The dissolution of aromatic hydrocarbon compounds and polycyclic aromatic hydrocarbons from petroleum phases into water results in groundwater contamination at petroleum contaminated sites. The objective of the research is to investigate whether aging of oil-water interfaces and the formation of interfacial films retard dissolution of solutes from petroleum phases. / The equilibrium partitioning and mass transfer rates of benzene and naphthalene in oil-water systems were evaluated experimentally. The research demonstrated that: (i) the mass transfer of the solutes from Brent Blend crude oil to water is retarded when the oil-water interface is aged; (ii) visually observable interfacial films are formed between gasoline and water when amended with asphaltenes or asphaltenes and resins; (iii) the mass transfer of solutes from gasoline amended with asphaltenes or asphaltenes and resins decreased by a factor of 2.3 to 66 between 4 to 35 days of interface aging and (iv) equilibrium partitioning is not significantly affected by amending the gasoline.
