摘要

第聂伯罗市是乌克兰著名的工业中心，其工业发展尤为突出。本研究的重点是附近的两种常见植物物种：Ambrosia artemisiifolia L. 和 Erigeron canadensis L.。采样点距离第聂伯罗市与电池生产和回收工厂相关的排放源 12.02 公里。使用原子发射光谱法分析了土壤中的重金属浓度，例如铬、铜、铅和锌，以及刺五加（Ambrosia artemisiifolia L.）和麦冬（Erigeron canadensis L.）的植物组织。结果表明，铜和锌在受检植物中的生物蓄积性最高，而铅的生物蓄积性最低。两种植物吸收金属的顺序为：铜 > 锌 > 铬 > 铅。与土壤相比（Ftheor < Fexp，p < 0.05），在这两种研究植物中观察到的金属浓度明显更高，这表明金属对这些植物具有生物利用率。易位系数（TF）表示芽/根中金属浓度的比率。Erigeron canadensis L. 四种金属的 TF 值都超过了 1。另一方面，Ambrosia artemisiifolia L. 对铬、铜和锌的 TF 值超过了 1。因此，这两个物种都是受这些研究金属污染的土壤的潜在植物修复剂。

Bioaccumulation of Cr, Zn, Pb and Cu in Ambrosia artemisiifolia L. and Erigeron canadensis L.

The city of Dnipro, a prominent industrial hub in Ukraine, is recognized for its particularly its significant industrial development. This study focused on two prevalent plant species, Ambrosia artemisiifolia L. and Erigeron canadensis L., within the vicinity. Sampling was conducted at points located 12.02 km away from the emission sources associated with battery production and recycling plants in Dnipro. Analysis of heavy metal concentrations such as, Cr, Cu, Pb, and Zn was conducted using atomic emission spectrometry from the soil and plants tissues of Ambrosia artemisiifolia L. and Erigeron canadensis L. The translocation coefficient (TF) was calculated for both plant species. The results revealed that Cu and Zn exhibited the highest bioaccumulation in the examined plants, whereas Pb demonstrated the lowest. The order of metal uptake by both plants was determined as Cu > Zn > Cr > Pb. Significantly higher concentrations of these metals were observed in the two studied plants compared to the soil (Ftheor < Fexp, p < 0.05), suggesting the bioavailability of metals for these plants. The translocation coefficient (TF) represented the ratio of metal concentration in the shoot/the root. The TF value of Erigeron canadensis L. exceeded 1 for four metals. On the other hand, the TF value of Ambrosia artemisiifolia L. surpassed 1 for Cr, Cu, and Zn. Consequently, both species emerge as potential phytoremediators for soils contaminated with these studied metals.

期刊介绍： Resources (ISSN 2079-9276) is an international, scholarly open access journal on the topic of natural resources. It publishes reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and methodical details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: manuscripts regarding research proposals and research ideas will be particularly welcomed, electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Subject Areas: natural resources, water resources, mineral resources, energy resources, land resources, plant and animal resources, genetic resources, ecology resources, resource management and policy, resources conservation and recycling.
