Resumo: The aim of the study was to evaluate quantitative physical-chemical parameters of water from streams in the Tarumã microbasin (MS, Brazil), to quantify metals (Cd, Pb, Cr, Cu, Fe, Zn and Ni) in the bottom sediments of these streams and to evaluate quali-quantitatively the vegetation index of normalized difference of locations (NDVI) by means of satellite images.Water turbidity and electrical conductivity values were highest at the nearest points in the urban region. In the NDVI analysis, sites P1, P2 and P4 presented reduced local ciliary vegetation, classified as low or very low. At sites P3, P5 and P6 we found higher proportions of vegetation at moderate and low levels. Regarding metals in sediments, all sampled sites presented metal concentrations below the limits established by current legislation. The low rate of vegetation cover around streams in the Tarumã microbasin, especially in spring sites, may compromise the equilibrium of this system.

Los valores de turbidez y conductividad eléctrica del agua fueron más altos en los puntos más cercanos a la región urbana. En el análisis NDVI, los puntos P1, P2 y P4 mostraron una vegetación ribereña local reducida, clasificada como baja o muy baja. En los lugares P3, P5 y P6 encontramos mayores proporciones de vegetación a niveles moderados y bajos. Con respecto a los metales en los sedimentos, todos los puntos muestreados tenían concentraciones de metales por debajo de los límites establecidos por la legislación vigente. La baja tasa de cobertura vegetal alrededor de los arroyos en la microcuenca Tarumã, especialmente en los manantiales, puede comprometer el equilibrio de este sistema.O objetivo do estudo foi avaliar parâmetros físico-químicos quantitativos da água proveniente de córregos na microbacia Tarumã (MS, Brasil), quantificar metais (Cd, Pb, Cr, Cu, Fe, Zn e Ni) nos sedimentos de fundo desses córregos e avaliar quali-quantitativamente o índice de vegetação de diferença normalizado dos locais (NDVI) por meio de imagens de satélite. Os valores de turbidez e condutividade elétrica da água estavam mais altos nos pontos mais próximos da região urbana. Na análise do NDVI, os pontos P1, P2 e P4 apresentaram a vegetação ciliar local reduzida, classificada em baixo ou muito baixo. Nos locais P3, P5 e P6 constatamos maiores proporções de vegetação em níveis moderado e baixo. Em relação aos metais nos sedimentos, todos os pontos amostrados apresentaram concentrações de metais abaixo dos limites estabelecidos pela legislação vigente. O baixo índice de cobertura vegetal em torno dos córregos na Microbacia Tarumã, principalmente nos locais de nascentes, pode comprometer o equilíbrio desse sistema.Research, Society and Development2020-06-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/486210.33448/rsd-v9i7.4862Research, Society and Development; Vol. 9 No. 7; e806974862Research, Society and Development; Vol. 9 Núm. 7; e806974862Research, Society and Development; v. 9 n. 7; e8069748622525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4862/4230Copyright (c) 2020 Lucilene Finoto Viana, Luiza Flavia Veiga Francisco, Julio César Jut Solórzano, Claudia Andrea Lima Cardoso, Sidnei Eduardo Lima-Juniorinfo:eu-repo/semantics/openAccessViana, Lucilene FinotoFrancisco, Luiza Flavia VeigaCardoso, Claudia Andrea LimaSolórzano, Julio César JutLima-Junior, Sidnei Eduardo2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4862Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:34.725718Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
