The characteristics of rare earth elements in bulk precipitation, throughfall, foliage and lichens in the Lesní potok catchment and its vicinity, Czech Republic

<strong>ABSTRACT</strong> A comparison of rare earth elements' (REE) atmospheric signatures in various ecosystem compartments was carried out in the vicinity of the Lesní potok catchment (LP), Czech Republic. REE signatures were investigated from 2004 to 2006 in rainwater, throughfall, tree foliage (<em>Picea abies</em>, <em>Fagus sylvatica</em>) and lichens (<em>Hypogymnia physodes</em>) for selected elements (Al, Ca, Fe, K, Mg, Mn, Na, P, S, Si). REE concentrations increased in the following sequences: bulk precipitation &lt; beech throughfall &lt; spruce throughfall and spruce needles &lt; beech leaves ≪ lichens.

**摘要** 本研究针对捷克共和国莱斯尼波托克流域（LP）周边区域，对比了不同生态系统组分中稀土元素（rare earth elements, REE）的大气特征。研究于2004至2006年间，针对铝（Al）、钙（Ca）、铁（Fe）、钾（K）、镁（Mg）、锰（Mn）、钠（Na）、磷（P）、硫（S）、硅（Si）等选定元素，对雨水、穿透雨、树木叶片（欧洲云杉*Picea abies*、欧洲山毛榉*Fagus sylvatica*）以及地衣（柔扁枝衣*Hypogymnia physodes*）中的稀土元素特征展开了调查。结果显示，稀土元素浓度遵循如下序列：总沉降＜山毛榉穿透雨＜云杉穿透雨与云杉针叶＜山毛榉叶片≪地衣。
