In this investigation we focus on the evaluation of changes in metal pollution between 1986 until 2011 by Sphagnum species as bioindicators in 100 km part of the Sudety mountains influenced by the former Black Triangle Region. Concentrations of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in various Sphagnum species all from ombrotrophic bogs in the Sudety mountains (SW Poland). The tested hypothesis was that overall improvements in pollution control in the former Black Triangle Region between 1986 until recent reduced the amount of metals deposited and accumulated by these plants. Concentrations of Cd, Cr, Cu, Fe, Pb and Zn in Sphagnum species were very high in 1986 indicating a heavy pollution of the examined bogs in this period, and significantly higher than in samples collected in 2011. The PCCA ordination showed the similar pattern in all bogs. In 2011 concentration of the Co was significantly higher in hollow species and concentration of Mn was significantly higher in those from hummocks. Differences between hollow/hummock sites were more important than species-specific abilities of Sphagnum mosses to accumulate metals. Species from hollows were better bioindicators of Co and those from hummocks were better bioindicators of Mn pollution.
在这项研究中，我们专注于评价 1986 年至 2011 年期间，丝氨酸物种作为生物指示剂在受前黑三角地区影响的苏台德山脉 100 公里范围内金属污染变化情况。在苏台德山脉（波兰西南部）的各种泥炭藓中测量了 Cd、Co、Cr、Cu、Fe、Mn、Ni、Pb 和 Zn 的浓度，所有这些泥炭藓均来自于高位沼泽地。测试的假设是，1986 年至最近期间，前黑三角地区污染控制的整体改善减少了这些植物沉积和积累的金属量。1986 年，丝氨酸物种中的 Cd、Cr、Cu、Fe、Pb 和 Zn 浓度非常高，表明这一时期检查的沼泽地受到了严重污染，明显高于 2011 年采集的样本。PCCA 排序在所有沼泽地都显示出相似的模式。2011 年，空心物种中的 Co 浓度显著升高，而凸起物种中的 Mn 浓度显著升高。空心/凸起地点之间的差异比泥炭藓物种积累金属的特定能力更为重要。空心物种是 Co 的更好生物指示剂，凸起物种是 Mn 污染的更好生物指示剂。
