mutagenic response. The lack of mutagenic response to organic extracts of Paraho spent shale was unexpected and was probably due to higher than typical temperatures at which it had been retorted. Using TOSCO spent shale leachate and the organically extracted mutagen, a partion relationship between the spent shale and leachate water was developed. The mutagen was found to have a fairly high affinity for spent shale. Based on this it was estimated that mutagenicity of the TOSCO spent shale leachate will be low (in the range of chlorinated waste water), however it will require many pore volumes to leach out of a pile potentially resulting in a chronic longterm problem.
