应用激发发射矩阵光谱（EEMS）来确定荧光指数（FI），作为指示海洋特定区域存在石油污染源的参数。在这项研究中使用了波兰海岸（波罗的海）的海水和从波罗的海大陆架提取的不同数量的原油（波罗的海型油）。考虑天然海水和人工污染海水（油水比范围为0.5 × 10−6 ~ 500 × 10−6），计算最大峰处激发和发射波长的FI值。FI指数采用了波长配置（Ex/Em）（225/355和225/340）。研究发现，与油的含量无关，天然海水的FI值高于与油接触的海水。这些结果为设计在特定海域发出石油外观信号的传感器提供了基础。
Excitation-emission matrix spectroscopy (EEMS) was applied to determine the fluorometric index (FI) as a parameter indicating the presence of a source of oil pollution in a specific area of the sea. Seawater from the Polish coast (the Baltic Sea) and the same water combined with various amounts of crude oil extracted from the Baltic Sea shelf (Petrobaltic-type oil) were used in this study. The FI values were calculated for excitation and emission wavelengths found at the maximal peak, taking into account the natural seawater and the seawater artificially contaminated (for an oil-to-water ratio range of 0.5 × 10−6 − 500 × 10−6). The wavelength configurations (Ex/Em) (225/355 and 225/340) for the FI index were applied. It was found that, independent of the amount of oil, the FI achieves a higher value for natural seawater than for seawater that has had contact with oil. These results provide the basis to design a sensor signaling the appearance of oil in a defined sea area.
