abstract = "The study of five forage grasses (Lolium multiflorum, Festuca rubra, Festuca arundinacea, Arrhenatherum elatius and Dactylis glomerata) was conducted on an uncontaminated cultivated land, of leached chernozem type, and on 'Nikola Tesla A' (TENT A) thermal power station ash deposit. The concentrations of: As, Pb, Cd, Zn, Ni, Fe and Cu in grasses grown on two media were compared. Grass samples have been collected in tillering stage, when they were in full development. The aboveground biomass was cut in three replications during the vegetative period at about 3-5 cm height, imitating mowing and grazing. The concentrations of As and Ni were elevated in media samples collected from TENT A ash deposit, while the level of all studied elements in soil samples collected from cultivated land were within allowed limits. The variance of certain elements amounts in plant material collected from TENT A ash deposit was less homogeneous; the concentrations of As, Fe and Ni were higher in grasses collected from ash deposit, but Pb and Cu concentrations were higher in grasses grown on cultivated land. The concentrations of Zn were approximately the same in plants collected from the sites, whereas Cd concentrations were slightly increased in grasses grown on the ash deposit. In general, it can be concluded from the results of this study that the concentrations of heavy metals in plants collected from both sites do not exceed maximal tolerant levels for fodder. The use of grasses grown on ash deposit for forage production should be taken with reserve., Pet krmnih trava, ježevica (Dactylis glomerata L.), francuski ljulj (Arrhenatherum elatius Presl.), italijanski ljulj (Lolium multiflorum Lam.), crveni vijuk (Festuca rubra L.) i visoki vijuk (Festuca arundinacea Schreb.) su ispitivane na nezagađenom njivskom zemljištu na oglednom dobru 'Radmilovac' u Beogradu, i na odlagalištu pepela termoelektrane 'Nikola Tesla A' (TENT A) u Obrenovcu. Merene su koncentracije As, Pb, Cd, Zn, Ni, Fe i Cu u zemljištu i pepelu, kao i u tkivima ispitivanih vrsta trava u cilju utvrđivanja zdravstvene bezbednosti u ishrani domaćih životinja. Uzorci trava su prikupljani u fazi klasanja, u punom vegetativnom razvoju. Skidana je nadzemna biomasa u 3 ponavljanja na visini od 3-5 cm, oponašajući ispašu ili kosidbu. Analiza je pokazala visok sadržaj As i Ni u pepelu dok je sadržaj svih elemenata u zemljištu bio u dozvoljenim koncentracijama. Koncentracije As, Cd, Fe i Ni su bile više u travama sa pepelišta, koncentracije Pb i Cu u travama sa njivskog zemljišta, dok su koncentracije Zn bile slične u uzorcima sa oba lokaliteta. Rezultati ispitivanja ukazuju da krma trava sa obe lokacije ne akumulira metale iznad tolerantnog nivoa za ishranu goveda, ali da se mora oprezno pristupiti mogućnosti korišćenja trava sa pepelišta za krmu.",
