Analysis of Trace Element Concentrations of Some Lichens of Turkey
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
In this study, concentrations of six different elements (Ca, K, Fe,
Ba, Ti and Sr) were measured in twelve lichen species from two geographically
different regions (Northern Anatolia: Provinces of Trabzon,
Ordu, Artvin and Giresun and Eastern Anatolia: Erzurum province) in
Turkey. An annular 55Fe and 241Am radioactive source was used for excitation
of characteristic K X-rays using radioisotope excited energy
dispersive X-ray fluorescence method of multiple standard addition.
The incident beam and fluorescence X-rays emitted from the target were
detected and analyzed with an Ultra-LEGe detector. Five of the six
elements (Ca, K, Fe, Ba and Ti) are available in the twelve lichen species
living in 12 different habitats. But, Sr is the only available element in
some lichens living in some certain localities. Moreover, some lichens
living in some localities contain very high concentrations (almost 5-10
folds) of Ti and Ba (for example: Ordu-Ünye Çinarsuyu, Erzurum-Kösk
village for Ti, 0.384, 0.342 %, respectively and Trabzon-Maçka, Solma
plateau for Ba and 0.306 %).
