Polycyclcic aromatic hydrocarbons - benzo(a)pyrene: a review
Polycyclic aromatic hydrocarbons (PAHs) are a chemical group composed of more than one hundred organic compounds containing two or more condensed aromatic rings. They are produced by an incomplete combustion of organic material. Many of them, including benzo(a)pyrene (BaP), have shown to be carcinog...

| Sumario: | Polycyclic aromatic hydrocarbons (PAHs) are a chemical group composed of more than one hundred organic compounds containing two or more condensed aromatic rings. They are produced by an incomplete combustion of organic material. Many of them, including benzo(a)pyrene (BaP), have shown to be carcinogenic and mutagenic in experimental animals, and these compounds have been regarded as potentially genotoxic and carcinogenic to humans. BaP has been the most commonly subject of study, and PAH compound has been used as an indicator of total PAHs contamination. The present review describes some general topics on PAHs, mainly BaP, including the analytical methodologies for its quantification, which have been reported since 1960. Modifications on different extraction methodology and solvents, which resulted in reduction of turn-around time, solvent volumes, and analysis cost are also discussed. Chromatography techniques for PAHs and BaP quantification, such as HPLC and GC-MS are commented. |
