LEAD AND ANTIMONY SPECIATION IN SHOOTING RANGE SOILS: MOLECULAR SCALE ANALYSIS, TEMPORAL TRENDS AND MOBILITY
Trainor, T.
SERDP Project ER-1770, 98 pp, 2017

The objective of this project was to provide a detailed analysis of the changes in lead (Pb) and antimony (Sb) speciation that occur over time as bullet fragments weather in shooting range impact-berm soils. Most bullet alloys are composed of about 90% Pb with up to 5% Sb and lesser amounts of Cu, Ni, Zn, and other metal(loid)s. Bullet fragments found in berm soils associated with training activities are highly susceptible to oxidation and weathering processes that can generate mobile and bio-available forms of metal(loids), which calls for improved understanding of how the speciation of the key metal(loids) changes under typical soil/geochemical conditions. https://www.serdp-estcp.org/content/download/46516/435214/file/ER-1770%20Final%20Report.pdf
