The federal government's responses to chemical exposures are generally for critical incidents—military pyridostigmine bromide during Gulf War,[1][2] Agent Orange in Vietnam,[4] burn pit exposures. The VA's toxic exposure research programs are significant but reactive.[3]
Since 2006, NIAID has distributed $6B+ for chemical, biological, and radiological countermeasures. BARDA has fueled R&D for defense against hazards through Project BioShield and advance market commitments. But these programs focus on acute weaponized threats, not chronic environmental exposures.[5]
The U.S. can track a novel flu strain in real-time but cannot detect widespread chemical damage until disease manifests years later.
