Abstract

Predmet istraživanja ovog diplomskog rada su uzorci tla s područja vodocrpilišta Velika Gorica. Cilj rada bio je odrediti utjecaj poljoprivrednih sredstava na nesaturiranu zonu u području vodocrpilišta Velika Gorica, a time i na Zagrebački vodonosnik. Terenski rad uzorkovanja tla izvršen je na području vodocrpilišta Velika Gorica, blizu zračne luke Pleso. Laboratorijska analiza uzoraka tla je obavljena u Zavodu za mineralogiju, petrologiju i mineralne sirovine Rudarsko-geološko-naftnog fakulteta Sveučilišta u Zagrebu, u proljeće i ljeto 2016. godine. Utvrđeno je kako su koncentracije potencijalno toksičnih elemenata (Cu, Cd, Zn i Pb) te kationa i aniona (Na+, K+, NH4+, Mg2+, Ca2+, Cl-, NO3-, NO2- iSO42-) povišene u slojevima dubine do približno 80 cm. Do dubine od 110 cm vidljivo je sniženje koncentracija svih analiziranih elemenata. U pripovršinskim uzorcima tla, povišene koncentracije analiziranih parametara ukazuju na korištenje organskih gnojiva i pepela u svrhu obogaćivanja poljoprivrednog tla. Koncentracije analiziranih parametara smanjuju se do 110 cm dubine, pa ne postoji mogućnost zagađenja podzemne vode, koja se na istraživanom području nalazi na približno 750 cm dubine.

Abstract: The subject of this thesis is the research conducted on soil samples taken from the Velika Gorica water supply area. The aim of this research was to determine a possible agricultural influence on the unsaturated zone of the Velika Gorica water supply area, and also on the Zagreb water supply area. Fieldwork took place in the area near the Pleso airport. Sample analyses were carried out at the Department of Mineralogy, Petrology and Mineral Resources at the Faculty of Mining, Geology and Petroleum Engineering of the University of Zagreb during spring and summer of 2016. Increased concentrations of potentially toxic elements (Cu, Cd, Zn and Pb), cations and anions (Na+, K+, NH4+,Mg2+, Ca2+, Cl-, NO3-, NO2-and SO42-) were observed in sampled soil layers up to a depth of about 80cm. At depths between 80 and 110 cm, a decrease in concentrations of all elements was observed. Surface samples showed increased element concentrations, as well as the influence of agricultural usage of organic fertilizers and ashes. Considering that the approximate ground water depth is 750 cm and the concentrations of analyzed parameters decreased at depth of 110 cm, the possibility for pollution of ground water does not exist.
