The answer to the diesel dilemma will be determined by the results of studies to determine whether diesel exhaust causes cancer. General Motors (GM) is promoting diesel usage although it has not completely committed itself because of the unfavorable results of tests conducted at Ames. The Ames results led to the EPA declaring it would expand federal chemical characterization and toxicological testing of diesel fuel, and to the recommendation against operating diesel engines in poorly ventilated areas. Diesel exhaust consists of gaseous and potentially hazardous particulates. The auto industry and the Department of Energy are searching for control technologies such as filters, catalysts and afterburners and fuel and engine modifications that will lower particle emissions. However, despite the present lack of such technology, GM is moving ahead. GM made this decision after a review of medical literature indicated that there was no significant health hazard. The EPA proposes to study the carcinogenic risk in a 3-pronged approach: in vitro, whole animal exposure, and epidemiology. However, EPA'S plans could be short-circuited by the tight 1979 deadline for results and by equipment and personnel shortages.
