Abstract
Tijekom procesa proizvodnje glinice jedan od najopasnijih nusprodukata jest crveni mulj. Velike količine crvenog mulja odlažu se u sklopu tvornica na otvorenom u velikim, plitkim bazenima što u kontaktu s okolinom, čak i desetljećima nakon njihovog zatvaranja, može imati vrlo negativne posljedice zbog visoke alkalnosti te prisutnosti raznih (teških) metala u njegovom sastavu. Nekadašnja tvornica glinice Jadral nalazi se na obrovačkom području u čijoj geološkoj građi prevladavaju mezozojske i... More paleogneske sedimentne stijene dok se u neposrednoj blizini nalazi estuarij rijeke Zrmanje, a cijelo područje izloženo je jakim vjetrovima. Primjenom kiselog reagensa (pH=2,87) na uzorcima tla uzorkovanih na području tvornice simulirana je pojava kiselijeg ispiranja u okolišu te su određene ukupne koncentracije metala u tlima i pridruženim eluatima u četiri veličinske frakcije (<0,45μm, <0,2μm, <0,1μm, <0,008μm). Rezultati pokazuju kako sama tla imaju puferirajući učinak, a mobilnost metala varira u ovisnosti o kationskom/anionskom karakteru te o njihovoj prisutnosti u pojedinim mineralima. Smjer prijenosa metala definiran je dominantnim vjetrom koji prevladava - bura. U kiselim uvjetima najmobilniji su elementi s kationskim karakterom vezani za karbonate (Sr, Mn, Cd), dok elementi s anionskim karakterom u kiselom mediju nisu značajno mobilni. Less
Abstract (english)
During the alumina production process, one of the most dangerous by-products is red sludge. Large amounts of red sludge are disposed of in factories outdoors in large, shallow pools, which in contact with the environment, even decades after their closure, can have very negative consequences due to the high alkalinity and the presence of various (heavy) metals in its composition. The former Jadral alumina factory is located in the Obrovac area, whose geological structure is dominated by... More Mesozoic and Paleogene sedimentary rocks. The estuary of the Zrmanja river is located in the immediate vicinity and the entire area is exposed to strong winds. By applying an acidic reagent (pH=2.87) to soil samples sampled in the factory area, the occurrence of acidic leaching in the environment was simulated, and the total concentrations of metals in soils and associated eluates were determined in four size fractions (<0.45μm, <0.2μm, <0.1μm, <0.008μm). The results show that the soils have a buffering effect and the mobility of metals varies depending on the cationic/anionic character and their presence in certain minerals. The direction of metal transfer is defined by the prevailing wind - bora. In acidic conditions, the most mobile elements are ones with a cationic character and bound to carbonates (Sr, Mn, Cd), while the elements with an anionic character are not significantly mobile in an acidic medium.
