Top down arsenic uncertainty measurement in water and sediments from Guarapiranga dam (Brazil)
2018 - FAUSTINO, M.G.; LANGE, C.N.; MONTEIRO, L.R.; FURUSAWA, H.A.; MARQUES, J.R.; STELLATO, T.B.; SOARES, S.M.V.; SILVA, T.B.S.C. da; SILVA, D.B. da; COTRIM, M.E.B.; PIRES, M.A.F.
Total arsenic measurements assessment regarding legal threshold demands more than average and standard deviation approach. In this way, analytical measurement uncertainty evaluation was conducted in order to comply with legal requirements and to allow the balance of arsenic in both water and sediment compartments. A top-down approach for measurement uncertainties was applied to evaluate arsenic concentrations in water and sediments from Guarapiranga dam (São Paulo, Brazil). Laboratory quality control and arsenic interlaboratory tests data were used in this approach to estimate the uncertainties associated with the methodology.
Guarapiranga dam (São Paulo-SP/Brazil) nitrogen distribution
2017 - SILVA, D.B.; SILVA, T.B.S.C.; MONTEIRO, L.R.; FAUSTINO, M.G.; MARQUES, J.R.; STELLATO, T.B.; SOARES, S.M.V.; PIRES, M.A.F.; COTRIM, M.E.B.
Nowadays Guarapiranga Dam is responsible for about 20% of Metropolitan Region of São Paulo (RMSP) water supply. However, since the 60s an irregular and disordered occupation appears in the area. From the 70’s, the reservoir was reported eutrophic due to untreated urban sewage. Cyanobacteria blooms were frequent since 1990. Nitrogen species are a significant part of this eutrophication problem. In this scenario, the present work presents the distributions of nitrogen species in the Guarapiranga Dam, to compare with other lakes and reservoirs status in the world and to find options to this nutrient management in Guarapiranga Reservoir.
