Elimination of Toxic Heavy Metals From Small Caliber Ammunition

摘要

The investigation of the chemical stability and mobility of tungsten as contained in non-lead bullets was conducted during FY 98. The environmental stability and mobility of the powdered tungsten as part of fragmented bullets was examined employing combinations of leaching and aging (corrosion) experiments. Materials used in the non-lead bullets were exposed to simulated environments (soil, solvents, temperatures, etc.) to determine what compounds would form and their solubility and mobility were examined.
