Environmental Impact to the Chemical Signature Emanating from Buried UnexplodedOrdinance

摘要

Detecting the presence of buried unexploded ordnance (UXO) using chemical vaporsderived from the main charge explosive has been considered possible with advances in sensitivity and selectivity of emerging chemical sensing technologies. Understanding the environmental impacts to the chemical signature is critical, as environmental factors have a dramatic effect on the source release, transport, phase, transfers and degradation in soil systems. This project established several tasks to evaluate the environmental impact to the chemical signature from buried UXO. These tasks included simulation model development and utilization to evaluate the interdependent physico-chemical transport phenomena in near surface soils, fundamental property measurement for those parameters needed in the simulation model that had insufficient or poor quality data, and laboratory-scale experiments that produced data for comparison to simulation model results. This project also sponsored work to produce data on the chemical release characteristics of a small subset of ordnance and UXO, and to determine the chemical residues in the field adjacent to actual UXO.
