Ecological Soil Screening Levels for Antimony
forms of antimony (U.S. EPA, 1992) and are of the most interest in biological systems. The toxicokinetics and toxicity of the tri- and pentavalent forms vary, with the trivalent form considered to be more toxic. Ingested antimony is absorbed slowly, and many antimony compounds are reported to be gastrointestinal irritants.

Measurement of total antimony and antimony species in mine
The extraction of antimony species using citric acid should be a useful tool in the determination of antimony species available to plants. Plants commonly excrete carboxylic acids, including citric acid, into their rhizospheres. 36–39 Extraction with citric acid should give a good estimate of plant available antimony present in soils.

Antimony
Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.

Arsenic extraction and speciation in plants: Method
We compared four methods to extract arsenic (As) from three different plants containing different As levels for As speciation with the goal of developing a more efficient method, i.e., As-hyperaccumulator Pteris vittata at 459–7714 mg kg − 1, rice seedling at 53.4–574 mg kg − 1, and tobacco leaf at 0.32–0.35 mg kg − 1.

Extraction of Antimony
Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or
