• Abstract

  The wetlands have a fundamental role in the control of factors that can affect or be affected by the climatic and environment changes. The project will be developed in Nhecolândia (South Mato Grosso State), a region characterized by a system of lakes, with water composition varying from fresh to hyper saline. It is concerned to a multi and interdisciplinary research whose scientific chall…

• Abstract

  The Minamata convention, a global agreement that aims to provide reduction of uses and emissions of mercury (Hg), has been signed in 2013 by 128 countries of the United Nations, among them, Brazil. Both atmospheric concentrations of Hg and its speciation can be used as indicators of emission sources. Furthermore, concentrations of Hg in rainwater allow to quantify the local/regional depos…

  Results obtained in the thematic project FAPESP 2016/14227-5 demonstrated that: 1) the waters of the alkaline lakes of the Pantanal of Nhecolândia systematically present high concentrations of dissolved As (up to 3000 µg L-1); 2) despite the extreme conditions, these lakes are home to an abundant microbial community; 3) higher dissolved As concentrations are generally found in lakes where…

  Speciation, bioaccumulation and biotransformation of arsenic by cyanobacteria (Arthrospira sp. and Anabaenopsis sp.) from the saline-alkaline lakes of the Pantanal of Nhecolândia, BP.MS

• Abstract

  High concentrations of Arsenic (As) were found in the waters of the alkaline lakes of the São Roque farm (Pantanal of Nhecolandia) collected during the dry season in October 2017 and September 2018. However, the concentrations of this element in the samples collected in 2017 were 9 to 49 higher than in the samples collected in 2018. These differences were attributed to the variation of th…

  Influence of hydrological conditions on the availability of arsenic in alkaline lakes of the Pantanal of Nhecolândia, BP.IC

• Abstract

  Arsenic (As) is an abundant metal in the earth's crust, occurring in various environmental compartments, as well it can be available by anthropogenic activities. In the last years, high concentrations of arsenic (up to 4 mg L-1) were detected in saline-alkaline lakes from Nhecolândia, located in Pantanal wetlands. This region is characterized by a rich biodiversity, and by the occurrence …

• Abstract

  Results obtained in the thematic project FAPESP 2016/14227-5 showed that: 1) the waters of the alkaline lakes of the Pantanal of Nhecolândia systematically present high concentrations of dissolved As (up to 3000 µg L-1); 2) Higher concentrations of dissolved As are generally found in lakes where the highest autotrophic activity occurs (green lakes) and which consequently have higher produ…

  Interactions between arsenic species and natural organic matter of the saline-alkaline lakes of the Pantanal of Nhecolândia, BE.EP.MS

• Abstract

  Phosphorus (P) is essential to assure world food security since it cannot be replaced for other elements as a fertilizer in agriculture. The estimations on the amount of remaining phosphate in the world are conflicting. Recycling P from urban waste shows up as an alternative to the dependence of P from the external market. Struvite is the most recovered P product with similar fertilizer p…
