The Sudetes are remarkable for the variety and number of peat bogs which receive nutrients via precipitation from atmospheric deposition as the only source of minerals. As this type of peat bogs with a very low buffering capacity is affected in the Sudetes by long-range exhausts from the former Black Triangle, strong response to atmospheric contamination may be expected. Therefore these peat bogs are highly suitable for bioindication purposes. As a result, metal levels in peat and plants should be controlled to evaluate potential ecological damage and to devise treatment strategies. The aim of this study was to evaluate the concentration of Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn in species from different plant functional types (PFTs): shrubs, evergreen dwarf shrubs, deciduous dwarf shrubs, tussock sedges, non-tussock sedges, forbs, Sphagnum mosses, brown mosses, liverworts, and algae collected from peat bogs of the Izera, Karkonosze, and Bystrzyckie Mountains. PFTs of the Karkonosze peat bogs situated above the upper forest line contained higher metal concentrations than those of the Izera and Bystrzyckie peat bogs from lower altitudes and surrounded by forests. Of all PFTs, the algae Zygogonium ericetorum accumulated the highest levels of Fe, Pb, and Zn. The PFTs of Sphagnum mosses were also very effective bioindicators of Cd, Cr, Fe, Hg, and Pb deposition to peat bog ecosystems. Pb, Fe, and Cr found in the examined vascular PFTs originated from atmospheric deposition. The results showed that airborne contaminants, including the ones connected with long-range transport, can make a significant contribution to a load of trace metals in peat bogs located above the upper forest line. These airborne depositions facilitate better recognition of the transport of contaminants carried over great distances and should be taken into account in monitoring and environmental protection programs. In particular, the results, first of all, show the differences in the bioaccumulation of metals in PFTs and their response to trace metal levels in such habitats. Of all PFTs, algae and Sphagnum mosses were the best choices for bioindication of trace metal pollution in ombrotrophic mountain mires. PFTs have not been used so far for investigating ombrotrophic mountain mires in Europe. Thus results of this investigation could be extended to this type of peat bogs in the mountains of Central Europe for better selection of PFTs for bioindication purposes.

苏台德人因泥炭沼泽的种类和数量而著称，它们通过大气沉降中的降水作为唯一矿物质来源获得养分。由于这种缓冲能力非常低的泥炭沼泽在 Sudetes 受到前黑三角的远距离废气的影响，预计对大气污染的强烈反应。因此，这些泥炭沼泽非常适合生物指示目的。因此，应控制泥炭和植物中的金属含量，以评估潜在的生态损害并制定处理策略。本研究的目的是评估来自不同植物功能类型 (PFT) 的物种中 Cd、Cr、Cu、Fe、Hg、Mn、Ni、Pb 和 Zn 的浓度：灌木、常绿矮灌木、落叶矮灌木、草丛莎草，非草丛莎草，杂草，从 Izera、Karkonosze 和 Bystrzyckie 山脉的泥炭沼泽中采集的泥炭藓、褐苔、地钱和藻类。位于上部林线以上的 Karkonosze 泥炭沼泽的 PFT 所含金属浓度高于来自低海拔并被森林包围的 Izera 和 Bystrzyckie 泥炭沼泽的金属浓度。在所有 PFT 中，藻类Zygogonium ericetorum积累了最高水平的铁、铅和锌。泥炭藓的 PFT 也是泥炭沼泽生态系统中 Cd、Cr、Fe、Hg 和 Pb 沉积的非常有效的生物指示剂。在检查的血管 PFT 中发现的 Pb、Fe 和 Cr 源自大气沉积。结果表明，空气中的污染物，包括那些与远距离运输有关的污染物，可以对位于上部森林线以上的泥炭沼泽中的微量金属负荷做出重大贡献。这些空气沉积物有助于更好地识别远距离携带的污染物的运输，应在监测和环境保护计划中加以考虑。特别是，结果首先显示了 PFT 中金属生物积累的差异及其对此类栖息地中痕量金属水平的反应。在所有 PFT 中，藻类和泥炭藓是生物指示营养型山地沼泽中痕量金属污染的最佳选择。迄今为止，PFT 尚未用于调查欧洲的营养性山地沼泽。因此，这项调查的结果可以扩展到中欧山区的这种泥炭沼泽，以便更好地选择用于生物指示目的的 PFT。
