Toxic studies were conducted with rats, mice, and guinea pigs to determine acute effects from single exposures to M60A1-tank-generated DF2 and DF1 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 to 300 minutes. At attempted airborne concentrations of 10.0 to 12.0 mgi 10,000 cu.m to 12,000 cu.m of the DF2 and DF1 smokeexhaust mixtures and 0.2 mg1 200 mgcu.m of the exhausts, toxic signs excluding death and lung compliance changes were observed after 15-minute exposures. Death and pathological abnormalities of the lung were seen after 16-minute exposures to DF2 smoke andor exhaust. Exposures to DF1 smokeexhaust showed lung pathology and death by 120 minutes while death and turbinate lesions were observed in animals exposed to DF1 exhaust for 60 minutes. Experimental evidence suggests that a principal toxic component for each type of cloud, regardless of the fuel source, is an inherent component of the generated exhausts. Author
