Amazon River dissolved load: temporal dynamics and annual budget from the Andes to the ocean
(Springer Verlag, 2016-06)
The aim of the present study is to estimate the export fluxes of major dissolved species at the scale of the Amazon basin, to identify the main parameters controlling their spatial distribution and to identify the role of ...
CO2 emissions from a municipal site for final disposal of solid waste in Gualeguaychu, Entre Rios Province, Argentina
(Springer, 2011-08)
This paper estimates CO2 fluxes in a municipal site for final disposal of solid waste, located in Gualeguaychu, Argentina. Estimations were made using the accumulation chamber methods, which had been calibrated previously ...
Amino acid biogeochemistry in the Laurentian Trough: vertical fluxes and individual reactivity during early diagenesis
(1998)
The detailed composition of total hydrolysable (THAA), dissolved free (DFAA) and combined (DCAA) amino acids was studied in settling particles and the solid phase and porewaters of underlying sediments in the Laurentian ...
Temporal variability and annual budget of inorganic dissolved matter in Andean Pacific Rivers located along a climate gradient from northern Ecuador to southern Peru
(Elsevier, 2018)
In Ecuador and Peru, geochemical information from Pacific coastal rivers is limited and scarce. Here, we present an unedited database of major element concentrations from five HYBAM observatory stations monitored monthly ...

Weathering processes and natural radionuclides
(2011-12-01)
In managing our hydrological systems, increasing use is being made of information generated from studies held for understanding the controls on chemical weathering due to its importance in affecting the evolution of the ...
Anthropogenic influences on annual flux of cations and anions at meio stream basin, São Paulo State, Brazil
(Springer, 2010-01-01)
The chemical dynamics at Meio Stream Basin, So Paulo State, Brazil were evaluated using major elements as natural tracers. The surface water samples from Meio Stream were collected near the mouth of Meio Stream at the ...

Análise química de materiais cerâmicos : digestão por fusão e medidas por ICP OES com configuração axial
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2007-10-26)
Ceramic samples are efficiently digested using fusion procedures. However the elevated amounts of dissolved solids in the resulting solutions may cause spectral and transport
interferences, affect the analytical blanks ...
Human influences on the present denudation rates of the Paulista Peripheral Depression, Brazil
(2020-02-15)
Chemical weathering and soil erosion in large or small watersheds are used to understand the effect of evolution processes on the Earth's surface and climate. Currently, human-driven land use changes have substantial effects ...
