“…Bergamaschi et al (2007) (Nyarko et al, 2008) in recent years. AAS element analyses demonstrated that the content of toxic elements was higher in Ramalina pollinaria than in Evernia prunastri (Cansaran-Duman et al, 2011).…”

With fast economic development and industrialization, a vast range of genotoxic chemicals are produced and distributed into the environment. These chemicals adversely affect living organisms and often lead to serious diseases in human beings. Due to the highly conserved structure of the genetic material, it is possible to use a broad variety of species, including bacteria, yeasts, animals, and plants, in genotoxicity tests (Poli et al., 1999). In recent years, lichens have been used as good bioindicators of the genetic toxicity of environmental pollutants (Aras et al., 2010;Cansaran-Duman et al., 2011). Genotoxicity as a result of metal toxicity is also described to play a major role in DNA damage induction (Halliwell, 1990). Toxic chemicals induce several cellular stress responses and damage different cellular components such as membranes, proteins, and DNA (

-In this study we investigated the seasonal variations in the intracellular content of 14 trace elements (Al, As, Ba, Cd, Ce, Cr, Cu, Fe, Mn, Ni, Pb, Pd, Sb, Zn) and physiological parameters (namely chlorophyll a, chlorophyll b, ergosterol, photosynthetic efficiency, cell membrane integrity) in the thalli of the lichen Evernia prunastri (L.) Ach. exposed to an urban environment (Siena, central Italy). Lichen thalli were collected before each exposure period from an unpolluted area and transplanted to 16 sites; every 3 months the thalli were retrieved and replaced with new ones. Exposed-to-control ratios of trace elements revealed a marked intracellular accumulation of Cd in summer and autumn, and of Sb in autumn and spring, possibly as a result of vehicular traffic pollution. However, considering the low absolute concentrations of these elements, the intracellular fraction of depositions may hardly have caused an impairment of physiological parameters. As a matter of fact, indicators of photobiont vitality (content of chlorophylls a and b and photosynthetic efficiency) did not show any fluctuation across seasons, while changes in the indicators of mycobiont vitality (cell membrane damage and ergosterol content) overall did reflect some seasonal changes and/or lichen growth.

“…Increasing awareness of the potential hazards of large scale contamination of ecosystems by pollutants has highlighted the need for continuous monitoring of the levels of contaminants in the environment (4). The suitability of various lichen species in monitoring heavy metal air pollution has become of special interest to determine which species is the most suitable as a biomonitor of an environmental condition (20)(21) …”
