Ecological Soil Screening Levels for Antimony

Antimony (Sb, stibium) is a semi-metallic element that belongs to group (VA) of the periodic table and shares some chemical properties with lead, arsenic, and bismuth (U.S. EPA, 1992). In nature, antimony is associated with sulfur as stibnite. Antimony also occurs in ores with arsenic, and the two metals share similar chemical and physical properties. Antimony is a common component of lead and ...
