Resumo: | Passaúna River´s Hidrographic Bay, is used with the purpose of distributing water to approximately five hundred people living at Curitiba and Metropolitan Region. Anthropological activities, such as occupation and usage of soil in an irregular way, throwing non-treated domestic wastewater and the presence of the old controlled landfill called Lamenha Pequena nearby, led to the possibility of existing heavy metals contamination at Passaúna River. The present work had as main target, to analyse the sediments of Passaúna River for the evaluation of impacts caused by heavy metals to the local environment. Samples were collected in two stages: in the first stage, the samples were collected on March,2006 during a raining period and in the second stage, on September,2006 during an intense drought period. Five points were chosen as representative samples throughout Passaúna River, from the old controlled landfill to the entrance of the reservatory. Results revealed that seasonality has a direct influence over the aquatic system, altering mainly the results of granulometry and also the distribution of the elements in the sediment. The X-Ray analysis applied to an enrichment factor, showed that K and Mg concentrations are above the media concentration of such elements on earth´s crust, probably because of their wide application in agriculture sector. Co and Cr were detected and also enriched in point five (reservatory entrance). Ba was found only during the raining period at the downstream point of the old landfill. High concentrations of Pb were detected in all points collected and these concentrations varied between 268mg/kg to 493,5mg/kg, which ilustrates the presence of an anthropological contamination. |

Atividades antropogênicas, tais como o uso e ocupação irregular do solo, lançamento de esgotos não tratados, além presença do antigo Aterro Controlado da Lamenha Pequena, levaram à possibilidade de existência de contaminação por metais pesados no Rio Passaúna. O presente trabalho teve como principal objetivo analisar os sedimentos do Rio Passaúna, para avaliação dos impactos dos metais pesados sobre o ecossistema local. As coletas foram realizadas em duas etapas, a primeira em março de 2006, período chuvoso, e a segunda em setembro de 2006, período de seca intensa, em cinco pontos de amostragem ao longo do leito do Rio Passaúna, desde o antigo Aterro Controlado da Lamenha Pequena até a entrada do reservatório. Os resultados revelaram que a sazonalidade exerce influência direta sobre o sistema aquático, causando alterações principalmente nos resultados de granulometria e distribuição dos elementos no sedimento. As análises realizadas por fluorescência de raio X, aplicadas a um fator de enriquecimento, mostraram que as concentrações de K e Mg encontram-se acima da média encontrada na crosta terrestre, possivelmente pela ampla utilização desses elementos na agricultura, Co e Cr foram encontrados e mostraram-se enriquecidos no ponto 5, localizado na entrada do reservatório, Ba foi encontrado apenas na coleta do período chuvoso no ponto a jusante do aterro desativado. Altas concentrações de Pb foram encontradas em todos os pontos de coleta, variando de 268 mg/kg a 493,5 mg/kg, evidenciando a contaminação antrópica.Universidade PositivoBrasilPós-GraduaçãoPrograma de Pós-Graduação em Gestão AmbientalUPCarvalho Filho, Marco Aurélio S.http://lattes.cnpq.br/3833309149531309Carvalho Neto, Fernando da Silvahttp://lattes.cnpq.br/9437896793528950Bocalon, Tiago Silvestro2021-06-25T18:37:41Z20072021-06-25T18:37:41Z2007info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://repositorio.cruzeirodosul.edu.br/handle/123456789/2324porinfo:eu-repo/semantics/openAccessreponame:Repositório do Centro Universitário Braz Cubasinstname:Centro Universitário Braz Cubas (CUB)instacron:CUB2021-08-04T13:39:00Zoai:repositorio.cruzeirodosul.edu.br:123456789/2324Repositório InstitucionalPUBhttps://repositorio.brazcubas.edu.br/oai/requestbibli@brazcubas.edu.bropendoar:2021-08-04T13:39Repositório do Centro Universitário Braz Cubas - Centro Universitário Braz Cubas (CUB)false |
