Scientists 'tame' deadly white phosphorous



WASHINGTON - Scientists have found a way to store and transport the highly dangerous chemical white phosphorous, which becomes flammable upon contact with air, according to a study released Thursday.
Notorious for its propensity to burst into flame, white phosphorous often is used on the battlefield to create smokescreens and as an incendiary substance in bombs, artillery and mortars.

But the chemical also has a useful application as a component of weed killers, insecticides and fertilizers, making its safe storage and transport critically important for industry.
Jonathan Nitschke, of Cambridge University in Great Britain and a lead author of a study in the June 26th issue of the journal Science, reported that a team of British and Finnish scientists have created a "container molecule" capable of rendering the chemical harmless indefinitely until a signal agent -- benzene -- is applied to release it.
"It is foreseeable that our technique might be used to clean up a white phosphorous spill, either as part of an industrial accident or in a war zone," said Nitschke.
Untreated, white phosphorous can "inflict grievous harm" and "poses a major environmental hazard," Nitschke wrote in Science.
He said the discovery can be extended to the transport other hazardous chemicals.
