Biologica Nyssana, 7 (1), September 2016: 19-29. The results of a study using epiphytic lichens as bioindicators, on teritory of three different urban areas in the Southern Serbia (Leskovac, Vlasotince, Lebane) are reported. The analysis of samples from 142 investigated points indicates presence of 53 lichens taxa. The aim of the study is to present the difference in air quality over a certain time interval. Using the Index of Atmospheric Purity- IAP values, it has been found that there are different air pollution zones: „normal“ zone, „struggle“ zone and „lichen desert“ zone. The comparison of the results obtained in 2002 and 2013 in Vlasotince indicates the presence of „normal“ zone in 2002 but, in 2013, the „normal zone“ area was completely replaced with the „struggle“ zone. In Leskovac, unlike the previous studies, a slightly narrowing “lichen desert" zone is noticed. In Lebane, there is a presence of all lichen zones.

Biologica Nyssana, 7 (1), Septembar 2016: 19- 29. Istraživanja kvaliteta vazduha korišćenjem lišaja kao bioindikatora sprovedena su na teritoriji tri različita urbana područja južne Srbije- Leskovac, Vlasotince i Lebane. Analiza uzoraka sa 142 istraživane tačke, ukazuje na prisustvo 53 lišajskih taksona. Cilj ovog istraživanja je da prikaže promene kvaliteta vazduha koje su nastale u određenom vremenskom periodu. Korišćenjem vrednosti indeksa atmosferske čistoće, konstantovano je prisustvo različitih zona zagađenja vazduha: „normalna“ zona, zona „borbe“ i zona „lišajske pustinje“. Poređenje rezultata dobijenih 2002. i 2013. godine u Vlasotincu, ukazuju na prisustvo „normalne“ zone u 2002. godini, međutim 2013. godine oblast „normalne“ zone je u potpunosti zamenjena zonom „borbe“. Na području Leskovca, razlika se ogleda u blagom suženju zone „lišajske pustinje“. U Lebanu je uočeno prisustvo sve tri zone lišajske indikacije.

Air quality lichen monitoring at three… Introduction Material and methods Sample location The air quality is getting worse all over the world. The strongest effects are felt in urban areas. Air The Southern Serbia includes Jablanica district. The pollution continuously increases, suggesting the need administrative centre of the district is the town of for timely detection, quantification and determination Leskovac, the biggest settlement in the Southern of levels of atmospheric pollution and introduction of Serbia. This is the town with around 65289 monitoring system. Biological monitoring is based inhabitants. The mean annual temperature is 10.7 °C on the assumption that changes in the environment and the mean annual rainfall is 591.6 mm. The most affect the indicator organisms and these changes can frequent winds are north, northwest and south be effectively used as an early warning signal for (Republic Hydrometeorological Service of Serbia). detecting of environmental changes (G a r t y , 2001). Leskovac has got a developed textile, chemical and Lichens are used in the biomonitoring studies pharmaceutical industry. because they are one of the most sensitive and The town of Vlasotince is located in the valuable biomonitors of atmospheric pollution southeastern part of Serbia, in the area of middle and (Sujetoviene , 2015). bottom basin of the river Vlasina. The town has a Lichens are symbiotic organisms composed of population of 15882 people. The mean annual a fungus and an alga, usually either a cyanobacterium temperature is 11.8 °C and the mean annual rainfall or green algae. It is estimated that there are is 724.3 mm, which is much higher than in the approximately 25000 species of lichens surrounding towns. East – west is the most common (C h a p m a n , 2009). These unique organisms have a direction of movement of the winds (Republic number of specific properties and therefore can be Hydrometeorological Service of Serbia). used for different purposes. Changes in epiphytic lichen diversity are used as indicators of environmental conditions and have been widely applied in air quality assessments and monitoring programs around the world (L l o p et al., 2012). They are very good indicators of air quality. In the last decade of the twentieth century, a more intense use of epiphytic lichens as bioindicators on the territory of the Republic of Serbia began (M i l i ć , 1980; S a v i ć , 1991; 1997; 1998; Stamenković , 1992; M i l i ć & B l a ž e n č i ć , 1993; T o d o r o v i ć , 1995; C v i j a n et al., 1995; 1997; 2008; Stamenković , 1995; 1996; 1997; 1998; 2002; C v i j a n & Stamenković , 1996a; 1996b; S t a n k o v i ć et al., 1999; P e j č i n o v i ć , 2000; Stamenković & C v i j a n , 2002; 2003; 2004; 2010; Stamenković et al., 2010; 2012; Stamenković et al., 2013a; 2013b; J e v t i ć , 2013; N o v k o v i ć , 2013).
