Light attenuation parameters of polydisperse oil-in-water emulsion

This paper presents the method and the results of modelling the fight attenuation and absorption spectra in sea water polluted with dispersed oil. The Mie solution has been employed in modelling to derive the cross-sections of light attenuation and its components, absorption and scattering of oil-water emulsion droplets. After the averaging for typical distributions of dispersing particles, these cross-sections allow determination of the optical properties of water polluted with oil substances. It was revealed that oil concentration of about 1 ppm in water causes light attenuation comparable with attenuation in natural water typical for bays of the Baltic Sea (Case 2 waters The method presented facilitates obtaining the information necessary for the modelling of above water upward radiation field in the cases of basins polluted with dispersed oil
