Abstract
Onesnaženje tal je v svetu pereča tematika, še posebej če so tla v kmetijski rabi in se na njih prideluje hrana. S pojavljanjem onesnažil so se razvijale tudi metode, s katerimi odstranjujemo onesnažila in onesnažena zemljišča saniramo. Metode za odstranjevanje organskih onesnažil večinoma temeljijo na njihovi pospešeni razgradnji, pri čemer se lahko uporabijo biološki, termični, kemični, fizikalni ali elektrokemijski postopki. Znanstveniki poizkušajo razviti metode, ki bi povzročile čim manjši stres oziroma čim manj vplivale na prisotni ekosistem. Ločimo metode, ki jih izvajamo na lokaciji zemljišča (in –situ) in metode, kjer tla odstranimo in jih saniramo na drugi lokaciji v reaktorjih (ex-situ). Slednje so povezane s transportom, večjimi stroški in imajo lahko negativen vpliv na sanirano območje. Izbira metode mora temeljiti na analizah primernosti in lahko vključuje eno metodo ali kombinacijo več metod. Uporaba živih organizmov (bioremediacija), se izkazuje za primerno metodo iz vidika čim manjšega vpliva na ekosistem. Namen diplomske naloge je na osnovi rezultatov objavljenih raziskav podati pregled metod za čiščenje tal, onesnaženih z organskimi onesnažili. Osredotočili se bomo na učinkovitost in primernost za različne skupine organskih onesnažil

Title:Sanation of soils polluted with potentially hazardous organic substances
Abstract:
Soil pollution is an alarming issue in the world, especially if the land is used for agriculture and food growth. With the greater occurrence of pollutants in general, more methods are beeing developed to remediate or remove them. Methods for removing organic pollutants are mostly based on their induced degradation by biological, thermal, chemical, physical or electrochemical processes. Scientists are trying to develop methods that cause minimal stress or cause as little impact on the ecosystem as little as possible. We distinguish between methods that are carried out at the site of the soil (in-situ) and methods where the soil is removed and remediated at another site in the reactors (ex-situ). The latter are associated with transport and higher costs and can have a negative impact on the remediated area. The choice of method should be based on suitability analyzes and may involve one method or a combination of several methods. The use of living organisms (bioremediation) proves to be a suitable method from the point of view of minimizing the impact on the ecosystem. The aim of the diploma thesis is to give an overview of methods for cleaning soils contaminated with organic pollutants, based on the results of published research. We will focus on the effectiveness and suitability for different groups of organic pollutants.
