Facilitated solubilization of polynuclear aromatic hydrocarbons by the cosolvent effect of oxygenated fuel additives and alternative fuels
- Univ. of Florida, Gainesville, FL (United States)
Oxygenated and alternative fuels become popular because three different alternative fuel programs have been mandated in the 1990 Clean Air Act Amendments to minimize combustion-related pollution. The alternative fuels have brought increased interest in the transport and fate of miscible organic liquids in the subsurface and the effect that these liquids have on the transport and fate of other contaminants. The addition of polar organic solvents that are completely miscible or highly soluble in water to a mixture of hydrocarbons and water has the potential of showing the cosolvent effect. Therefore, the use of oxygenated and alternative fuels leads to cosolvency becoming an important issue. The objective of this research is to investigate the redistribution and facilitated transport of hydrophobic organic compounds (HOCs) from contaminated sediment caused by cosolvent effects due to potential oxygenated/alternative fuel spills. Specifically, the phase redistribution of HOCs in aqueous and sediment systems upon the addition of oxygenated and alternative fuels is investigated. This study is expected to provide the basis to predict fate parameters (i.e., dissolution, sorption) for the facilitated transport of HOCs due to cosolvent effects of oxygenated additives and alternative fuels. These fate parameters will allow further assessment of the environmental and health effects of spills and leaks of oxygenated and alternative fuels.
