This final report summarizes the mutagenic studies conducted on SRC-II materials as part of the toxicological program under the Solvent Refined Coal (SRC) Process Contract for the period August 1, 1980 through March 31, 1982. Three Tasks were conducted on each of the following materials: coal slurry, middle distillate and stripper tower bottoms. One Task, a Saccharomyces/Mammalian-microsome mutagenicity study, involved the use of a eukaryotic microorganism capable of detecting mitotic crossing-over. Another Task, a dermal cytogenetics study in rats, concerned the analysis of cells from the bone marrow of rats dermally exposed to the test materials for the presence of chemically induced genetic alterations in chromosome number and structure. The third Task, the unscheduled DNA synthesis in primary rat liver cell cultures, involved the evaluation of the capability of the test materials to induce damage to the DNA. All studies were performed according to approved detailed protocols, FDA Good Laboratory practice Regulations, and quality assurance audits. The only positive mutagenic response to coal slurry and stripper tower bottoms was observed in the unscheduled DNA synthesis experiments. The only positive response to middle distillate was observed in the female animals in the dermal cytogenetics studies. However, the significance of this finding is uncertain in light of other stresses imposed on the animals.
