Abstract

Predmet ovog diplomskog rada su uzorci tla prikupljeni na jugoistočnom dijelu Zagreba, na području Petruševca, u blizini željezničke pruge i rijeke Save. Cilj rada je određivanje geokemijskih i mineraloških karakteristika tla neobradive površine na području Petruševca, u svrhu određivanja mogućeg utjecaja željeznice te ostalih antropogenih izvora PTM-a na tlo. Određivanje koncentracija potencijalno toksičnih metala (As, Cd, Cu, Cr, Ni, Pb, Zn, Fe i Hg) provedeno je rendgenskom fluorescencijskom spektroskopijom (XRF analiza) te su izrađene karte stupnja onečišćenja zemljišta te prostorne distribucije analiziranih metala. Istraživano područje je s obzirom na stupanj onečišćenja zemljišta zagađeno kadmijem i živom te je velike onečišćenosti s obzirom na koncentracije kroma u tlu. Istraživano područje povećane je onečišćenosti s obzirom na koncentracije arsena, cinka, nikla i olova, a čisto je s obzirom na koncentracije bakra u tlu. Povišene koncentracije kadmija, žive, kroma, arsena, cinka, nikla i olova na istraživanom području mogu štetno utjecati na ljudsko zdravlje jer prelaze MDK vrijednosti. Osim toga, utvrđene su povišene koncentracije Cd, Hg, sporadično Cr te Ni. Povišene koncentracije Cd, Hg i Ni na istraživanom području antropogenog su podrijetla. Povišene koncentracije Pb i Zn su geogenog podrijetla inducirani antropogenom aktivnošću s izvorom u Sloveniji, uzvodno tokom rijeke Save kojom su valutice šljunka obogaćene s mineralima bogatima sfaleritom, galenitom i drugim mineralima mogle doći do istraživanog područja. Arsen je dominantno vezan uz Fe, te su povišene koncentracije ovog metala geogenog podrijetla. Nije utvrđena značajna korelacija između željezničke pruge kao glavnog antropogenog izvora onečišćenja i istraživanog tla. Ovim radom utvrđeni su drugi potencijalni antropogeni izvori onečišćenja s Cd, Hg i Ni.

Abstract (english)

The subject of this thesis is the soil samples collected in the southeastern part of Zagreb, in the area of Petruševac, near the railway line and the Sava River. The aim of the work is to determine the geochemical and mineralogical characteristics of the soil of the uncultivable surface in Petruševac, in order to determine the possible influence of the railway and other anthropogenic sources of PTM on the soil. Concentrations of potentially toxic metals (As, Cd, Cu, Cr, Ni, Pb, Zn, Fe and Hg) were determined by X-ray fluorescence spectroscopy (XRF analysis) and maps of the degree of soil pollution and spatial distribution of the analysed metals were made. Considering the degree of land pollution, the investigated area is polluted with cadmium and mercury, and it is highly polluted regarding the concentration of chromium in the soil. The investigated area is highly polluted regarding the concentrations of arsenic, zinc, nickel and lead, and is clean regarding the concentrations of copper in the soil. Elevated concentrations of cadmium, mercury, chromium, arsenic, zinc, nickel and lead in the research area can have a harmful effect on human health because they exceed the MAV values. In addition, elevated concentrations of Cd, Hg, sporadically Cr and Ni were found. Elevated concentrations of Cd, Hg and Ni in the investigated area are of anthropogenic origin. Elevated concentrations of Pb and Zn are of geogenic origin induced by anthropogenic activity with a source in Slovenia, upstream along the Sava River, which allowed gravel deposits enriched with minerals like sphalerite, galena and other minerals to reach the researched area. Arsenic is dominantly bound to Fe, and elevated concentrations of this metal are of geogenic origin. No significant correlation was found between the railroad as the main anthropogenic source of pollution and the investigated soil. This work determined other potential anthropogenic sources of pollution with Cd, Hg and Ni.
