“…This technique seems to be particularly useful in air monitoring. So far the vast majority of measurements of metal concentration in the atmosphere have been carried out using lichens and mosses [3][4][5][6][7][8][9][10][11][12][13][14]. However, in polluted areas higher plants seem to be more suitable as ecological indicators of air contamination, since lichens and mosses are often missing from such environments [15][16].…”

We analyzed concentrations of Cd, Cu, Fe, Pb, and Zn in bark, leaves, young shoots, pericarp, and seeds of Robinia pseudoacacia from several sites (three industrial cities and two rural villages) in southern Poland. The objective of the study was to determine the possible usefulness of various organs and tissues of this species for biomonitoring. The analyses showed that bark and leaves are organs that may serve as good bioindicators. The lowest concentrations of Cd, Pb, and Zn were found in one of the industrial cities in the area. On the other hand, the concentrations of Cd, Pb, and Zn were similar in the rural areas when compared to the concentrations observed in the cities. The high level of metal contamination of air in rural areas may be a result of the long-range transport of emissions. Also, the use of bark and leaves of R. pseudoacacia enables us to estimate the level of contamination by Fe and Cu of areas in the vicinity of railway tracks. On the basis of the data presented in this paper and the data from references, a conclusion can be drawn that the bark and leaves of R. pseudoacacia are good bioindicators of metal contamination of air in towns and

“…Sections were mounted self-supported onto sticky carbon tabs, glued to an Al-holder, and classified from young (peripheral), the outermost 3-4 mm of the thallus, the lobes distinguishable by their colour and their lack of rhizinae, equivalent to an age of about 1 year, to older (central), more central part of the thallus [3]. The samples were examined at the proton microprobe set up of Instituto Tecnológico e Nuclear of Sacavém [21].…”

“…However, these interpretations do not explain the relatively short time-scale changes in lichen mineral composition in a fast response to changes in ambient elemental availability [3,18]. In addition to particle entrapment, lichens can acquire substances from the environment by extra-or intra-cellular uptake of ions in solution.…”

“…The patterned accumulation and zoning of metal concentrations in lichen thalli is an actual issue associated with the use of lichens as biomonitors. Element-specific partitioning between old and younger parts of foliose lichen thallus is reported and suggested as influencing the biomonitoring results [1][2][3][4]. It was also hypothesized that differences in the lichen thallus constitution (algae, fungi) may cause the different patterns of element distribution in peripheral and central lichen parts [3].…”

Micro-scale elemental distribution in the thallus of Flavoparmelia caperata transplanted to polluted site

The elemental microdistributions of peripheral and central parts of the lichen Flavoparmelia caperata exposed to industrial pollution were analysed, in order to better understand the elements distribution patterns in relation to the lichen constitution, thereby increasing our knowledge on uptake and release mechanisms. Nuclear microscopy techniques were used to visualize elemental distributions in sample transepts and associate their concentrations to sample morphology. The distribution data of the elements studied suggests there is biological regulation of internal concentrations. Considering thallus parts, element-specific internal translocation should be taken into account as one more factor affecting lichen ''memory length''.
