The activities of the Toxic Hazards Research Unit THRU for the period of June 1970 through May 1971 are reviewed. Modification of the animal exposure facilities primarily for improved human safety but also for experimental integrity and continuity are discussed. Acute toxicity experiments were conducted on hydrogen fluoride HF, hydrogen chloride HCl, nitrogen dioxide NO2, and hydrogen cyanide HCN both singly and in combination with carbon dioxide CO. Additional acute toxicity experiments were conducted on oxygen difluoride OF2 and chlorine pentafluoride ClF5. Subacute toxicity studies were conducted on methylisobutylketone and dichloromethane methylene dichloride. The interim results of further chronic toxicity experiments on monomethylhydrazine MMH are also described.
