“…In this way, our method allowed correct evaluation of the influence of metal without other major disturbance. However, organic pollutants also accumulated by lichens (Bajpai et al, 2010;Harmens et al, 2013), were not investigated here. By applying the frequencies of studied species to these indices, and comparing to the enrichment factors from Agnan et al (2015), we observed that the four more polluted sites (i.e., HET 54a, EPC 08, CHS 35, and PM 72) as evidenced by bioindication, obtained negative scores (i.e., dominated by resistant lichen species), while several less contaminated sites (e.g., EPC 63 and EPC 74) obtained positive values (i.e., dominated by sensitive lichen species).…”

Ecological Indicators, Elsevier, 2017Elsevier, , 72, pp.99-110. <10.1016Elsevier, /j.ecolind.2016 b s t r a c tIn order to evaluate the metal resistance or sensitivity of lichen species and improve the bioindication scales, we studied lichens collected in eight plottings in French and Swiss remote forest areas. A total of 92 corticolous species was sampled, grouped in 54 lichen genera and an alga. Various ecological variables were calculated to characterize the environmental quality -including lichen diversity, lichen abundance, and Shannon index -, as well as lichen communities. Average ecological features were estimated for each study site and each of the following variables -light, temperature, continentality, humidity, substrate pH, and eutrophication -and they corresponded to lichen communities. Based on lichen frequencies, we calculated the index of atmospheric purity (IAP) and lichen diversity value (LDV). These two bioindication indices were closely related to lichen diversity and lichen abundance, respectively, due to their calculation formula. It appeared that LDV, which measures lichen abundance, was a better indicator of metal pollution than IAP. Coupling lichen diversity and metal bioaccumulation in a canonical correspondence analysis, we evaluated the resistance/sensitivity to atmospheric metal pollution for the 43 most frequent lichen species. After validation by eliminating possible influences of acid and nitrogen pollutions, we proposed a new scale to distinguish sensitive species (such as Physconia distorta, Pertusaria coccodes, and Ramalina farinacea) from resistant species (such as Lecanactis subabietina, Pertusaria leioplaca, and Pertusaria albescens) to metal pollution, adapted to such forested environment.

“…Because moss has no true roots, it takes up nutrients and pollutants primarily from the air and can accumulate them on or in its tissue. 48 Mosses are frequently used as biomonitors to evaluate airborne pollution from POPs. Moreover, the majority of studies have focused on the levels of polycyclic aromatic hydrocarbons (PAHs) in mosses, 49−51 and relatively few studies have been conducted on other POPs.…”

Mountains are observed to preferentially accumulate persistent organic pollutants (POPs) at higher altitude due to the cold condensation effect. Forest soils characterized by high organic carbon are important for terrestrial storage of POPs. To investigate the dominant factor controlling the altitudinal distribution of POPs in mountainous areas, we measured concentrations of polychlorinated biphenyls (PCBs) in different environmental matrices (soil, moss, and air) from nine elevations on the eastern slope of Mt. Gongga, the highest mountain in Sichuan Province on the Tibetan Plateau. The concentrations of 24 measured PCBs ranged from 41 to 510 pg/g dry weight (dw) (mean: 260 pg/g dw) in the O-horizon soil, 280 to 1200 pg/g dw (mean: 740 pg/g dw) in moss, and 33 to 60 pg/m 3 (mean: 47 pg/m 3 ) in air. Soil organic carbon was a key determinant explaining 75% of the variation in concentration along the altitudinal gradient. Across all of the sampling sites, the average contribution of the forest filter effect (FFE) was greater than that of the mountain cold trapping effect based on principal components analysis and multiple linear regression. Our results deviate from the thermodynamic theory involving cold condensation at high altitudes of mountain areas and highlight the importance of the FFE.

“…Leucodon sciuroides) was used in this research for method optimization. However, pleurocarpous mosess are very sensitive to pollution and dryness, and therefore are rare, sometimes absent, in urban areas and dry regions [13]. So, acrocarpous mosses, which grow on stone or brick walls and are more commonly used for studying urban environments and dry regions, were also analyzed.…”

“…The number of EMEP sites has been gradually increasing over the last few years however, spatial coverage is not sufficient yet. An alternative to conventional precipitation analysis is biomonitoring and mosses are among the organisms most frequently used for this purpose [13]. The moss technique is easier and cheaper than conventional precipitation analysis as it avoids the need for deploying large numbers of precipitation collectors with an associated long-term programme of routine sample collection and analysis.…”
