Lead and Antimony Speciation in Shooting Range Soils: Molecular Scale Analysis, Temporal Trends and Mobility

Abstract

The objective of this project was to provide a detailed analysis of the changes in lead (Pb) and antimony (Sb) speciationthat occur over time as bullet fragments weather in shooting range impact berm soils. This project is motivated by the factthat most bullet alloys are composed of about 90% Pb with up to 5% Sb, and lesser amounts of Cu, Nit Zn and other metal(loid)s. Bullet fragments found in berm soils associated with training activities are highly susceptible to oxidation andweathering processes that can generate mobile and bio-available forms of these metal(loids). This requires a detailedunderstanding of how the speciation of the key metal(loids) changes under typical soil/geochemical conditions.
