Migracija dizel goriva izlivenog u slojeve zemljišta / Migration of diesel fuel spilled in subsurface layers of soil

U radu su prikazane osnovne fizičko-hemijske karakteristike dizel goriva i zemljišta. Objašnjena je migracija izlivenog naftnog zagađivača kroz vertikalni profil zemljišta. U eksperimentalnom delu ispitivane su koncentracije dizel goriva i relativne koncentracije n-alkana u površinskim slojevima peska, u koje gorivo dospeva kao posledica akcidentnog izlivanja. Utvrđeno je da se koncentracije dizel goriva menjaju sa vremenom nakon izlivanja u svim ispitivanim slojevima. Takođe, utvrđeno je da se dizel gorivo, kao potencijalni zagađivač, u prvih šest nedelja, uglavnom, zadržava u površinskom sloju dubine 30 cm, a objašnjene su i mogućnosti sanacije zagađenog zemljišta. / The basic physical and chemical properties of both diesel fuel and soil have been given in this article and oil pollutants migration through vertical soil profile have been explained as well. In the experimental part of the paper both the concentrations of diesel fuel and relative concentrations of n-alkynes spilled in sandy soil by accident have been investigated. It has been proven that the concentrations of diesel fuel have changed in all layers of soil depending on the time after spill. Diesel fuel as possible pollutant has been retained 30 cm deep in sandy soil during six weeks after spill. Finally, cleanup techniques of polluted soil have been explained.
