Abstract

U sklopu europskog projekta "Urban Geochemistry in Europe (URGE)–Soil, Childern, Health", čiji je
cilj geokemijsko kartiranje određenih europskih gradova pomoću jedinstvenih metoda te izrada geokemijske
karte urbanog tla za različite kemijske elemente, kao grad predstavnik Republike Hrvatske odabran je grad Sisak.
U širem centru grada odabrana su dva pedološka profila (profili PR1 i PR2) na kojima su provedena terenska i
laboratorijska istraživanja. Ukupno je analizirano jedanaest uzoraka (šest iz profila PR1 i pet iz profila PR2). Oba
profila su razvijena na tehnogenom tlu, deposolu. Utvrđeno je da su tla predstavljena profilom PR1 (cijeli profil) i
profilom PR2 (gornji dio profila) bila pod značajnim antropogenim utjecajem (povišen ukupni sadržaj Cu, Zn,
Ag, Au, Hg, Sn i Pb). Sekvencijskom ekstrakcijskom analizom prema BCR proceduri, određeni su udjeli Pb, Zn,
Cd, Cu, Cr i Ni u četiri frakcije: (1) karbonatnoj, (2) frakciji Fe-Mn oksida i hidroksida, (3) organsko-sulfidnoj
(reduktivnoj) te (4) rezidualnoj frakciji. Analiza ekstraktanata je izvršena primjenom atomske absorpcijske
spektrometrije (AAS). Dobiveni podaci uspoređeni su s vrijednostima u relevantnim pravilnicima o onečišćenju
tla. Utvrđeno je da je PR1onečišćeniji (Cu, Pb i dijelom Zn) od PR2 (po jedan uzorak onečišćen je s Zn i Ni).
Onečišćenje profila PR1 može biti posljedica ostataka rimskih predmeta koji se nalaze u tlu (u blizini profila
nalaze se arheološke iskopine) odnosno, industrijskih postrojenja koja se nalaze u samom gradu Sisku i u
njegovoj okolici. Izvor onečišćenja uzorka profila PR2 nije moguće točno utvrditi. Ovo istraživanje pokazalo je
da bi bilo nužno izraditi pravilnik koji će se temeljiti na upotrebi zemljišta kako bi se moglo pravovaljano
ocijeniti stupanj onečišćenja.

Abstract: The goal of the European project "Urban Geochemistry in Europe (URGE) – Soil, Childern, Health" is a
geochemical mapping of specific European cities using an unique method and production of an urban soil
geochemical maps for different chemical elements. As the part of the project, city Sisak was chosen to be main
representative of Republic of Croatia. Field and laboratory research were conducted on the two pedologic profiles
chosen in the center of Sisak (PR1 and PR2). Overall, the research was made on eleven samples, six from profile
PR1 and five from profile PR2. Both profiles were developed on the tehnogenic soil - deposol. It was established
that the soil represented in PR1 (the whole profile) and in PR2 (only upper part of profile) were under significant
anthropogenical influence (higer composition of Cu, Zn, Ag, Au, Hg, Sn and Pb). The sequential-extraction
scheme recommended by BCR was used and Pb, Zn, Cd, Cu, Cr and Ni were determined in four fractions: 1)
carbonate fraction, 2) Fe-Mn oxides and hydroxides fraction, 3) organic-sulphide fraction and 4) residual
fraction. The analysis was performed by using an atomic absorption spectrophotometer (AAS). The final results
were compared with the relevant rulebook values of the soil contamination. It was determined that PR1 is more
contaminated (Cu, Pb and partially Zn) than PR2 (one sample is polluted by Zn and Ni). Contamination of profile
PR1 could be a consequence of the Roman remains found in the soil (there are archeological excavation next to
the profile) and industrial plants that were placed in the center of Sisak and its vicinty. Source of contamination
of the sample in profile PR2 can not be accurately determined. This research proved that it would be necessary
and vital to do the rulebook based on the level of soil use to determine the level of contamination.
