摘 要：In order to analyze the concentration changes of n-alkanes and PAHs in water solution of oil treated with and without dispersant, 180 fuel oil was tested with two kinds of dispersants. It was shown that addition of dispersants caused a marked increase in the concentrations of n-alkanes and PAHs in chemically enhanced water-accommodated fractions(CEWAFs) of oil compared to the untreated water-accommodated fractions(WAFs). The times of increase of concentrations were related with the type of dispersant, the dispersed oil, and the ratio of dispersant to oil. As more PAHs were dissolved in CEWAFs, the ecological risk of dispersed oil in water column should be highly concerned.
