“…For instance, roadsides receive considerable amounts of traffic-generated pollutants, particularly lead (Sutherland and Tack 2000). Polluted sites in terrestrial and aquatic ecosystems have been monitored by using biological materials such as mosses (Rasmussen 1977;Yule and Lloyd 1984) and lichens (Seaward 1974;Seaward et al 1981). In addition to these biological materials, higher plants have been accepted as indicators for biomonitoring the heavy metal pollution in the environment (Aksoy and Öztürk 1997;Aksoy et al 1999;Samecka-Cymerman and Kempers 2001;Pugh et al 2002;Klump et al 2002;Piczak et al 2003;Swaileh et al 2004;Zeidler 2005).…”

In this study, we determined the heavy metal content (Cd(2+), Cr(3+), Cu(2+), Fe(3+), Ni(2+), Pb(2+), and Zn(2+)) in the soil surrounding the roots and different organs of Verbascum bombyciferum Boiss. (Scrophulariaceae), which is endemic to Uludağ Mountain, Bursa, Turkey. Plant samples were collected from roadsides, and heavy metal accumulation capabilities were tested. This is one of the pioneer species of ruderal plant communities on roadsides, building sites, rubbish dumps, etc. Different organs of plant samples (roots, stems, leaves, and flowers) and their soils were analyzed by inductively couple plasma optical emission spectroscopy for their heavy metal contents. Some of the analyzed heavy metals (Cd(2+), Cr(3+), Pb(2+), and Zn(2+)) were usually increased depending on the traffic in the sample sites, and this variation was also reflected in heavy metal content of plant samples. Our results show that this plant can be used as a bio-indicator species in the monitoring of increased Cd(2+), Cr(3+), Pb(2+), and Zn(2+) in the environment. We also concluded that V. bombyciferum have the capability of Cd(2+), Cr(3+), Cu(2+), Ni(2+), Pb(2+), and Zn(2+) accumulation.

“…Although many plants and among them especially lichens are known to accumulate and tolerate high concentrations of heavy metals [6], lichens are used in their normal habitat to monitor environmental air pollution in a simple and effective way since more than hundred years. Growth retardation or inhibition are clearly seen in places with high contaminations by sulphur dioxide or heavy metals [7].…”

Ca-Oxalate films and microbiological investigations of the influence of ancient pigments on the growth of lichens

Simultaneous thermogravimetry and thermomicroscopy were performed on Ca-oxalates which play an important role in the appearance of oxalate films connected with lichens superficially growing on human artefacts. Ca-oxalate exists in two well-described modifications: as the more stable monoclinic monohydrate whewellite and the less stable tetragonal dihydrate weddelite. Weddelite serves for lichens as a water absorbing and accumulating substrate which transforms to wheweUite when humidity drops. To follow these morphological changes optically and the water loss gravimetrically at the same time, a combination of thermomicroscopy and thermogravimetric analysis was constructed. The reflection light microscope was connected to a video camera and computer so that the morphological changes and the thermogravimetric curves could be shown simultaneously on the screen as function of time and temperature.Lichens -double organisms composed of algae and fungi -form surface layers not only on natural organic and inorganic material but also on human artefacts. In calcareous artefacts such as the famous Chinese terracotta soldiers or Egyptian epigraphs they lead to a destruction of the surface by forming Ca-oxalate layers and thus to a deterioration of the historian work of art. But in places where the surface is covered by some blue colours (Egyptian and Chinese Blue, Chinese Purple) the growth of lichens is inhibited and the artefacts are well preserved. The copper ion contained in the pigments is responsible for this effect since copper is a strong poison for microorganism.As lichens exhibit an extremely slow growth under natural and laboratory conditions the two lichen components: algae and fungi were investigated separately. The three mentioned ancient pigments have very low solubility products and thus do not act on the quickly growing fungi. But under special experimental conditions Egyptian Blue formed clear halos on the growth plates of the algae Chlorella minutissima and Trebouxia glomerata. These halos were compared with those of the easily soluble copper sulphate as a standard.

“…The hydrogen peroxide used was of the standard RP Norma type at 110 volumes for analysis (stabilized with 0.0005% of sodium stannate). Some authors (Garty and al., 1977;Goyal and Seaward 1981;Seaward and al., 1981) wash the thallus before mineralization, while others (Pilegaarde and al., 1979;Folkeson, 1981) mineralization directly on the harvested samples.…”

The use of bioindicator is very important for assessing the pollution intensity by accumulation of pollutants and lead in particular. The measurement of this accumulation in some organisms such as lichens and its effects on the physiological and morphological characteristics was found very effective to answer this problem. It is in this context that we have oriented our research whose objective is to determine the accumulating power of some lichenic species namely: Flavoparmelia sordians, Ramalina farinacea and Xanthoria parietina under the influence of three concentrations of lead nitrate: low, medium and high, respectively (0.207 gPb/l, 2.07 gPb/l and 20.7 gPb/l) in other parts highlight the impact of this accumulation on the Physiology (determination of chlorophyll) and morphology (morphological observation) of these species. The comparison between the three
