Flavoparmelia Caperata

Widely spread lichen specie Flavoparmelia caperata is used in a biomonitoring study for atmospheric trace metal pollution in natural ecosystems in Southeastern Serbia. The concentration and distribution pattern of 21 metals in lichens were determined by inductively coupled plasma atomic emission spectrometry. The difference observed between metal deposition in peripheral and central parts of lichen thalli reflected air quality changes in the last and previous years. These findings were confirmed with principal component analysis. Our study demonstrated the accumulation of Ba, K, Mg, Na, Tl and Zn in peripheral parts of thalli, while As, B, Cd, Cr, Cu, Fe, Ga, In, Li, Ni, Pb and Se were concentrated in central parts of thalli.

Three multi-elemental techniques (neutron activation analysis, proton-induced X-ray emission and inductively coupled plasma-atomic emission spectrometry) are described in terms of their special advantages in determining sulphur and heavy metal pollution in urban snow. Environmental analytical interpretations, including wash-out factors, enrichment factors, inter-elemental correlations, mobilization factors, and toxicity potential, are also discussed.

The Republic

In the framework of the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops under the auspices of the United Nations Economic Commission for Europe (UNECE-ICP Vegetation) Convention on Long-Range Transboundary Air Pollution (LRTAP), in 2002 and 2005, a moss biomonitoring technique was applied to air pollution studies in the Republic of Macedonia. The third moss survey took place in August and September 2010 when 72 samples of the terrestrial mosses Homalothecium lutescens and Hypnum cupressiforme were collected over the territory of the Republic of Macedonia, using the same sampling network grid as for the previous surveys. Using inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic absorption spectrometry (AAS), a total of 18 elements (Al, Ba, Ca, Cd, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Ni, P, Pb, Sr, V and Zn) were determined. To reveal hidden multivariate data structures and to identify and characterize different pollution sources, Principal Component Analysis was used. Distributional maps were prepared to point out the regions most affected by pollution and related to known sources of contamination. As in the previous surveys, the regions near the towns of Skopje, Veles, Tetovo, Radoviš and Kavadarci were found to be most affected by pollution, even though the median elemental content in the mosses in 2010 for  Cd, Cr, Cu, Ni, Pb and Zn was slightly lower than in the previous surveys. For the first time, P content in the moss samples was analyzed, and a higher content of this element as well as K in the mosses was observed in the agricultural regions of the country.

In order to establish a method for the simultaneous determination of trace elements Al, As, B, Ca, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Si, Ti, and Zn in Corydalis conspersa and Corydalis linarioides, we collected the samples from different areas and treated with acid hydrolysis into tissues to be detected by the way of inductively coupled plasma-atomic emission spectrometry compared with the standard element control method. We can know that the contents of Al, Ca, Fe, K, Mg, Na, and P in roots, stems, leaves, and flowers were higher. The contents of elements in different tissues and areas were as follows: flower > leaf > stem > root, Zeku County > Guide County > Nangqian County > Henan County. Among them, the contents of each element in the flowers of Maixiu Forest Farm were higher, while the contents of B, Cr, Cu, Li, Mn, Ni, Si, Ti, and Zn in roots, stems, and leaves of other areas were lower. The contents of heavy metal elements complied with the limit degree. A 3-factor model was obtained by principal component analysis which could clarify 82.46% of the total experimental data; the factors of Al, Fe, Mg, Na, P, Ca, Cu, Si, and Zn had great influence on the efficacy of 21 kinds of medicinal materials. Cluster analysis classified the samples into three categories; the flowers of Corydalis conspersa and stems of Corydalis linarioides from different collection areas are clustered containing high contents of type 1 and 3 characteristic components; the roots, stems, and leaves from other collection areas are clustered with low contents of 1 and 2 characteristic components. It can be used for the determination of trace elements in Corydalis conspersa and Corydalis linarioides to provide effective basis for revealing the function of trace elements with plant growth.
