Soils formed from granites are distributed worldwide, therefore, studies regarding their geochemical signature on tropical soils are important to understand key processes of soil weathering and soil chemistry. This paper reports the effect of S- and I-type granitic rocks on the content and distribution of trace and major elements in soil profiles developed across a climosequence in Northeastern Brazil. In general, soils developed from I-types show greater trace and major element concentrations than ...

South American rattlesnakes are represented in Brazil by a single species, Crotalus durissus, which has public health importance due to the severity of its envenomation and to its wide geographical distribution. The species is subdivided into several subspecies, but the current classification is controversial. In Brazil, the venoms of C. d. terrificus and C. d. collilineatus are used for hyperimmunization of horses for antivenom production, even though the distinction of these two subspecies are ...

An understanding of the stock of soil organic carbon (SOC) in the umbric epipedon of Oxisols located in the tropical forests surrounded by a semi-arid region is limited but essential because of their importance in the global cycle of carbon (C). The purpose of this study was to assess the effects of climatic (temperature and rainfall), soil organic matter (SOM) composition and litter on the stability of C in surfaces and subsurfaces in five Humic Oxisols along a 475-km climosequence from 143 to 963 ...

A thick umbric horizon (~ 1 m) is an important component in the balance of the carbon (C) cycle. However, little is known about the characteristics and C stability in the umbric horizon of Ferralsols, the tropical environments surrounded by semi-arid regions in northeastern (NE) Brazil. This study aimed to evaluate (i) morphological, physical, chemical, biological and mineralogical attributes and (ii) C accumulation in the surface and subsurface within five Umbric Ferralsols along a 475-km climosequence ...

The Brazilian Regulatory Agency for fuel production and commercialization requires that the sodium concentration in alcohol fuel should be determined by flame photometry and that the analytical curves should be obtained with matrix-matched standards. Notwithstanding, this methodology can produce inexact results because alcohol fuel presents a significant variability in matrix composition and, consequently, in the matrix effect. This problem can be circumvented by using the standard addition method ( ...

This study provides new insights into the effects of a parent material on inherent soil fertility. We describe the mineralogy and geochemistry of I- and S-type granites and their effect on soil fertility under similar environmental conditions in Borborema Province, NE Brazil, using standard mineralogical, geochemical and soil analyses as well as multivariate analysis and geographic information system approaches. We hypothesized that soils derived from I-type granites will develop higher natural ...

The Borborema Province in northeast Brazil represents the western portion of the extensive geological Brasiliano-Pan African orogenic system. It is characterized by voluminous granites, which originate from the melting of igneous rocks. We investigated the influence of metaluminous granite mineralogy on the geochemistry of rare earth elements (REEs) in rocks and soils across a climosequence. Mineralogical, petrographic, geochemical, and soil analyses were used to examine the geochemistry of REEs ...

The FI-GSAM system exploits the concentration gradients of the sample and the standard solution, requires only one standard solution per analyte and provides several addition levels using a single simultaneous injection of the sample and of each standard solution. Because ...

Abstract Introduction: Hypertension (systemic arterial hypertension [SAH]) is a systemic condition that affects about 30% of the world population, according to data from the World Health Organization (WHO). Drugs used to control this disease have the potential to induce xerostomia, an oral condition in which the decrease of the salivary flow is observed and whose presence leads to the increase of the index of caries, periodontal disease, loss of the teeth, dysgeusia, difficulty of mastication, dysphagia, ...

Weathering and pedogenesis have been studied for a wide range of rocks and climates around the world. However, the eruption of rhyolitic magmas is a rare geological event, which leads to few studies associated with the rhyolite-soil-landscape relationship. In this context, this study evaluated the influence of rhyolite weathering on the properties of soils along a slope in an Atlantic Forest environment in the state of Pernambuco, northeastern Brazil. Four weathering profiles derived from rhyolites ...

The traditional flow chemiluminescence (CL) systems typically use flow cells in spiral shape mounted in front of a photomultiplier tube (PMT). The sample is transported by using carrier fluids, undergoes dispersion, and mixes with reagents and CL reaction occurs before reaching the flow cell. As a consequence, the maximum of the chemiluminescence intensity is not exploited and the sensitivity is significantly diminished. In this work, these drawbacks were overcome by using a flow–batch approach and ...
