Abstract
Predmet istraživanja ovog rada su tehnogena i smeđa tla u okolici TE Plomin (Istra) za koje se pretpostavlja da su onečišćena potencijalno toksičnim elementima te šljaka s otvorenog odlagališta koja predstavlja otpadni neizgoreni materijal iz termoelektrane. Glavni cilj rada je utvrditi i definirati mineraloške, geokemijske, morfološke i mikromorfološke značajke istraživanih tala te odrediti sadržaj određenih potencijalno toksičnih elemenata u tlu i interpretirati utjecaj termoelektrane na... More okoliš. Uzorkovanje je obavljeno 18.04.2013. godine na 4 lokacije u blizini TE Plomin. Utvrđen je ukupni sadržaj makro i mikro elemenata u tlu (ICP-ES i ICP-MS), provedena sekvencijska ekstrakcijska analiza (AAS i AES), te određen kapacitet kationske zamjene. Mineralni sastav određen je rendgenskom difrakcijskom analizom na prahu, dok je granulometrijski sastav uzoraka određen primjenom laserskog difraktometra. Mikroskopiranjem su utvrđeni mikrofacijesi stijena iz neposredne litološke podloge tla, definirane mikromorfološke karakteristike smeđeg tla te provedena determinacija ugljenih čestica. Smeđa tla bogatija su mineralima glina (ilitični materijal, kaolinit, klorit, vermikulit i mješanoslojni mineral glina) te imaju viši CEC od tehnogenih tala koja u odnosu na njih sadrže znatno veći udio ugljika i sumpora u deponiranim česticama ugljena (lignit odnosno lignit-subbituminozni ugljen). U šljaci su utvrđeni kristobalit, metakaolinit i mulit te čađa/koks. Primjenom mikromorfološke analize, čestice šljake utvrđene su i u smeđem tlu. Dokazano je da se iz čestica ugljene prašine u tlo izlužuju Hg, Sb, Se, Mo, U i Sr. Najkritičnije povišeni elementi su Ba, Cd, Cr, Mn, Ni, Se, Sr, V i Y. Elementi As, Cd, Cr, Se i U dominantno su antropogenog podrijetla i dokazuju negativan utjecaj termoelektrane. Elementi Mn, Sr, V i Y dijelom su antropogenog a djelom geogenog podrijetla, dok su Ba i Ni dominantno geogenog podrijetla. Less
Abstract (english)
Abstract: The purpose of this study is to investigate technogenic and cambic soils, probably contaminated with potentialy toxic elements and bottom coal ash from open disposal, which represents an unburned waste from TPP Plomin. Main objective of this survey is to define mineralogical, geochemical, morphological and micromorphological characteristics of studied soils, to determine the content of investigated potentialy toxic elements in soils and to interpret the impact of TPP on the... More environment. Sampling was carried out on April 18, 2013., at four sampling sites. in the area of TPP Plomin. Total content of macro and micro elements in soils was determined by ICP-ES and ICP-MS. Sequential extraction analysis as well as cation exchange capacity determination was conducted using AAS and AES. Mineral content was determined using powder XRD, while the granulometric analysis was performed using lasser diffractometer. Microfacies of underlying rocks, micromorphological determination of cambic soil and determination of coal particles in technogenic soils was determined by microscopic analysis. Cambic soils contain more clay minerals (illitic material, kaolinite, chlorite, vermiculite and mixed layer clay) and have higher CEC than technogenic soils, which contain much more C and S from deposited coal particles (lignite and lignite – sub bituminous coal). In bottom coal ash sample cristobalite, metakaoline and mullite, as well as coke coal and soot were determined. Micromorphological analysis revealed bottom coal ash particles in cambic soil. It is proved that Hg, Sb, Se, Mo, U and Sr are leached from bottom coal ash particles. The most critical concentrations are detected for Ba, Cd, Cr, Mn, Ni, Se, Sr, V and Y. Elements As, Cd, Cr, Se and U are dominantly of anthropogenic origin and they are an evidence of environmental impact of TPP Plomin. Elements Mn, Sr, V and Y are partially of anthropogenic, and partially of geogenic origin, while Ba and Ni are geogenic elements. Less
