We evaluated the performances of a submersible ultraviolet fluorometer (EnviroFlu-HC, TriOS Optical Sensors) dedicated to the real time measurement of polycyclic aromatic hydrocarbons (PAHs) in the aquatic media. We conducted calibration experiments and in situ measurements in the coastal Mediterranean Sea. We found that the EnviroFlu-HC was not strictly specific to PAHs, even though it exhibited the highest sensitivity for phenanthrene, but could response to tryptophan-like material as well, and in a much less extent, to humic substances. The sensor signal showed great spatial and temporal variations in clean and polluted sites, with likely a high contribution of PAHs in the harbors, and a high contribution of tryptophan-like and humic-like materials in the sewage effluent. We conclude that the EnviroFlu-HC is a good tool for monitoring anthropogenic inputs in the coastal waters, although its utilization should be combined to other fluorescence measurements to improve the information about the nature of the aromatic compounds detected.
我们评估了一款潜水式紫外荧光仪（EnviroFlu-HC，TriOS Optical Sensors）的性能，该仪器专门用于实时测量水介质中的多环芳烃（PAHs）。我们在地中海沿海进行了校准实验和原位测量。我们发现，尽管 EnviroFlu-HC 对菲表现出最高的灵敏度，但它对多环芳烃的特异性并不严格，而且还可以响应色氨酸样物质，但程度要低得多，还可以响应腐殖质。在清洁和污染的地点，传感器信号显示出很大的时空变化，港口中可能有大量的多环芳烃，而污水排放中则有大量的色氨酸样和腐殖质样物质。我们得出结论，EnviroFlu-HC 是监测沿海水域人为输入的一种很好的工具，尽管它的使用应该与其他荧光测量相结合，以提高有关所检测芳香族化合物性质的信息。
