The Dahlgren Decon solution will neutralize a wide range of substances, from toxic industrial chemicals and materials to chemical warfare and biological agents. The new decontamination solution has a moderate pH and does not generate toxic-byproducts.
Surfactant prevents this collapse by reducing the surface tension of the fluids that line the lungs and helping to equalize the pressures between large and small air spaces. Surface tension is a measure of the attraction molecules of a fluid have for each other.f the surface tension is lowered, the attraction among molecules of the fluid is decreased and the surface area of the fluid increases. For example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out.
