摘要 这篇论文的目的是验证地衣是否有能力积累与火山活动有关的大气污染物。1994年和1995年，在意大利的两个活跃的火山区--埃特纳火山和瓦尔卡诺岛--采集了大约100个地衣。使用仪器中子活化分析和电感耦合等离子体质谱对每个地衣的27种元素进行了分析。地衣成分反映了火山颗粒物质的贡献，根据一些亲岩石元素的浓度可以区分两个研究区。此外，地衣中的元素(As、Sb、Br、Pb)--来自气体排放(羽流、富马烯)--在山上也显示出不同的地球化学趋势。埃特纳和瓦卡诺。
Abstract The aim of this paper is to verify whether lichens have the capacity to accumulate atmospheric contaminators linked to volcanic activity. About 100 lichens were collected in 1994 and 1995 from two active volcanic areas in Italy: Mount Etna and Vulcano Island. Twenty-seven elements were analyzed for each individual lichen using Instrumental Neutronic Activation Analysis and Inductively Coupled Plasma-Mass Spectrometry. Lichen composition reflects the contribution of the volcanic particulate material, and the two areas investigated can be distinguished on the basis of the concentration of some lithophile elements. Moreover, the distribution in lichens of the elements (As, Sb, Br, Pb) – derived from gas emissions (plume, fumaroles) – also shows different geochemical trends on Mt. Etna and Vulcano.
