MORTATTI, Jefferson; VENDRAMINI, Diego  and  OLIVEIRA, Helder de. Evaluation of fluvial domestic pollution in the urban area of Piracicaba, SP, Brazil. Rev. Ambient. Água [online]. 2012, vol.7, n.2, pp.110-119. ISSN 1980-993X.

The influence of urban raw sewage, in terms of per capita load pollution of major dissolved inorganic chemical species, in fluvial dissolved load was estimated using a model of punctual sewage contributions without previous treatment, in urban central area of Piracicaba city, SP. The inorganic loads represented by major cations, anions and dissolved silica, were determined in both raw sewage and in the river, before and after the river crossing the urban area. This model also allowed the contributions of these chemical species of total effluent loads to be estimated for the entire drainage basin, as well their respective contributions per capita.

Keywords : raw sewage; dissolved load; pollution; Piracicaba river.
