Abstract
Rad obraĊuje problematiku oneĉišćenja tla iz bivšeg rudnika olova i cinka u Meţanskoj dolini u susjednoj Sloveniji. Tijekom dugogodišnje rudarske i industrijske djelatnosti u dolini rijeke Meţe, tlo je postalo skladište otpadnih tvari rudnika koje sadrţe teške metale. Djelovanjem oborina nastajale su i procjedne vode, pomoću kojih su se štetne tvari širile dalje u podzemne vode i tako zagaĊivale okoliš. U ovom radu je provedeno preliminarno istraţivanje ispiranja kontaminiranog tla dobivenog s Geološkog zavoda Slovenije koji se bavi mapiranjem oneĉišćenja okoliša kao posljedica rudarenja. Rezultati su potvrdili kako oneĉišćeno tlo sadrţi koncentracije teških metala veće od dozvoljenih koncentracija propisanih zakonom za poljoprivrednu proizvodnju. Naša ispitivanja su provedena ispiranjem oneĉišćenog tla u ultraĉistoj vodi pri razliĉitim pH vrijednostima. Vremensko praćenje ispiranja olova, cinka i mangana je izvedeno pri pH = 4,6. U otopinama dobivenim ispiranjem odreĊena je koncentracija prisutnih teških metala metodom atomske apsorpcijske spektrometrije. Rezultati su pokazali ispiranje cinka i olova u vrlo kratkom vremenu, dok se mangan ispire sporije ali kontinuirano. Koncentracije olova prelaze dopuštene vrijednosti za ispust otpadnih voda u okoliš. Kako bi se sprijeĉilo otpuštanje teških metala iz ovakvih izvora, bitno je provesti remedijaciju tla, koja ukljuĉuje razne fizikalne, biološke, kemijske i termalne procese.
Abstract (english)
The thesis deals with soil pollution surrounding mine of lead and zinc in Meţa valley in neighbour country Slovenia. During long term mine and industrial activities in Meţa valley, surrounding soil become storage place of waste materials containing heavy metals. The rain and other climate conditions which cause leaching have formed underground wastewaters which pollute environment. In this thesis is examined preliminary research of leaching of the contaminated soil given from the Geological Survey of Slovenia which examines mapping of the soil pollution from mine sources. Results have confirmed concentration of heavy metals higher than allowed for agricultural purposes. Our investigations include leaching of the soil in ultrapure water at different pH values. Monitoring of the leaching experiments are performed at pH=4.6. In produced leachates are determined heavy metals concentrations using atomic absorption spectrometry. Results have shown leaching of zinc and lead in very short contact time, while manganese releases slow and continuously. Lead concentrations were higher than allowed for discharge of these wastewaters into environment. In order to prevent leaching of contaminated soils is necessary to perform soil remediation using different available treatments such as physical, biological, chemical and thermal processes.
