A study about topsoil antimony distribution and mobility from the soils to the biomass has been afforded in three abandoned Sb mining areas located at Extremadura. Physico-chemical characteristics of the soils and total antimony levels were measured in soils and autochthonous plant species (Cytisus striatus, Cistus ladanifer and Dittrichia viscosa). Comparison with corresponding values in reference areas isolated from the mining activities is discussed. Antimony mobility in the soils was estimated by measuring the water extractable fraction; low results were obtained for the three soil areas, with no statistical differences. Plant ability to accumulate antimony was estimated by use of plant accumulation coefficients (PAC). Seasonal (spring vs. autumn) effects on the antimony content in the plant species. Cytisus striatus from Mari Rosa mine presented antimony excluder characteristics, whereas Dittrichia viscosa specimens growing in San Antonio mine showed a significant antimony bioaccumulation.
一项关于埃斯特雷马杜拉三个废弃锑矿区表土中锑的分布以及从土壤到生物量的迁移情况的研究已经展开。对这些矿区土壤的理化特性以及土壤和本地植物物种（条纹金雀花、岩蔷薇和粘毛旋覆花）中的总锑含量进行了测量。文中讨论了与远离采矿活动的对照区域的相应值进行的比较。通过测量水可提取部分来估算土壤中锑的迁移性；三个土壤区域的结果都很低，且无统计学差异。利用植物积累系数（PAC）来估算植物积累锑的能力。研究了季节（春季与秋季）对植物物种中锑含量的影响。来自玛丽·罗萨矿的条纹金雀花表现出锑排斥特性，而生长在圣安东尼奥矿的粘毛旋覆花标本则显示出显著的锑生物积累。
