| Abstract in Brazilian Portuguese: | O ligante asfáltico de petróleo é comumente empregado na pavimentação de ruas e estradas de rodagem. Esse material contém hidrocarbonetos policíclicos aromáticos (HPAs) e diversos outros componentes alifáticos e aromáticos. Os HPAs são compostos poluentes que podem induzir problemas de saúde. Este trabalho tem como objetivo extrair e caracterizar os HPAs presentes no ligante asfáltico e suas concentrações. Dispersão de Matriz em Fase Sólida foi utilizada como técnica para a extração dos HPAs. Para análise e caracterização foram utilizadas as técnicas de Cromatografia Gasosa e Microscopia de Tunelamento. Quinze dos HPAs prioritários listados pela USEPA (United States Environmental Protection Agency) e também coroneno foram encontrados nas amostras analisadas. |
| 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. |
