Sorrell and Reding [179] present an extension of this technique, for analysing l-3ng L 1 amounts of 15 polynuclear aromatic hydrocarbons in environmental water samples using high performance liquid chromatography, preceded by a clean-up using alumina, with ultraviolet monitoring and fluorescence emission-excitation spectra for identification.

Miscellaneous Methods for Oil Identification. High-pressure liquid chromatography has already been mentioned in conjunction with rapid fluorescence detection. It fully characterizes the polar fractions containing the polynuclear aromatic hydrocarbons and could be of use in those cases where their overall fluorescence fingerprint cannot distinguish between two oils. 

Identification of the Fluorescent Species. Figure 2 compares the fluorescence excitation spectra of the polymers with the absorption spectrum of a simple ,/3-unsaturated carbonyl compound (pent-3-ene-2-one) (13). The three spectra are very similar. Figure 2 shows also that the fluorescence from the polymers in the region 300-400 nm cannot be caused by the presence of polynuclear aromatic hydrocarbons such as naphthalene as postulated earlier by Carlsson and Wiles (13). Furthermore, as shown below, the excitation spectrum also differs significantly from that of a fully saturated aldehyde or ketone. 

During the past 7 years, we have developed and applied new methodologies using capillary-column GC for the separation and identification of PACs in coal-derived liquids. The primary samples that were used throughout these studies included a solvent-refined coal (SRC II) heavy distillate and a coal tar. Details of the isolation and identification of polynuclear aromatic hydrocarbons (PAHs) (II), sulfur heterocycles (12, 13), nitrogen heterocycles (14,15), amino- substituted PACs (16-18), and hydroxy-substituted PACs (14, 19, 20) in an SRC II heavy distillate have already been published (II, 13, 15, 18, 21).

Polycyclic organic matter, derived from the total exhaust emission, is an extremely complex mixture. It includes a large number of compounds such as polynuclear aromatic hydrocarbons (PAH), derivations of PAH such as nitro-PAH and amino-PAH, oxygenated PAH such as phenols and quinones, and heterocyclic aromatic compounds containing sulfur and oxygen. In order to assist in the identification of classes of toxic compounds it is possible to fractionate the exhaust emissions into vapor and...

Bay, Massachusetts. Gas liquid chromatography was used to detect hydrocarbons present at different depths in the sediment, while low resolution mass spectrometry was employed to measure concentrations of paraffins, cycloparaffins, aromatics and polynuclear aromatics. Their data show that the concentrations of total and saturated hydrocarbons decreased with increased depth, and it was noted that identification and quantification of hydrocarbons in oil-contaminated sediments is required if the fate of these compounds in dredge spills is to be determined.
