dc.description.abstract | Lignite and coal waste used as feed fuels in thermal power plants (TPPs) and semi-industrial fluidized bed boiler (FBB), as well as their representative fly ashes (FAs), were examined. Fly ashes were compared employing anions and cations content in correspondent water extracts, trace elements and polycyclic aromatic hydrocarbon concentrations, as well as health risk assessments of substances known to be of concern for public health. Fluoride and sulfate contents in water extracted FAs are far below the legislation limits for waste, classifying all investigated FAs as non-hazardous. Among investigated trace elements, Cd content is the lowest, while Mn content is the highest. The highest enrichment ratios are noticed for As, Pb, Hg, Cu, V and Cr. The results indicate that total PAHs content is elevated in FA from the combustion of coal waste (AFB), with fluoranthene prevailing. The cancer risk of As and the non- -cancer risk of As and Ni in some FAs surpass their respective permissible limits. The incremental lifetime cancer risk of an adult population indicates a potential PAHs risk in AFB, whereas all other fly ashes are within safe limits. | sr |
dc.description.abstract | U ovom radu, ispitivana su goriva (lignit i otpadni ugalj) koja se koriste u termoelektranama i poluindustrijskom postrojenju sa fluidizovanim slojem, kao i leteći pepeli dobijeni njihovim sagorevanjem. Leteći pepeli su upoređeni na osnovu: sadržaja anjona i katjona u njihovim vodenim ekstraktima, koncentracije elemenata u tragovima i policikličnih aromatičnih ugljovodonika (PAH), kao i procene zdravstvenog rizika koji potiče od prethodno pomenutih potencijalno opasnih supstanci. Sadržaj fluorida i sulfata u vodenim ekstraktima letećih pepela daleko je ispod zakonski dozvoljenih granica za otpad, na osnovu čega se mogu svrstati u bezopasne. Od ispitivanih elemenata u tragovima, sadržaj Cd je najniži, dok je koncentracija Mn najviša. Najveće obogaćenje pepela u odnosu na odgovarajući ugalj, primećeno je za As, Pb, Hg, Cu, V i Cr. Na osnovu dobijenih rezultata pokazano je da je ukupni sadržaj PAH najveći za leteći pepeo dobijen sagorevanjem otpadnog uglja. Među ispitivanim PAH, najvišu koncentraciju ima fluoranten. Rizici koji potiču od arsena (među kancerogenim elementima), kao i arsena i nikla (među nekancerogenim elementima), premašuju dozvoljene granične vrednosti. Vrednost procenjenog rizika od raka kod odrasle populacije u slučaju PAH, pokazuje da za leteći pepeo dobijen sagorevanjem otpadnog uglja postoji potencijalni rizik, dok su vrednosti za ostale pepele unutar dozvoljenih granica. | sr |
