This study is a continuation of analyses of the fluorometric index (FI), based on the fluorescence of substances of oil origin, as an indicator of oil in a seawater column. The effectiveness of the FI in the cold season (late autumn, winter and early spring) for the coastal water in the southern Baltic Sea was assessed. FI was tested for seawater polluted with a mixture of crude oils, lubricating oils and fuels. Laboratory analyses of oil-water systems for low (reaching the limit of detection) oil content in seawater were performed. The influences of the natural components of seawater that disrupt oil detection are discussed. The ability to detect oil in a seawater column regardless of the season was confirmed.
本研究是基于油源物质荧光的荧光指数（FI）分析的延续，作为海水柱中石油的指示剂。评估了 FI 在波罗的海南部沿海寒冷季节（晚秋、冬季和早春）的有效性。FI 用于测试受原油、润滑油和燃料混合物污染的海水。对海水中低油含量（达到检测限）的油水体系进行了实验室分析。讨论了干扰油检测的海水天然成分的影响。证实了无论季节如何都能检测到海水柱中石油的能力。
