This study investigated selenium uptake and transport from the soil to 12 plant species in the mining area of Gumuskoy (Kutahya), Turkey. Plant samples and their associated soils were collected and analyzed for Se content by ICP-MS. Mean Se values in the soils, roots, and shoots of all plants were 0.9, 0.6, and 0.8 mg kg(-1), respectively. The mean enrichment coefficients for roots (ECR) and shoots (ECS) of these plants were 0.78 and 0.97. The mean translocation factors (TLF) were 1.33. These values indicate that all 12 plant species had the ability to transfer Se from the roots to the shoot, but that transfer was more efficient in plants with higher ECR and ECS. Therefore, these plants may be useful in phytoremediation in rehabilitating areas contaminated by Se because their ECR, ECS and TLFs are >1.
本研究调查了土耳其居穆什科伊(屈塔希亚)矿区土壤中硒向12种植物的吸收和转运情况。采集了植物样本及其相关土壤,并用电感耦合等离子体质谱仪(ICP-MS)分析了硒含量。所有植物土壤、根系和地上部分的平均硒含量分别为0.9、0.6和0.8 mg kg⁻¹。这些植物根系(ECR)和地上部分(ECS)的平均富集系数分别为0.78和0.97。平均转运系数(TLF)为1.33。这些数值表明,所有12种植物都有将硒从根部转运到地上部分的能力,但在ECR和ECS较高的植物中,这种转运效率更高。因此,这些植物的ECR、ECS和TLF均大于1,可能有助于对受硒污染地区进行植物修复。
