The Use of Synchronous Fluorescence Technique in Environmental Investigations of Polycyclic Aromatic Hydrocarbons in Airborne Particulate Matter from an Industrial Region in Poland

Abstract: The applicability of the fluorescence techniques to identify the polycyclic aromatic hydrocarbons (PAHs) in environmental samples is presented. The technique of synchronous fluorescence enabled the identification of the PAHs series containing 2-6 condensed rings in urban airborne particulate matter from Upper Silesia industrial region in Poland. The results obtained by synchronous and conventional fluorescence measurements have been confirmed by those from gas chromatography-mass spectrometry. As the air sampl… Show more

“…Fluorescence emission spectra (corresponding to the number of rings from one to four) can be found at such wavelengths as 275-320 nm, 320-375 nm, 375-425 nm and 425-556 nm. Moreover, the mixture of absorbing and fluorescing polycyclic aromatic hydrocarbons in aqueous matrices becomes complex because of the energy degrading/quenching phenomena such as self-quenching, the reabsorption of emitted photons, and the absorption or transfer of the resonance energy of exciting photons before reaching the fluorescing zone [32]. PAHs constitute the dominant organic compound class present in formation water, and thus, their presence in formation water may affect the determination of uranine concentration by means of HPLC with a fluorescent detector, and their influence should be examined in further studies.…”

“…Таким образом, можно сделать вывод, что анализ синхронных спектров с разным сдвигом Δλ позволяет улучшить избирательность (селективность) флуоресцентного метода определения ПАУ в смеси. При этом важно, что для получения синхронных спектров не требуется особого оборудования, они могут быть получены на обычных спектрофлуориметрах, в которых предусмотрено одновременное (синхронное) изменение длин волн монохроматоров возбуждения и регистрации спектров флуоресценции [2].…”

“…Однако обычные классические флуориметрические методы характеризуются ограниченной избирательностью (селективностью). При анализе сложных природных смесей перекрытие широких полос флуоресценции ПАУ при комнатной температуре обычно мешает процессу идентификации отдельных компонентов [2]. В случае сложных проб окружающей среды область применения флуориметрического анализа может быть расширена с помощью синхронной флуоресцентной спектрометрии [3; 4].…”
