Investigates oil weathering effects on non-hydrocarbon elements and their diagnostic potential in marine ecosystems, suggesting practical applications for oil spill identification.
Key Points
The aim is to investigate the weathering behavior of non-hydrocarbon elements in different oil types and assess their diagnostic potential for oil spills.
Analyzed Omani crude oil, 95 RON gasoline, and grade 0 diesel using ICP-OES.
Evaluated stability of non-aromatics to total aromatics (NA/TA) via HPLC.
Conducted tests with and without artificial seawater to observe effects on oil properties.
Density of 95 RON gasoline increased by 12.44% with seawater; Omani crude oil by 4.94%; grade 0 diesel by 0.34%.
Sulfur content in Omani crude oil increased by 35.59% with seawater, while 95 RON gasoline showed a 32.99% decrease.
NA/TA ratio provides reliable diagnostic indicator for oil spills, simplifying sample preparation compared to GC/MS.
