Abstract

Prikupljena su 4 uzorka sedimenta na području KAS Sisak koji su likvefakcijom
izašli na površinu. Cilj analiza provedenih na njima je bio odrediti postoji li trag
antropogenog utjecaja u vidu onečišćenja, te ispitati može li se njihov sastav koristiti kao
referentna vrijednost u procjeni antropogenog opterećenja površinskih uzoraka sedimenta
rijeka. Napravljene su analiza veličine zrna, analiza geokemijskog sastava, udio karbonatne
komponente i analiza mineralnog sastava. Sva četiri uzorka su sličnih karakteristika po
pitanju geokemijskog i mineralnog sastava. Dobiveni rezultati i usporedba litoloških,
kemijskih i sedimentoloških karakteristika mjesta u blizini ustanovljeno je da u
analiziranom sedimentu nije detektirano antropogeno onečišćenje. Jedino su elementi
povezani sa aluvijem rijeka Save te Kupe i Odre u povećanim koncentracijama zbog
utjecaja rijeka. Naslage kojemu pripadaju uzorci su aluvij recentnih tokova (a). Dubina s
koje je mogao doći sediment procjenjuje se na 20 do 26 m ili vjerojatnije s 12 -15 m
dubine.

Abstract (english)

Four sediment samples were collected in the area of KAS Sisak, which came to
the surface through liquefaction. The goal of the analyses that were carried out on the
samples was to determine whether there is a trace of anthropogenic influence in the form
of pollution, and to examine whether their composition can be used as a reference value in
the assessment of the anthropogenic load of surface samples of river sediments. Analysis
of grain size, analysis of geochemical composition, proportion of carbonate component and
analysis of mineral composition were made. All four samples have similar characteristics
in terms of geochemical and mineral composition. The obtained results and a comparison
of the lithological, chemical, and sedimentological characteristics of the nearby places
revealed that no anthropogenic pollution was detected in the analysed sediment. The only
elements associated with the alluvium of the Sava and Kupa and Odra rivers are in
increased concentrations due to the influence of the rivers. The deposits to which the
samples belong are of the alluvium of recent flows (a). The depth from which the sediment
could have come is estimated at 20 to 26 m or more likely from 12-15 m deep.
