Fluorescence based detection of polychlorinated biphenyls (PCBs) in water using hydrophobic interactions.

ABSTRACT: Despite increasing controls in their production and disposal, persistent organic pollutants in water, even at concentrations below parts per million, represent an ongoing environmental health risk. Despite this concern, the detection of these compounds in water sources rely upon expensive, time consuming approaches that do not permit frequent monitoring and evaluation. In this work, a new fluorescence-based technique is presented for the detection of polychlorinated biphenyls (PCBs) in water. Benzopyrene (BaP) fluorescence was shown to increase with trace concentrations of aromatic organic pollutants. BaP forms a hydrophobic complex with PCBs, which has allowed for the successful detection of pollutants including PCB-126, PCB-153 and PCB-118. To determine the selectivity and robustness of
