This paper describes a new method based on enhanced photoactivated luminescence (EPL) for rapid detection of polychlorinated biphenyls (PCBs). The EPL method described here is a unique procedure combining several processes including (i) photoactivation by UV irradiation, (ii) excitation of the photoproduct complex, and (iii) fluorescence detection of the product. The EPL procedure is simple and rapid and can be performed as a spot test method under field conditions. The methodology for determination of total chlorine content of complex PCB mixtures is described. Limits of detection of PCBs are in the parts-per-billion range. 14 refs., 4 figs., 1 tab.
