Summary It is demonstrated by simulated environmental factors that after the application of petroleum onto a water surface, alterations in the distribution pattern are primarily caused by evaporation. During 8 h of analysis, it has been shown that evident loss by evaporation occurs especially for low-molecular n-alkanes, where the evaporating velocity is dependent on the film thickness, water temperature and wind velocity. Quantitatively, the concentration decrease of n-alkanes, nonane to pentadecane as well as pristane was determined by capillary gas chromatography with flame ionization detection at different periods of time, different water temperature and film thickness. A simple, rapid and cost-effective method for column chromatographic separation of low-boiling petroleum is also presented. By means of this method, it is possible to separate aliphatic, mono-, di- and polyaromatics from petroleum. The following gas chromatographic separation of the three fractions is simplified by removal of the non-volatile components.
