Abstract
The asphalt binder, derived from petroleum, commonly employed in road
paving contains PAHs (Polycyclic Aromatic Hydrocarbons) and a variety of
other aliphatic and aromatic compounds. PAHs are pollutants that can
induce health problems. This work aims to extract and characterize the
PAHs in samples of asphalt binder and its concentration. Matrix solid
phase dispersion was used as a technique for extraction of the PAHs.
Characterization was performed employing gas chromatography and scanning
tunneling microscopy. Fifteen of the priority PAHs listed by USEPA
(United States Environmental Protection Agency), as well as coronene,
were found in the binder samples.
