Demilitarization of Conventional Ordnance: Priorities for Data-Base Assessments of Environmental Contaminants

摘要

The primary goal of this study has been to identify a set of environmental by-products from the demilitarization of conventional ordnance that should be the subject of more detailed data-base assessments. In order to rank the by-products according to their potential health risks, estimates were made of the contaminant releases associated with destructive techniques (e.g., open burning, open detonation, and incineration) and nondestructive techniques (e.g., filler recovery and reuse). Estimates of the types and quantities of propellants, explosives, and pyrotechnics in the demilitarization inventories of various installations in the U.S. were made. To calculate hypothetical doses to man from contaminant releases, a multimedia compartmental model was used to calculate the concentrations of contaminants in water, soils, air, and biota. Based on an analysis of the doses and toxicity data for the compounds, several substances were recommended for further analysis, including DNT, TNT, and RDX and their degradation products in the environment. Other compounds are dibutyl phthalate, diphenylamine, HMX, and tetryl.
