Fourteen rare earth elements were determined in mosses (Pleurozium schreberi) and soils (subhorizon-Ofh and -Ol, mixed horizon-AE and AEB) from south-central Poland. The results were normalized against North American Shale Composite (NASC) and Post-Archean Australian Shales (PAAS). The distribution of REEs in the moss-soil system differed considerably, but all the samples showed the average percent of increase of medium rare earth elements. The shale-normalized concentration ratios calculated for selected elements (LaN/YbN, GdN/YbN, LaN/SmN) were in the range of 1.22-2.43, 1.74-3.10 and 0.86-1.09. Both subhorizon-Ofh (-Ol) and horizon-AE (-AEB) showed a weak enrichment of Gd. The shale-normalized patterns of soils showed a somewhat negative Eu anomaly in the horizon-AE (-AEB), and a slightly negative Ce anomaly in the subhorizon-Ofh (-Ol). A strongly positive Eu anomaly and a somewhat negative Nd anomaly were found in the moss samples.
从波兰中南部采集了苔藓（Pleurozium schreberi）和土壤（下土层-Ofh 和 -Ol、混合土层-AE 和 AEB）样本，共 14 种稀土元素在其中被检测到。这些结果是与北美页岩组合（NASC）和后太古澳大利亚页岩（PAAS）相比较得出的。在苔藓-土壤系统中，REE 的分布差异很大，但所有样本都显示出中等稀土元素的平均百分增长率。对于选定元素（LaN/YbN、GdN/YbN、LaN/SmN）计算的页岩标准化浓度比在 1.22-2.43、1.74-3.10 和 0.86-1.09 之间。下土层-Ofh（-Ol）和土层-AE（-AEB）都显示出对 Gd 的微弱富集。土壤的页岩标准化模式在土层-AE（-AEB）中显示出略微的负 Eu 异常，在下土层-Ofh（-Ol）中显示出略微的负 Ce 异常。苔藓样本中发现了强烈的正 Eu 异常和略微的负 Nd 异常。
