Wild plant species from three deserted antimony (Sb) mine areas in southern China were collected to measure eight metal(loid)s. Antimony, As (arsenic), Cd (cadmium), Cr (chromium), Cu (copper), Ni (nickel), Pb (lead), and Zn (zinc) concentrations in plants and soil were analyzed. The soils of the mining area was weakly alkaline and contained toxic levels of Sb, As, Pb, Cd, and Zn. Many plant species in the area (40 species and 19 families) have no clear signs of toxicity. The plants were divided into three categories (high, moderate, and low tendency to accumulate metals) based on their (ratio [RT], bioaccumulation factor [BCF], translocation factor [TF]) values. The plants with a high accumulation tendency exhibited the high potential to absorb Sb from contaminated soil; therefore, they can be used for the remediation or phytoremediation of Sb-contaminated soil.
从中国南方三个废弃锑矿地区采集野生植物物种，以测量八种金属（类）。分析了植物和土壤中的锑、砷、镉、铬、铜、镍、铅和锌的浓度。矿区土壤呈弱碱性，含有高浓度的锑、砷、铅、镉和锌，这些金属具有毒性。该地区的许多植物物种（40 种和 19 科）没有明显的毒性迹象。根据植物的比值（RT）、生物积累系数（BCF）和转移系数（TF），将植物分为三类（高、中、低金属积累倾向）。具有高积累倾向的植物表现出从污染土壤中吸收锑的高潜力；因此，它们可用于修复或植物修复受锑污染的土壤。
