Ocenjevanje kakovosti zraka na izbranih lokacijah v Mežiški dolini z uporabo epifitskih lišajev = Assessment of air quality at selected locations in the Meža valley using epiphytic lichensAl Sayegh-Petkovšek, Samar ; Sterže, Teja ; Poličnik, HelenaNa 12 izbranih lokacijah v Mežiški dolini smo spomladi leta 2022 opravili popis epifitskih lišajev z uporabo slovenske metode SI in nemške metode VDI. Z obema metodama se ocenjuje kakovost zraka na ... podlagi obstoječih rastnih tipov steljk in vrst epifitskih lišajev, na katere vplivajo predvsem plinasta onesnažila v zraku. Dodatno smo določali tudi indekse toksitolerance. Skupaj smo na prostostoječem drevju evidentirali 34 vrst epifitskih lišajev; 25 v Zgornji Mežiški dolini in 27 vrst epifitskih lišajev v Spodnji Mežiški dolini. Na podlagi izračuna povprečnega indeksa toksitolerance za posamezno lokacijo smo ugotovili, da na vseh lokacijah prevladujejo vrste, ki so manj občutljive za onesnaževanje. Največji indeks zračne čistosti, določen po metodi VDI, je bil izračunan za lokacijo Lom, sledita lokaciji Žerjav in Tolsti vrh, kjer smo evidentirali tudi največje število vrst lišajev. Stanje lišajske vegetacije na vseh obravnavanih lokacijah je primerljivo in kaže, da so lokacije srednje obremenjene s plinastimi onesnažili. V ospredje lahko postavimo lokaciji Dolgo Brdo in Preški vrh, kjer je izpostavljenost plinastim onesnažilom velika do zmerna; na lokaciji Dolgo Brdo pa je bila tudi obrast lišajev revna. Izračunani indeksi zračne čistosti so sicer pokazali, da je kakovost zraka v Zgornji Mežiški dolini nekoliko boljša kot v Spodnji Mežiški dolini, vendar razlike niso statistično značilne.Source: Acta Silvae et Ligni. - ISSN 2335-3112 ([Št.] 132, 2023, str. 13-28)Type of material - article, component partPublish date - 2023Language - slovenianCOBISS.SI-ID - 180300035
