The munitions component, 1-nitroso-3, 5-dinitro-1,3,5- triazacyclohexane Mononitroso-RDX, was assessed for its relative irritant, skin sensitization, and mutagenicity potential. It showed no potential for eye or skin irritation in rabbits following a single application. It did not prove to be a skin sensitizer to guinea pigs. Mononitroso-RDX showed positive mutagenic activity in three of four in vitro bioassays. This finding, in addition to its implicating chemical structure, would earmark the chemical as a suspect mutagen andor carcinogen. Further testing is recommended to establish human risk. Interim protection and monitoring of operational personnel is also recommended until mutagenictoxicological risks are resolved.
