- Mass balance of nutrients during the filling phase of two reservoirs of Sistema Produtor Alto Tietê (SPAT) Valéria Cope Cacilda Thais Janson Mercante Clovis Ferreira do Carmo Suzana Sendacz Adalberto José Monteiro Júnior Biología nitrogen phosphorus Water supply Paraitinga and Biritiba reservoirs are part of Sistema Produtor Alto Tietê andthey play an important role at the public water supply. The purpose of this study is to understand the mass balance of nitrogen and phosphorus that can influence the eutrophication process in reservoirs during the filling phase, and provide information for the implementation of mechanisms to manage water quality. Water samples were collected from August 2005 until May 2006. Concentrations of total phosphorus (PT) and total nitrogen (NT) were measured and the mass balance and loads were estimated. Paraitinga reservoir presented retention of NT and PT during the dry season and export during the rainy season; whilst at Biritiba reservoir we evidenced retention of NT and PT for both dry and rainy seasons. The annual balance demonstrated that during the reservoirs filling process, the systems retain NT and PT. The retention of nutrients into the system indicates that the environments have been modified leading to eutrophication and its consequences, and that it is necessary to outline strategies in order to mitigate the problem and suggest implementation of techniques to reduce the diffuse load. 2011 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187118574007 en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
