“…Two types of specially-designed instruments, namely a battery-operated portable synchronous luminescence spectrofluorometer and a portable synchronous scanning luminoscope, were developed for on-site analysis of soils, waste sites and ground water contaminated by PCBs and other aromatic pollutants [76,77]. Also, a simple, enhanced photoactivated fluorescence method on solid substrates was described by Vo-Dinh et al [78,79] for rapid screening of PCB congeners and Aroclor mixtures. This method combined several steps, including photoactivation by UV irradiation, excitation and fluorescence of the formed photo-product, and led to LODs in the ppb range for PCBs.…”

The analytical performances and applications of various luminescence spectrometric methods to the study and determination of pollutants present at low levels in the environment are reviewed for the last two decades (1990 – 2010). The first part concerns luminescence stationary systems, including fluorescence, photochemically-induced fluorescence, phosphorescence and related luminescence methods. In the second part, the combination of these luminescence methods with flow techniques such as high performance liquid chromatography (HPLC), capillary electrophoresis (CE) and flow injection analysis (FIA) for the detection and determination of environmental pollutants is investigated. A part of the review is also devoted to the usefulness of organized supramolecular systems, such as micellar media, cyclodextrins and calixarenes, for improving the efficiency of luminescence methods.

“…Several works (3)(4)(5)(6)(7)(8)(9)(10)(11) have shown that it is possible to avoid elution of the solid phase and chromatographic steps by performing a simple spectroscopic detection of hydrophobic aromatic pollutants from the aqueous medium directly on an appropriate solid phase after extraction.…”

A method for the detection of PCBs in water, based on extraction/concentration with tab-shaped elements cut from C18 fiberglass SPE disks coupled with a fluorescence detection has been applied to natural waters. Due to the known complexing property of the naturally present Natural Organic Matter (NOM) with respect to non polar organic pollutants, NOM was shown to compete with the solid phase for PCB adsorption thus reducing the capability of the method.In order to obviate the negative effect of NOM on the sensitivity of the method, a prior oxidation treatment with KMnO 4 was tested on PCB3, PCB77 and Aroclor 1221. This pretreatment was also tested for the detection of pyrene, perylene and benzo [a]pyrene taken as representative polycyclic aromatic compounds.In all cases, with respect to the signal in pure water and depending on the dissolved organic carbon concentration 407 408 R. Belfatmi et al. (DOC), the signals with no treatment could be lowered to less than 20%, while the signals obtained following oxidative treatment was found to be very close with more than 90% of recovery.
