Launch Area Toxic Risk Analysis Program (LATRA) Toxicology Review

摘要

The toxic cloud corridors generated during normal and catastrophic rocket launchscenarios and the possible human health effects are a source of concern to the US Air Force. Therefore, a literature search of three species of rocket emissions was performed to identify health effects information useful to HQ Space Command for managing the risk from these toxic clouds. The literature retrieved on the three compounds of interest, hydrogen chloride (HCl), nitrogen oxides (NOx) and nitric acid (HNO3), was evaluated to identify the toxic responses associated with inhalation from such exposures. Animal and human data generated in acute toxicity studies were assessed, indicating the respiratory track was the target of exposure to these compounds. Based upon the available toxicity information, acceptable levels of exposure were proposed. The toxicological information data bases under review and proposed recommendations were presented for consideration to the National Research Council National Academy of Science, Committee on Toxicology.
