This study analyzed the fluorometric laboratory tests for the detection of the presence of oil in seawater in cases corresponding to the real situation in the sea: when the point of seawater sampling is not in the same place as the appropriate sensor. The phenomenon of fluorescence exhibited by both natural and alien substances (oil) in the sea was used. The possibility of oil detection in the water column based on a fluorometric index (FI) extracted from the excitation-emission matrix (EEM) was studied. Laboratory tests were carried out on water taken from the Gulf of Gdańsk (Baltic Sea). Seawater samples were contaminated with small amounts of various types of oil (the lowest oil-to-water ratio was 0.5 × 10). A statistically significant difference was found between FI values for uncontaminated seawater and seawater exposed to various kinds of oil (i.e., crude oils, lubricant oils, and fuels).
本研究分析了在与海洋实际情况相符的案例中，用于检测海水中油类存在的荧光实验室测试：即海水采样点与合适传感器不在同一地点的情况。利用了海洋中天然物质和外来物质（油类）呈现的荧光现象。研究了基于从激发 - 发射矩阵（EEM）中提取的荧光指数（FI）来检测水柱中油类的可能性。对取自格但斯克湾（波罗的海）的水样进行了实验室测试。海水样本被少量各种类型的油污染（最低油水比为0.5×10）。未受污染的海水与接触各种油类（即原油、润滑油和燃料）的海水的FI值之间存在统计学上的显著差异。
