Mining is an important source of metal pollution in the environment and abandoned mines are extremely restricted habitats for plants. Some plant species growing on metalliferous soils around mine tailings and spoil-heaps are metal-tolerant and accumulate high concentrations of metals. In this investigation, we aimed to perform a research in the CMC-abandoned copper mining area in Lefke-North Cyprus to assess the recent metal pollution in soil and plant systems. We collected 16 soil samples and 25 plant species from 8 localities around the vicinity of tailing ponds. Some concentrations of metals in soil samples varied from 185 to 1023 mg kg(-1) Cu, 15.2 to 59.2 mg kg(-1) Ni, 2.3 to 73.6 mg kg(-1) Cd and metals for plants ranged from 0.135 to 283 mg kg(-1) Cu, 0.26 to 31.2 mg kg(-1) Ni, 0.143 to 277 mg kg(-1) Cd. Atriplex semibaccata, Acacia cyanophylla, Erodium spp., Inula viscosa, Juncus sp., Oxalis pes-caprea, Pistacia lentiscus, Senecio vulgaris and Tragopogon sinuatus accumulated higher concentrations. BCF for Atriplex semibaccata was found very high, for this reason this plant can tentatively be considered as a hyperaccumulator of Cu and Cd, but it needs further investigation for its potential in phytoremediation.
采矿是环境中金属污染的一个重要来源，废弃矿山是植物生长极为受限的栖息地。一些生长在尾矿和废石堆周围含金属土壤上的植物物种具有耐金属性，并积累高浓度的金属。在本研究中，我们旨在对北塞浦路斯莱夫凯的CMC废弃铜矿地区进行研究，以评估土壤和植物系统中近期的金属污染情况。我们从尾矿池附近的8个地点采集了16个土壤样本和25种植物。土壤样本中某些金属的浓度范围为：铜185至1023毫克/千克、镍15.2至59.2毫克/千克、镉2.3至73.6毫克/千克，植物中的金属含量范围为：铜0.135至283毫克/千克、镍0.26至31.2毫克/千克、镉0.143至277毫克/千克。海滨滨藜、蓝叶金合欢、牻牛儿苗属植物、粘旋覆花、灯心草属植物、酢浆草、乳香黄连木、千里光和弯茎婆罗门参积累了较高浓度的金属。发现海滨滨藜的生物富集系数非常高，因此这种植物可初步被视为铜和镉的超富集植物，但需要对其植物修复潜力进行进一步研究。
