Polycyclic aromatic compounds (PAHs, PCBs) are widespread contaminants usually investigated in sediments, which act as sinks for these toxic persistent lipophilic compounds. Conventional approaches often use gas chromatography coupled to mass spectrometry (GC-MS) as a powerful tool to separate, identify and quantify them, but a preliminary step of extraction is required. The latter generally necessitate the use of toxic organic solvents and extend the duration of the overall analytical process, particularly for sediment cores analyses.
