Abstract
Abstract − Once oil is spilled into marine environment, it experiences various weathering processes amongwhich evaporation is the most dominant process in the initial stage of weathering. This study aimed to elucidatethe effects of evaporation on the physicochemical properties of spilled oil using standardized laboratory exper-iments. Laboratory evaporation process was successfully reproduced using controlled rotary evaporationmethod. In case of Iranian Heavy crude (IHC), evaporation rate after 48 hours was 29.3±0.4% (n=40, p <0.001).Evaporation was simulated using ADIOS2 weathering model and the result was in agreement with laboratoryexperiment. Chemical composition changes of petroleum hydrocarbons including alkanes, polycyclic aromatichydrocarbons (PAHs) and biomarkers by evaporation rate were also analyzed. As oil evaporated, low molecularweight alkanes and PAHs decreased, while biomakers showed conservative characteristics. Among biomarkers,17 α (H), 21 β (H)-hopane was used for calculation of weathering rates, which matched with evaporative masslosses. Weathering rate calculation using hopane showed that stranded oils of weathering stage I (28.9%) andmesocosm oil weathering experiment till 5 days (26.5%) were mainly affected by evaporation process.Keywords: Iranian Heavy Crude oil(이란산중질원유 ), Evaporation(증발), Rotary evaporation method(회전증발법), Weathering rate(풍화율), Biomarker(바이오마커 )
