The article presents information on the challenges and progress in the analysis of polycyclic aromatic compounds (PAC). Ambiguities arise mainly because of the isomeric form and similarity of derivatives of PAC, which makes separation very difficult, and partly because of their similar spectroscopic and chemical properties. Because the fluorescence spectra of PAC are usually broad and overlapping, individual PAC present in their mixtures is estimated by applying chemometric techniques. One major challenge of PAC analysis using fluorescence methods is the non-availability of all the standard compounds and their standard fluorescence spectra.
