Opis:: The paper presents some results of research on the fluorescence properties of petroleum oil-in-water emulsions. The research addresses the question of measuring and modelling light fields in an oil-polluted marine environment. The fluorescence of the emulsion manifests itself in the spectral range from 260 to over 400 nm and is much less intensive in the visible light region. Fluorescence is always weaker than the radiation scattered in an emulsion. The measurement and modelling of ultraviolet radiation scattering requires fluorescence to be taken into consideration, but in the visible spectral region this phenomenon is negligible.

Opis:: The paper analyses the optical properties of a crude oil –sea water emulsion, which is a form of petroleum pollution of the sea. These properties depend on the spillage concentration, the optical characteristics of the seawater and oil in question, and on the size distribution of the oil droplets. They may be described by the attenuation specific cross-sections and absorption specific cross-sections. Specific cross-sections and other optical parameters for droplets of a Baltic crude oil –Bal tic seawater emulsion were calculated using Mie’s solution. These characteristics were computed for fresh and weathered petroleum.

Opis:: The paper presents an improved method of determining petroleum pollutants in water based on fluorescence, which allows the oil content to be estimated with an accuracy better than 50%. The method was used to measure the oil content in Gulf of Gdańsk seawater sampled at Gdynia-Orłowo between January 2006 and September 2008. The 174 measurements made during this period ranged from 1 to 120 μg kg−1, but the majority did not exceed 20 μg kg−1. The most probable level of contamination is c. 5 μg kg−1.
