Contamination of water bodies in areas of high population density is a major problem in many localities, especially in developing countries. Many analytical techniques can be used in combination to monitor the condition of these water bodies. Among them are the techniques of molecular fluorescence spectroscopy, which can be very useful in assessing the organic matter in aquatic environments. There are several ways to obtain fluorescence spectroscopic data; one of the most comprehensive is the use of excitation-emission matrices. In our study, a campaign in August 2010 was made to assess the contamination of some tributaries of the Upper Iguaçu basin - Curitiba Metropolitan Region - using excitation-emission matrices to assess the dissolved organic matter Almost all the rivers analyzed showed signs of contamination, mainly suggested by the presence of a fluorescence peak associated with protein and a high intensity in the region similar to fulvic acids.
