ABSTRACT: Recent research has suggested that increased industrial and technological utilization of antimony and bismuth necessitates greater research to determine the soil and water chemistry and the environmental risks associated with these elements. The near-total soil profile concentrations of antimony and bismuth were determined for key soil series across southeastern Missouri. The antimony concentrations ranged from 0.65 to 0.08 mg kg−1, whereas the bismuth soil profile concentrations ranged from 0.92 to 0.03 mg kg−1. Most pedons showed antimony concentrations ranging from 20 to 30 mg kg−1, whereas bismuth concentrations were commonly 10 to 20 mg kg−1. For soils having argillic horizons, antimony and bismuth concentrations were greater for the illuvial horizons than the eluvial horizons, whereas Entisols, Inceptisols, and one Vertisol showed rather uniform antimony and bismuth concentrations, features paralleling the soil texture distribution. Both antimony and bismuth showed significant correlations with iron.
