Breaking down chemical weapons

The formulas are based on ingredients found in foods, cosmetics and other consumer products.

George Wagner and colleagues explained that chlorine- and lye-based decontamination agents are already potentially hazardous and can react with chemical weapons and materials in the environment to form new toxic substances.

Decontaminating a large area could produce runoff that is harmful to people and the environment.

To solve that problem, military scientists developed the Decon Green suite of decontamination agents. The main ingredients in each Decon Green formula are peroxides, which are in many household cleaners and whitening toothpaste.

To bolster their effectiveness, the peroxides are mixed with bicarbonates or other non-toxic bases to produce peroxyanions − highly reactive ions that can completely break down chemical weapons such as nerve gas.

Wagner described putting the new cleaning agents through an exhaustive battery of tests. His team concluded that each formula can break down toxic chemicals, rather than just washing them away.
