The Army has stopped producing so-called
"green" training rounds, because of research showing that the
bullets' main ingredient may be more toxic than previously thought. But that
element, tungsten, is also in an array of other ammunition and munitions, as
well. Which means all sorts of rockets, missiles, and anti-tank rounds may
present an environmental hazard and a health risk.
Tungsten was introduced to weaponry as an
alternative to depleted uranium, or DU -- itself an alleged toxin.
