How to Test for Antimony in Soil with XRF
Antimony doesn't appear on most environmental professionals' radar as often as lead or arsenic.
But at some sites, it's the primary contaminant of concern and needs systematic characterization.
Shooting ranges are the most significant antimony source in soil investigations. Lead bullets contain antimony as a hardening agent. As bullets impact berms and down-range soil, antimony co-deposits with lead and progressively accumulates in the shooting range soil environment.
At active ranges with years or decades of use, antimony concentrations can reach levels of regulatory concern alongside the better-known lead contamination.
Industrial sources include antimony-based flame retardants in plastics and textiles, antimony trioxide used in glass manufacturing, and certain battery and semiconductor applications. Sites associated with antimony ore processing or smelting can have elevated soil concentrations from long-term operations.
XRF, or X-Ray Fluorescence, detects antimony effectively at concentrations relevant to shooting range and industrial site investigations. Antimony's characteristic XRF signature is distinct and measurable at concentrations well above typical regulatory screening levels, making field XRF a practical tool for mapping antimony distribution across range berms and downrange soil areas.
At shooting ranges, the presence of lead and antimony in the same sample means a single XRF measurement characterizes both contaminants simultaneously. Berm soil sampling programs that use XRF can map the full spatial extent of both lead and antimony contamination in a single field effort instead of characterizing each element separately with sequential sampling programs.
For range operators facing closure, sale, or regulatory scrutiny, XRF-assisted site characterization provides a rapid, cost-effective way to understand the scope of contamination before committing your budget to a full investigation.
Antimony cleanup standards vary by jurisdiction and are less uniform than lead standards.
Saving your business money and time when it comes to regulations on soil contamination is easy using XRF.
Characterize contamination — lead and antimony together — in a single field effort.
