Polycyclic aromatic hydrocarbons from asphalt binder: extraction and characterization (original) (raw)

Asphalt binder, a complex mixture derived from crude oil, poses health risks due to the release of hazardous compounds, notably polycyclic aromatic hydrocarbons (PAHs), during its application. This study introduces a novel extraction method, matrix solid phase dispersion (MSPD), for isolating 16 priority PAH compounds from asphalt binders, subsequently analyzed using gas chromatography (GC) and characterized using scanning tunneling microscopy (STM). The findings enhance understanding of PAH profiles in asphalt and highlight the potential for using MSPD in evaluating environmental contamination.
