Avaliação Da Contaminação Por Cobre E Chumbo Do Lago Aratimbó - Umuarama - Pr

Abstract: Este trabalho teve como objetivo quantificar os metais Cobre e Chumbo presentes na água e no sedimento do lago Aratimbó, localizado na cidade de Umuarama-PR e analisar os indicadores abióticos de temperatura e pH da água. As coletas foram feitas em triplicatas, em três pontos distintos, em dois diferentes dias, sendo o primeiro em tempo seco, anterior a chuva e outro logo após a primeira chuva. As amostras tiveram sua temperatura e  pH verificado in locu e a determinação dos metais ocorreu através de Espectrof… Show more

“…For Esteves (2011), the increase in temperature in water bodies leads to the intensification of decomposition of OM, since there is a transfer of heat from the surface to the hypolimnion, driving the death of aquatic organisms and, consequently, increasing the amount of OM. From data released by the Environmental Company of the State of São Paulo (CETESB, 2019) for the Trophic State Index (TSI), an increase in the trophic state was observed between the year of study by until 2018, the latest data available until now. Between the years 2010 to 2018, the TSI evolved negatively from ultraoligotrophic to mesotrophic.…”
