Abstract
Methods are described for detecting chemical warfare agents that contain organophosphorus compounds. Compositions containing either (1) a sufficient amount of phosphonate ester hydrolase with an alkali agent or (2) a sufficient amount of phosphonate ester hydrolase, a sufficient amount of organophosphorus hydrolase and a sufficient amount of a organophosphorus acid anhydrolase, may be utilized to test for organophosphorus compound-containing chemical warfare agents. These enzymes will react with such chemical warfare agents to produce degradation products, specifically phosphonate esters.
