20.500.12556/DiRROS-7232 Fitoremediacija s kovinami onesnaženih tal z uporabo sadik dreves Phytoremediation of metal contaminated soil with the use of tree seedlings Na pehotnem strelišču vojaškega poligona Poček smo opravili poskus fitoremediacije na dveh raziskovalnih ploskvah. Prva ploskev leži na območju pehotnega strelišča in je onesnažena s Pb ter Cu, druga raziskovalna ploskev pa v njegovi okolici, kjer so tla manj obremenjena s kovinami. Zasadili smo juz izbranimi drevesnimi vrstami (Alnus glutinosa L., Acer pseudoplatanus L., Betula pendula Roth., Pinus sylvestris L., Salix caprea L.) po standardiziranem sistemu, izmerili rastne parametre ter določili vsebnosti kovin v koreninah, deblih in poganjkih sadik. Ugotovili smo, da kljub temu da izbrane drevesne vrste kopičijo v koreninah le Cd (BCF = 1,2), druge kovine pas prejemajo v manjših vsebnostih in vrstno specifično, lahko uporabimo večino preučevanih drevesnih vrst predvsem za fitostabilizacijo onesnaženih tal. Ugodno razmerje med bioakumulacijo in translokacijo kovin smo ugotovili za vse drevesne vrste z izjemo ive, kjer je prenos Cd v liste precejšen (TF = 6,9). Upoštevaje rastne parametre in privzem kovin v sadike je najprimernejša vrsta za remediacijo obravnavanega območja rdeči bor, najmanj pa iva. Phytoremediation was performed on two research plots at Poček military training ground. The first research plot (polluted with Pb and Cu) is situatedat the shooting range and the second in its close vicinity, where soil is less loaded with metals. Seedlings of five species (Alnus glutinosa L., Acer pseudoplatanus L., Betula pendula Roth., Pinus sylvestris L., Salix caprea L.) were planted on plots according to the standardised system; in addition, growth parameters and metal contents in roots, stems and shoots weremeasured as well. Although seedlings accumulate only Cd (BCF = 1.2) in their roots, and the rest of metals are taken up in smaller concentration and species specific, the majority of tree species have the potential for remediation and especially for phytostabilisation. Favourable ratio between bioaccumulation and translocation was determined for all species with the exception of Salix caprea, which was effective in taking up Cd in leaves (TF =6.9). The results of our study have shown that Pinus sylvestris is the most suitable species regarding growth parameters and metal uptake, whereas the least suitable is Salix caprea. fitoremediacija sadike dreves rastni parametri privzem kovin pehotno strelišče true false true Slovenski jezik Ni določen Znanstveno delo 2017-07-12 09:10:43 2017-07-12 09:10:43 2022-08-12 13:28:19 0000-00-00 00:00:00 2010 0 0 str. 67-86 Vol. 92 2010 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504.5 0351-3114 URN:NBN:SI:doc-POFRDHLE 1074134 6206978 zbgl-92-7.pdf zbgl-92-7.pdf 1 4698A704CC06B7F13C16256642B2AC20 366c956e18a5cd12c535bc15fbd1d5df336c82b2b9723b644672b9fc064a06e6 f26fb1b7-17b4-11ed-b6b8-001a4af901a5 20.500.12556/dirros/06ed7a9e-2ef1-4d59-a66b-fab5044dd798 https://dirros.openscience.si/Dokument.php?lang=slv&id=9077 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
