“…Indeed, even in these most remote areas, a manmade influence could be discriminate, through airborne particulate (Chiarenzelli et al, 2001). It should be noticed that Cd and Zn were associated, frequently found in the literature, explained by their physicochemical likenesses despite their distinct origin and biological affinity (Nimis et al, 2000;Brunialti and Frati, 2007;Gandois et al, 2010).…”

“…(HET54a < EPC08 < EPC63 < SP11 < EPC74). Each station contained five samples composed of a mixture of two foliose lichen species: Xanthoria parietina and Parmelia sulcata, species well known to accumulate trace elements (Garty, 2001 ;Nimis et al, 2000). Lichens thallus were collected at about 1.5 m high on several regional species tree trunks, with the aim to rise the representativness of the area.…”

“…Most of the studies used lichens to evaluate manmade contribution in local scale (Loppi et al, 2000;Rusu et al, 2006). However, very few studies have used lichens to evaluate the background levels relative to long-range atmospheric transport (Nimis et al, 2000;Brunialti and Frati, 2007). This study aimed to evaluate the geochemical background of atmospheric deposition of 16 trace elements using foliose lichens in remote areas in France.…”

Abstract. The human activities affect atmospheric compartment by trace elements emissions. The evaluation of atmospheric deposition can be performed by means of bioaccumulator organisms. In this study, we investigated two lichen species (Xanthoria parietina and Parmelia sulcata) from five remote areas far from local sources of contamination in France. PCA and enrichment factor were used to set up the geochemical background of 16 trace elements (including metals and metalloids). Some elements known to be influenced by anthropogenic activities, merge into the geochemical background, like As. The enrichment factors showed a high enrichment for Sb, Cd, Zn, As, Cu, and Pb, and to a less extent Sn and Mn. Others elements were associated to lithogenic contribution, including particularly As. A significant gradient from the South to the North-East was observed, convergently to the increased concentration registered in soils.

“…Hypogymnia physodes, Evernia prunastri, Ramalina farinacea. Distribution patterns of heavy metals can reveal hot spot areas and point sources [6][7][8]. Often metal distribution in epiphytic lichens can be explained by land use, such as urban and industrial areas, traffic and green areas etc.…”

Mosses, lichens and vascular plants may be used for monitoring airborne pollution, e.g. wet and dry deposition of metals in polluted areas. Best results are achieved when using transplantation methods including exposure for a certain period of time. Spreading of metals around point sources can be followed with great accuracy. Often at least semi quantitative estimates of deposition can be made. Biomonitoring methods are cheap and efficient but relations to results achieved by technical methods should be evaluated in more detail.

“…Interpretation is based on the naturality/alteration scale developed for element concentrations (Al, Ba, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V, and Zn) in foliose epiphytic lichens of Italy. This seven class scale (1: very high naturality, 2: high naturality, 3: middle naturality, 4: low naturality/alteration, 5: middle alteration, 6: high alteration, and 7: very high alteration) expresses the degrees of deviation (environmental alteration) from background conditions (naturality) based on the percentile distributions of element concentrations in lichens (Nimis et al 2000).…”

Lichens and mosses have extensively been used in multielemental large-scale biomonitoring studies of atmospheric metal pollution. Despite its high importance in the assessment of cumulative risk and the communication with risk managers, the presentation and interpretation of biomonitoring results have only been partially the center of interest for a standardized methodology and for the harmonization of the techniques. Here we attempt to expand and improve the up-to-date formal presentation of biomonitoring results, combining the Hasse diagram technique with GIS techniques. The implementation using real data has demonstrated that such an expansion and improvement, in the direction of cumulative risk assessment and management, is feasible and it is suggested for incorporation in biomonitoring studies. Biomonitors and BiomonitoringLichens and mosses may be considered as the most commonly used organisms in biomonitoring studies of metal pollution in the atmospheric environment (Kularatne and Freitas 2013;Ares et al. 2012).Lichens are by definition symbiotic organisms, usually composed of a fungal partner, the mycobiont, and one or more photosynthetic partners, the photobiont, which is most often either a green alga or cyanobacterium (Nash 2008), while mosses are photosynthetic non-vascular and non-woody plants grouped in the
