Última Reference Values of Soil Quality for the Rio Doce Basin Rev. Bras. Ciênc. Solo Guevara,Yang Zumbo Coronel; Souza,José João Lelis Leal de; Veloso,Gustavo Vieira; Veloso,Renato Welmer; Rocha,Pablo Azevedo; Abrahão,Walter Antônio Pereira; Fernandes Filho,Elpídio Inácio. ABSTRACT: The great geological and soil variation in the state of Minas Gerais, Brazil, indicates the need for regional studies to understand the geochemical background of soils. The Rio Doce Basin became a priority area for geochemical background determination after the rupture of the tailings dam of Fundão in 2015. In this context, the objectives of this study were to propose Reference Values of Soil Quality in the Rio Doce Basin, to define variables that can predict metal(loid) concentrations in the soil, and to examine the correlation between metal(loid) concentrations determined by X-ray fluorescence and by the traditional method. One hundred and seven samples were collected from minimally disturbed areas, representing the main soils and source...

Solo Souza,José João Lelis Leal de; Fontes,Maurício Paulo Ferreira; Gilkes,Robert; Costa,Liovando Marciano da; Oliveira,Teogenes Senna de. ABSTRACT: Evaluating soil geochemical diversity in the Amazon Basin has been a challenge largely because most study sites have been at the edge of the basin and it is difficult to get samples in such a region. Here we show that even among the most weathered soils, physicochemical soil properties express lithology. Our results are based on topsoil samples collected from different locations in minimally disturbed areas in the state of Amazonas, Brazil. Soil properties were measured using methods which are suitable for highly developed soils. The Chemical Index Alteration and Weathering Index of Parker was calculated based on the content of metal(loid)s in soils determined by X-ray fluorescence. Descriptive statistics, Pearson correlation, and Principal... Tipo: Info:eu-repo/semantics/article Palavras-chave: Heavy metals; Principal component analysis; XRF; Rainforest soils.
