“…Both unburned and combusted fossil fuels impart unique PAH signatures in the marine environment (Bidleman, Castleberry, Foreman, Zaranski, & Wall, 1990;Bieger, Hellou, & Abrajano, 1996;Bixian et al, 2001;Boehm & Farrington, 1984;Bouloubassi & Saliot, 1993;Countway, Dickhut, & Canuel, 2003;Hites, LaFlamme, & Windsor, 1980;Maruya, Risebrough, & Horne, 1996;Mazeas & Budzinski, 2001;Oros & Ross, 2004;Prahl, Crecelius, & Carpenter, 1984;Wakeham, 1996). Petroleum derived PAH are preferentially biodegraded compared to combustion derived PAH (Jones, Rowland, Douglas, & Howells, 1986).…”

“…Most studies on petroleum hydrocarbon contamination in coastal seas and estuaries have concentrated on North America and Europe (Gordan et al, 1978;Marchand et al, 1988;Bidleman et al, 1990;Zhang et al, 1993;Rajkumar and Persad, 1994;Law et al, 1997;Sharma et al, 1997;Woodhead et al, 1999;Soclo et al, 2000;Notar et al, 2001). There are few studies from Southeast Asia, where industrialization and urbanization have proceeded rapidly in the past four decades (Table 1).…”

Dissolved or dispersed petroleum hydrocarbon concentrations (DDPH) were monitored in Ponggol estuary, Singapore, fortnightly from July 1999 to June 2000. DDPH concentrations ranged from 4.4 to 248.9 microg l(-1) and 0.4 to 1099.7 microg l(-1) for surface and subsurface waters, respectively and with mean concentrations of 41.01 microg l(-1) in the water column. Absorbed or adsorbed petroleum hydrocarbon (AAPH) concentrations measured in sediments ranged from 20.6 to 541.0 mg kg(-1), with mean concentrations of 148.23 mg kg(-1). In situ mesocosm studies of bacteria and phytoplankton were based on field monitoring of environmentally measured concentrations of petroleum hydrocarbons, using diesel fuel as the source of contaminant. The mesocosm comprised of 25 L clear polycarbonate carboys incubated in situ for 6 days. Water and sediments from a clean site with undetectable levels of petroleum hydrocarbons were used in controls. The treatment mesocosms comprised of mean and highest concentrations of DDPH and AAPH. The study revealed signs of acute toxicity to autotrophs viz., phytoplankton and autotrophic bacteria in treatments simulating concentrations of diesel fuel found in the sediments. A stimulatory effect was seen at lower concentrations. Bacterial heterotrophs responded positively to all concentrations of diesel fuel because of the abundance of a carbon source, reduced grazing pressure and reduced competition for nutrients from phytoplankton.

“…Crude oil contains diverse hydrocarbons and organic molecules that could contribute to UV absorbance and fluorescence signatures in seawater and could be readily determined and characterized by UV-vis spectroscopy and fluorescence spectroscopy techniques [16][17][18][19][20][21]. Similarly, the composition and sources of dissolved organic matter (DOM) in aquatic environments can be effectively characterized by its optical properties, including UV-vis absorbance and fluorescence EEM spectra [22][23][24][25][26][27][28][29][30], especially when combining the application of PARAFAC modeling [31][32][33][34][35][36].…”

The fluorescence excitation-emission matrix (EEM) technique coupled with parallel factor (PARAFAC) modeling and measurements of bulk organic carbon and other optical properties were used to characterize the oil components released from the Deepwater Horizon oil spill in the Gulf of Mexico and to examine the chemical evolution and transformation of oil in the water column. Seawater samples were collected from the Gulf of Mexico during October 2010 and October 2011, three months and fifteen months, respectively, after the oil spill was stopped. Together with previous results from samples collected during the oil spill in May/June 2010, these time series samples allow us to elucidate changes in the optical properties of dissolved organic matter (DOM) from the time of maximum oil impact to its recovery, 15 months after the spill. Although the oil had profoundly altered the optical properties of the DOM in the entire water column during the oil spill, naturally occurring DOM became predominant in surface waters by October 2010, three months after the spill. Anomalous DOM with high optical yields, however, still resided in deep waters even 15 months after the oil spill in October 2011, showing a persistent influence of the oil in deep waters. Based on fluorescence EEM data and PARAFAC modeling, three oil components and one natural humic-like DOM could be readily identified. The most prominent oil component had its maximum fluorescence intensity at Ex/Em 224/328 nm, and the other two centered on Ex/Em 264/324 and 232/346 nm, respectively. The humic-like DOM component had its wide emission peak from 390 to 460 nm over the excitation wavelength at ∼248 nm. We hypothesized that component-2 (264/324 nm) was mostly derived from photochemical degradation and the component-3 (232/346 nm) could be a degradation product from both microbial and photochemical degradation, although both C2 and C3 are subject to degradation at different rates. The oil component ratios, such as C2/C1 and C3/C1, were closely related to degradation states of oil and can be used as a sensitive index to track the fate, transport and transformation of oil in the water column.
