Synchronous fluorescence spectroscopy for the study of dissolved organic matter (DOM) in marine lagoon waters (Sacca di Goro, Po delta) showed, using the positions of the excitation/emission peaks, a diagnostic ability to monitor possible pollutants, and the products of fluorescent algal exudation as well as those of the algal decay. A further characterisation of the DOM in the Sacca di Goro was obtained using peak to height ratio 275 nm(hA)/345 nm(hB): high values indicate the presence of the exudates produced by the growing autochthonous marine algal population, while the low values indicate the presence of organic substances of riverine origin (Po di Volano).
