Abstract

Predmet istraživanja ovog diplomskog rada je profil aluvijalnog (fluvijalnog) tla na lokaciji Hlebine-Dedanovice u Podravini. Osnovni cilj istraživanja bio je izraditi sorpcijske izoterme potencijalno toksičnih metala (bakar, cink, kadmij) kroz profil tla u svrhu određivanja sorpcijskog kapaciteta tla te utjecaja na podzemnu vodu istraživanog područja. Kako bi se dobio uvid u procese ponašanja potencijalno toksičnih metala kroz istraživani profil tla napravljene su sljedeće laboratorijske analize: organska tvar, mineraloški sastav na frakciji manjoj od 2 mm, kapacitet kationske zamjene (CEC), te željezni i manganski oksidi. Bakar je pokazao da ima najveću sorpciju u tlu, sorpcijski kapaciteti (RSC) su vrlo visoki u svim slojevima (iznad 96,8 %), pa u slučaju onečišćenja neće doći do njegovog značajnijeg pronosa prema podzemnoj vodi. Cink ima manje sorpcijske vrijednosti od bakra (najmanji RSC iznosi 85,1 %), ali veće od kadmija koji je pokazao suprotno ponašanje u tlu s najmanjim sorpcijskim parametrima (najmanji RSC- 79,8 %). Sukladno dobivenim rezultatima može se zaključiti da kadmij predstavlja potencijalnu opasnost jer je njegov pronos do podzemne vode u slučaju onečišćenja najizgledniji. Usporedbom analiziranih parametara tla sa sorpcijskim parametrima utvrđena je velika podudarnost, posebice sa CEC-om, Fe-oksidima i mineraloškim sastavom, koji utječu na povećanje sorpcije.

Abstract (english)

The subject of research of this master thesis is the profile of fluvial soil at the location Hlebine-Dedanovice in Podravina. The main goal of the research was to create sorption isotherms of potentially toxic metals (copper, zinc, cadmium) through the soil profile in order to determine the sorption capacity of the soil and the impact on groundwater of the study area. In order to gain insight into the process of behavior of potentially toxic metals through the studied soil profile, the following laboratory analyzes were performed: organic matter, mineralogical composition in fraction less than 2 mm, cation exchange capacity (CEC), and desired manganese oxides. Copper has shown that it has the highest sorption in the soil, sorption capacities (RSC) are very high in all layers (above 96.8%), so in case of pollution it will not be significantly transferred to groundwater. Zinc has lower sorption values than copper (the lowest RSC is 85.1%), but higher than cadmium, which showed the opposite behavior in soil with the lowest sorption parameters (lowest RSC - 79.8%). According to the obtained results, it can be concluded that cadmium represents a potential danger because its transfer to groundwater in the case of pollution is the most likely. Comparing the analyzed soil parameters with sorption parameters, a high correlation was found, especially with CEC, Fe-oxides and mineral composition, which affect the increase in sorption of potentially toxic metals in the soil.
