Assessing chemical exposures during military deployments

Before the first Persian Gulf War, military chemical concerns were focused on life-threatening/performance-impairing effects from exposures to chemical warfare agents. Now, hazards of concern include both high and low levels of chemical warfare agents and toxic industrial chemicals in air, soil, and water. The types of health effects considered have expanded to include both immediate, acute effects (mild and severe), and delayed or chronic outcomes. Because federal exposure standards are not applicable to deployed personnel, the U.S. Army Center for Health Promotion and Preventive Medicine established military-specific exposure guidelines in Technical Guide 230, Chemical Exposure Guidelines for Deployed Military Personnel. Methods used to develop the guidelines address toxicological data limitations, uniqueness of military populations and exposure scenarios, and a risk assessment process compatible with existing military operational risk management doctrine. The Technical Guide 230 helps ensure chemical hazards are addressed in various deployment scenarios.
