In this study, the relationship between heavy metals (HMs) concentrations in soils and several weeds including Cyclosorus parasiticus, Dicranopteris linearis, Pityrogramma calomelanos, and Pteris vittata in three mining sites (Cam Gia (Thai Nguyen city), Tan Long (Dong Hy district), and Ha Thuong (Dai Tu district)) in Thai Nguyen province, Vietnam, have been investigated. The levels of HMs varied among soil origins and showed the contaminations of As, Cu, and Pb in soil samples collected in Dong Hy and Dai Tu districts. In addition, the HM distribution and cocontamination phenomena in different soils significantly affected the HM residues and transportation abilities into different species as well as tissues. Moreover, based on the analysis of bioaccumulation factor (BF) and translocation factor (TF), C. parasiticus and D. linearis were found potentially for phytoextraction by roots, while P. calomelanos and P. vittata were suitable for hyperaccumulation in shoots and leaves. Consequently, the strongest antioxidant property by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide anion (SRSA) radical scavenging assays were demonstrated in the methanol root extracts of C. parasiticus and P. vittata, respectively. In conclusion, the correlation among HM in soils and tissues with antioxidant property allows us to hypothesize that the presence of these elements can enhance the antioxidant activity of plant extracts, suggesting to apply the weeds in phytoremediation as well as in phytomedicine.

越南太原省采矿活动下土壤和杂草中重金属的相互作用及其抗氧化能力

在这项研究中,土壤中重金属 (HMs) 浓度与包括 Cyclosorus parasiticus、Dicranopteris linearis、Pityrogramma calomelanos 和 Pteris vittata 在内的三个矿区(Cam Gia(泰国阮市)、Tan Long(Dong Hy 区))中的几种杂草之间的关系) 和 Ha Thuong (Dai Tu 区)) 位于越南太原省。HMs 的水平因土壤来源而异,显示在东海和戴土地区采集的土壤样品中的 As、Cu 和 Pb 污染。此外,不同土壤中 HM 的分布和共污染现象显着影响 HM 残留和向不同物种和组织的运输能力。此外,基于生物蓄积因子(BF)和易位因子(TF)的分析,C. parasiticus 和 D. 发现有潜在的通过根提取植物的线材,而 P. calomelanos 和 P. vittata 适合在芽和叶中超积累。因此,1,1-二苯基-2-苦基肼 (DPPH) 和超氧阴离子 (SRSA) 自由基清除试验分别在 C. parasiticus 和 P. vittata 的甲醇根提取物中证明了最强的抗氧化性能。总之,土壤和组织中的 HM 与抗氧化特性之间的相关性使我们可以假设这些元素的存在可以增强植物提取物的抗氧化活性,建议将杂草应用于植物修复和植物医学。1,1-二苯基-2-苦基肼 (DPPH) 和超氧阴离子 (SRSA) 自由基清除试验分别在 C. parasiticus 和 P. vittata 的甲醇根提取物中证明了最强的抗氧化性能。总之,土壤和组织中的 HM 与抗氧化特性之间的相关性使我们可以假设这些元素的存在可以增强植物提取物的抗氧化活性,建议将杂草应用于植物修复和植物医学。1,1-二苯基-2-苦基肼 (DPPH) 和超氧阴离子 (SRSA) 自由基清除试验分别在 C. parasiticus 和 P. vittata 的甲醇根提取物中证明了最强的抗氧化性能。总之,土壤和组织中的 HM 与抗氧化特性之间的相关性使我们可以假设这些元素的存在可以增强植物提取物的抗氧化活性,建议将杂草应用于植物修复和植物医学。
