Fluorescence Excitation–Emission Matrices (EEMs) were obtained from samples only filtered (0.45 μm) and diluted, if necessary, to avoid the inner filter effect. In addition, physicochemical parameters were measured to know the quality of the water and the effluents. Results show that EEMs allow a rapid and simple control of the effluents from fisheries and domestic sewage in Chubut River estuary, necessary to take management decisions.application/pdf6909–6919engopenAccessChubut RiverDissolved Organic MatterExcitation–emission MatricesChemometric AnalysisUniversidad Nacional de RosarioSpringerUniversidad Nacional de la Patagonia San Juan BoscoChiarandini Fiore, Jessica PaolaScapini, María del CarmenOlivieri, Alejandro CésarEsta es una versión posterior a la revisión por pares y anterior a la publicación, de un artículo publicado en Environmental Monitoring and Assessment.
