Lanthanides in Sicilian Soils

The whole soil dataset for Sicily comprises 2932 soil profiles, including 1773 soil augers and 907 mini-pits. Among these, here are extracted 117 soil profiles serve as benchmarks for Sicilian soil typological units (a total of 199 soil samples extracted and analyzed). The analyses involved drying, sieving, digestion with acids, and measurement of trace elements using ICP-MS, with validation against certified reference materials confirming accuracy and precision. Here are shown rare earth elements (REEs), i.e. lanthanides, yttrium, and scandium according to the International Union of Pure and Applied Chemistry (IUPAC) and are sometimes referred to, without Sc, as REY (lanthanides plus yttrium). REYs can be classified into two groups: light rare earth elements (LREYs) from 57La to 64Gd, and heavy rare earth elements (HREYs) from 65Tb to 71Lu, including yttrium (39Y).西西里岛全域土壤数据集共计包含2932个土壤剖面，其中涵盖1773个土壤钻探采样剖面与907个微型坑探采样剖面。本次研究从中选取117个土壤剖面作为西西里岛土壤类型单元的基准数据集，累计共提取并分析了199份土壤样品。分析流程包括样品干燥、过筛、酸消解，并采用电感耦合等离子体质谱法（Inductively Coupled Plasma Mass Spectrometry, ICP-MS）测定微量元素，通过标准参考物质开展验证，确保了分析结果的准确度与精密度。本次展示的稀土元素（rare earth elements, REEs）按照国际纯粹与应用化学联合会（International Union of Pure and Applied Chemistry, IUPAC）的定义，包含镧系元素、钇与钪；若不包含钪，则有时被称为REY（即镧系元素加钇）。稀土元素总类（REYs）可分为两类：轻稀土元素（light rare earth elements, LREYs）为原子序数57（镧La）至64（钆Gd）的元素，重稀土元素（heavy rare earth elements, HREYs）为原子序数65（铽Tb）至71（镥Lu）的元素，其中包含钇（39Y）。
