Chemical Mutagens

In an effort to gather information on the potential genetic hazards of existing or proposed energygenerating or -conversion systems, we have begun a correlated analytical and genetic analysis of a number of technologies. The work is divided into two phases: one deals with known compounds expected to occur in the environment through energy production, conversion, or use; the other deals with actual samples from existing or experimental processes. To approach the problems of coping with and testing large numbers of compounds, we set up a form of the "tier system." Operating units utilizing Salmonella, Escherichia coli, yeast, human leukocytes, mammalian cefls, and Drosophila have been initiated. Various liquid-liquid extraction methods and column chromatographic separations have been applied to crude products and effluents from oil-shale, coal-liquefaction, and coal-gasification processes. Mutagenicity of the various fractions is assayed by means of reversion of histidine-requiring auxotrophs of Salmonella typhimurium; comparative studies are-carried out with the other genetic systems. In order to incorporate metabolic activation of these fractions and compounds, rat liver homogenates (S-9) are used in the various assays. Results implicate chemicals occurring in the basic (ether-soluble) and the neutral fractions as potential genetic hazards. Chemical constituents of these fractions (identified or predkted) were tested individually for their mutagenic activity.
