Application of ultraviolet fluorometry and excitation–emission matrix spectroscopy (EEMS) to fingerprint oil and chemically dispersed oil in seawater

Change of seawater fluorescence properties when mixing with crude oil

“…The spectral ranges generally correspond to the results in [13] for other oil grades. The dashed lines show spec tral regions characteristic of the natural conditions of Russian Far Eastern seas, where intensity maxima are regularly observed [12]: H1 and H2 are the fluores cence regions of humin compounds, P1, of protein compounds, CA, of chlorophyll a, and NP, of pheny lalanine, possibly [14][15][16][17].…”

Physical and Chemical Characterization of Crude Oil-Water Mixtures: Understanding the Effects of Interfacial Process to Chemical Bioavailability

“…There is a clear difference between the preparation that contain the oil droplets (Zhou et al, 2013). Bugden et al (2008) and others have attributed the emission peaks at 340 nm to be a characteristic of the more water soluble low and medium molecular weight aromatics, while the emission peak at 445 nm is probably associated with the higher molecular weight (≥3-ring) aromatics. …”

Fluorescence Spectroscopy as a Potential Tool for In-Situ Monitoring of Dissolved Organic Matter in Surface Water Systems

“…It has been established, so far, that this technique can characterize natural organic matter (Baker and Spencer, 2004;Winter et al, 2007) and detect different types of aquatic pollutants, like sewage (Baker, 2001;Reynolds, 2002), oil (Budgen et al, 2008;Patra and Mishra, 2002;Carstea et al, 2010) or pesticides (Jiji et al, 2000). Furthermore, DOM fluorescence data correlate with water quality parameters such as: total organic carbon (Vodacek et al, 1995), aquatic plankton (Mopper and Schultz, 1993), faecal coliforms (Pfeiffer et al, 2008) and biological oxygen demand (Reynolds and Ahmad, 1997;Hudson et al, 2008).…”
