Laser-induced, time-resolved fluorescence spectroscopy may be useful in the detection and quantification of polycyclic aromatic hydrocarbons (PAH) in seawater and sediments. Several PAH have relatively long-lived stimulated fluorescence emissions, which allow them to be detected among a background of more intense but shorter-lived chromophores. Using time-delayed techniques the authors of this study have shown an ability to detect PAH, principally pyrene, at environmental levels both in the laboratory and in situ in Boston Harbor and other study areas. Further development may lead to the rapid determination of several PAH in typical near-shore marine environments.
