Ecological Soil Screening Levels for Antimony

Ingested antimony is absorbed slowly, and many antimony compounds are reported to be gastrointestinal irritants. Trivalent antimony is absorbed more slowly than the pentavalent form. Approximately 15 39% of trivalent antimony is reported to be absorbed in the gastrointestinal tract of animals (Rossi et al., 1987).

Antimony (Sb) is a hard, brittle, silver white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification.
