Predictive Environmental Health Risk Assessment for Military Operations: Preventing Long-Term Human Health Consequences

Abstract

Military operations involving hazardous chemical agents create environmental exposure pathways that may persist for decades after armed conflicts end. Although environmental toxicology has substantially advanced understanding of the persistence, transport, and biological effects of hazardous compounds, far less attention has been devoted to integrating this knowledge into military planning and operational decision-making. As a result, long-term consequences for civilian populations, military personnel, and ecosystems are often insufficiently considered before military actions are undertaken.

The Vietnam War provides one of the best documented examples of this challenge. Studies have demonstrated the long-term persistence of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in soils, sediments, aquatic ecosystems, and food chains following military herbicide application. Associations between historically contaminated regions and increased prevalence of congenital heart disease and other chronic disorders suggest that environmental impacts may persist for generations.

Rather than assigning historical responsibility, the proposed framework seeks to strengthen evidence-based military decision-making by incorporating long-term environmental health considerations into operational planning. Bridging the gap between environmental science and military decision-making represents an important interdisciplinary research priority for reducing long-term human suffering associated with future military operations. New models underdevelopment for environmental health risk assessment provide that path to be combined with military doctrine.
