Toxic studies were conducted with rats and guinea pigs to determine acute effects from single exposures to M60A1 tank-generated MIL-F-46162-Referee Arctic and Regular Grade diesel fuel smoke andor exhaust clouds under static airflow conditions. Emissions were disseminated with the Vehicle Engine Exhaust Smoke System VEESS and exposure periods ranged from 15-180 min in the case of the smokeexhaust emissions and 60-180 min with the exhausts. At attempted airborne concentrations of 10-12 mg 10,000-12,000 mgcu m of the Arctic and Regular Grade diesel fuel smokeexhaust mixtures and 0.07 mg1 70 mgcu m of the exhausts toxic signs excluding death were seen after 15- and 60-min exposures to the Arctic grade diesel fuel smokeexhaust emissions and death was observed at the 180-min exposures. The exhaust emissions from the same fuel caused toxic signs including death after 60- to 180-min exposures. Regular-grade diesel fuel smokeexhaust caused toxic signs and death in animals after 60- to 180-min exposures, while the exhaust clouds from the same fuel caused toxic signs at 60 min and toxic signs including death at 180 min. Significant respiratory changes are evidenced by pulmonary function tests were observed after 15-min exposures to the smokeexhaust emissions from either type of Referee Grade diesel fuel and similar effects were seen after 60-min exposures to the exhausts.
