The solar energy influence on light attenuation coefficient (LAC) spectrum and particle size distribution (PSD) of laboratory crude oil-seawater emulsion was investigated. It was demonstrated that light facilities dispergation of emulsion and cauises the increase of LAC in ultraviolet range during storing.PSD of crude oil droplets (d ? 0.5 ?m) in emulsion did not depend on lighting conditions during storing of emulsion.Because of increase of lighy attenuation coefficient selectivity for illuminated emulsion, the increase of number of small droplets (d ?0.5 ?m) of crude oil is highly probable.
Results of investigation carried out on 'mechanical' and 'acoustical' emulsions of Baltic crude oil in artificial Baltic seawater are presented.It was demonstrated that the 'acoustical' emulsions are equivalent to the steady-state of 'mechanical' emulsions obtained at frequencies similar to those of waves induced by wind. It is shown that measurements of transmissivity in the visible region can be applied in the determination of dimensions of oil microdroplets
The presented article is an effort to sort out the interpretation of experimental results concerning changes of light attenuation coefficient in seawatee which was polluted with crude oil in a controlled way.In particular, approximations of measurements results by selected theoretical curves are performed, and basing on the interpretation of the curves' parameters, the conclusions about optical properties of the madium are drawn.
