Researchers have yet to find a practical means of removing the bang from ammonium nitrate, the fertilizer used to blow up a federal building in Oklahoma City, or to put identifying chemicals in explosives, the National Research Council says.
“There is no one single measure that can make the nation safe from terrorist bombing,” Marye Anne Fox, a chemistry professor at the University of Texas and co-chair of the council’s study committee, said Wednesday. The panel suggested that the government toughen controls on the sale and distribution of explosives and ammonium nitrate and that researchers continue to search for chemical ways of identifying and detecting explosives.
