This paper presents the development of a programmed temperature vaporization-gas chromatography-tandem mass spectrometry (PTV-GC-MS-MS) method for the determination of PAHs in complex environmental matrices. This method aims at overcoming the current problems in detecting these compounds in matrices such as
