Synchronous ultraviolet-visible (UV-vis) fluorescence spectrometry is currently being evaluated as a field screening technology by the US Environmental Protection Agency`s (EPA) Environmental Monitoring Systems Laboratory in Las Vegas, Nevada (EMSL-LV). This method can provide compound or class-selective results on site at a reasonable cost. A prototype field-portable spectrofluorometer capable of excitation, emission, and synchronous scans was field tested at the American Creosote Works Superfund Site (a wood preservation facility) in Jackson, Tennessee. The instrument was also tested in the laboratory with sediment samples collected from Antarctica. The UV-vis fluorescence spectra of various polycyclic aromatic hydrocarbons (PAHs) were clearly seen in the synchronous spectra of soil samples extracted on site at American Creosote Works. The spectra for the Antarctic sediment samples were nearly identical to that of motor oil. The results of this study demonstrate the utility of synchronous fluorescence to provide evidence of the presence and identity of hydrocarbon contamination in environmental samples. The technique allows flexibility in selection of optimum extraction and instrumental procedures for site-specific matrices.
