Análise de fluorescência de substâncias húmicas extraídas da água, solo e sedimento da Lagoa dos Patos - MS
The humic substances were extracted from sediments, water and soil close to the Lagoa dos Patos-MS. The characterization was performed through fluorescence emission. In the HSs it is possible to see strong indications of incorporation of compounds originating from lignin degradation, confirmed by fluorescence emission (EEM and synchronous spectra). These differences observed in HSs may be due to tropical regions displaying a great variety of vascular plants and aquatic macrophytes that contribute natural organic matter. The seasonality effect also causes the entrance of pedogenic material and the suspension of sediments by the action of winds.
