The current study aims to perform a field survey of three abandoned mining sites in the southern centre of Morocco to assess the recent metal pollution in soils and accumulation potential of plant species. Native plants and soils were sampled at several sites in the studied mines and analysed for Cu, Zn, Pb and Cd concentrations. Soils in the investigated sites proved to be deficient in major macronutrients and to contain toxic levels of Cu, Zn, Pb and Cd. Botanical survey of the prospected sites showed the abundance of diverse plant communities (46 species and 19 families), with no obvious toxicity symptoms. Results showed that the concentrations of heavy metals were different in the same plant species and from plant species to another. Eight plants of 46 species namely Hirschfeldia incana (L.) Lagr.-Foss, Citrullus vulgaris (L.) Schradi, Portulaca oleracea L., Stipa capensis Thunb., Lactuca viminea (L.) J.Presl & C.Presl, Forsskaolea tenacissima L., Lycium intricatum Boiss. and Hammada scoparia (Pomel) Iljin were considered as the best-performing specimens due to their high ability to accumulate multiple metals in their shoots and roots without being affected by excessive metal contents. This was confirmed by the transfer factors generally higher than 1. Consequently, these tolerant and native plant species could be used as tools for an effective phytorestoration of metal-contaminated sites.

当前的研究旨在对摩洛哥南部中部的三个废弃矿区进行实地调查，以评估近期土壤中的金属污染和植物物种的积累潜力。在所研究的矿山中的多个地点对本地植物和土壤进行了采样，并分析了其中的Cu，Zn，Pb和Cd浓度。被调查地点的土壤被证明缺乏主要的常量营养素，并且含有铜，锌，铅和镉的有毒水平。对潜在地点的植物学调查显示，该地区有丰富的植物群落（46个物种和19个科），没有明显的毒性症状。结果表明，同一植物物种和另一植物物种中的重金属浓度是不同的。八种植物共46种，分别是Hirschfeldia incana（L.）Lagr.-Foss，寻常西瓜（L.）Schradi，马齿苋属，针茅兔藤。，莴苣枥（L.）J.Presl＆C.Presl，Forsskaolea藤L.，枸杞intricatum羌活。和Hammada scoparia（Pomel）Iljin被认为是表现最好的标本，因为它们能够在芽和根中积累多种金属而不受过多金属含量的影响。转移因子通常高于1证实了这一点。因此，这些耐性和天然植物物种可以用作有效地对金属污染部位进行植物诱捕的工具。
