Overview

Laboratory simulation reveals rapid weathering kinetics of heavy fuel oils in tropical coastal media, indicating robust biomarker stability for decadal environmental forensics.

Key Points

To quantify the chemical evolution, weathering kinetics, and forensic longevity of sequestered heavy fuel oils in tropical coastal environments.
Conducted a high-resolution 48-week laboratory simulation at 25 °C using Teh Shiang Taipei and Tzimini heavy fuel oils.
Analyzed chemical composition and degradation dynamics over time using gas chromatography-mass spectrometry (GC–MS).
Observed rapid chemical progression of heavy non-aqueous phase liquids to an advanced weathering stage under simulated tropical conditions.
Detected near-complete depletion of highly mobile n-alkanes during the weathering process.
