Resumo: | Effects of urban drainage on the physico-chemical and biological characteristics of surface water in Conceição Lagoon (Florianópolis, SC, Brazil). The proximal and distal surface waters from the drainageoutlets in Lagoa da Conceição – Conceição Lagoon – (27º34’S e 48º27’W) were sampled and characterized according to their physico-chemical and biological characteristics between April 2001 and March 2002. It wasfound that urban and pluvial drainage influenced the characteristics of the water column of the lagoon in relation to silicate and dissolved nitrogen. Through the dynamics of biogeochemistry, phosphorus was excludedfrom the dissolved form, and no expressive differences between the studied areas were observed. Also, the particulate matter did not present any alterations directly determined by the drainage into the lagoon, whichcould be considered as punctual at the surface water. The physical dilution process was significative for the differences of the concentrations of silicate and nitrate between areas that were proximal and distal from the drainage. |

A drenagem urbana e pluvial influenciou as características da coluna de água da Lagoa da Conceição em relação ao silicato e aos nitrogenados dissolvidos. O fósforo foi retirado da forma dissolvida através da dinâmica biogeoquímica, não apresentando diferenças significativas entre as áreas estudadas. O material particulado também não apresentou alterações determinadas diretamente pela urbanização na laguna. O efeito desta pôde ser considerado pontual na água de superfície da laguna, sendo que o processo físico de diluição foi significativo para as diferenças das concentrações de silicato e de nitrato entre as áreas com maior e menor influência da drenagem urbana.Universidade Federal de Santa Catarina2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21181Biotemas; v. 19 n. 2 (2006); 7-162175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21181/19161Copyright (c) 2006 Alessandra Fonsecahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFonseca, Alessandra2022-11-21T11:40:58Zoai:periodicos.ufsc.br:article/21181Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:40:58Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
