In Vitro Mutagenicity Testing of Ohio Coal-Derived Materials

In the effort to meet United States energy needs from domestic sources, coals of many origins are being studied for their feasibility in industrial and home heating use. The Ohio Coal Research Laboratory Association, a consortium of 12 university laboratories, has as its objective the study of methods by which Ohio coals may be used productively. Of particular interest is the application of technologies to the efficient use of high-sulfur coals by this region’s basic industries. Our concern has been with health effects of increased coal use. It is likely that more extensive coal combustion, particularly high-sulfur coal, would add to the air pollution burden. Processing coal to cleaner-burning fuels, however, is also not without risks. For example, it is known that workmen employed in the carbonization of coal for coke or for generation of gas have higher than expected risks of cancer at various sites (Lloyd, 1971). Likewise, processing of coal to liquid fuels has been associated with increased cancer risk, and carcinogenicity of coal-derived liquids has been demonstrated experimentally (Weil and Condra, 1960; Ketcham and Norton, 1960; Battelle, 1979). Considering the potential biohazards of using coal in whatever form, the necessity for evaluating risks at an early stage in technological development becomes obvious.
