The principal purposes of this study were to identify the radiation wavelengths and synfuel components responsible for photomutation and to compare photomutagenicity with carcinogenicity and Ames mutagenicity. Photomutation was measured as chemical- and radiation-dependent reversion of Salmonella typhimurium strain TA98 to histidine-independent growth. Treatments with Eastern US shale oil plus optically filtered sunlamp radiations showed that wavelengths shorter but not longer than approximately 400 nm were effective for photomutation. Shale oil with monochromatic 330 nm radiation was photomutagenic; 315 and 310 nm radiations were considerably less effective for photomutation; 300 nm radiation was ineffective; and shale oil reduced the mutagenic and lethal effects of monochromatic radiations from 270 to 295 nm.
