Abstract

Cilj istraživanja ovog diplomskog rada bio je odrediti mineraloške i geokemijske
karakteristike tala industrijske zone istočnog dijela Grada Zagreba - Žitnjak u svrhu boljeg
razumijevanja distribucije mineralnih faza i elemenata na navedenom području. Uzorci tla,
su prikupljeni s 8 različitih lokacija od kojih je na jednoj načinjen vertikalni profil dubine do
80 cm. Na prikupljenim uzorcima izvršena su brojna laboratorijska istraživanja koja su
uključivala određivanje boje, vrijednosti pH i električne provodljivosti, udjela CaCO3,
selektivno otapanje karbonata, selektivno otapanje organske tvari, granulometrijsku analizu,
pripremu i obradu uzoraka pomoću ditionit citrat bikarbonata (DCB-a), sekvencijsku
ekstrakcijsku analizu (BCR), atomsku apsorpcijsku spektroskopiju (AAS), određivanje
kapaciteta kationske zamjene (CEC) i rendgensku difrakcijsku analiza (XRD). Utvrdilo se
da Cr, Ni i Cd prelaze MDK stoga predstavljaju potencijalnu opasnost za okoliš.

Abstract (english)

The main goal of the research in this thesis was to determine mineralogical and geochemical
characteristics of soil from the industrial zone in the eastern part of Zagreb– Žitnjak, in order
to better understand the distribution of mineral phases and elements in the specified area.
Soil samples were collected from 8 different locations, of which one is made of a vertical
profile of depth up to 80 cm. Numerous laboratory studies have been performed on the
samples collected, including determination of colour, pH value and electrical conductivity,
CaCO3 content, selective dissolution of carbonates, selective dissolution of organic matter,
granulometric analysis, preparation and processing of samples using dithionite citrate
bicarbonate (DCB), sequential extraction analysis (BCR), atomic absorption spectroscopy
(AAS), cation exchange capacity (CEC) and X-ray diffraction analysis (XRD). It was found
that Cr, Ni and Cd exceeded MDK and therefore represent potential environmental hazards.
