Gilmar W. Siqueira, Fabio Aprile, Georg Irion, Bruce G. Marshall & Elisabete S. Braga · Chemical Science International Journal · 2016

Place and Aims: Total concentrations of Hg and geochemical analysis of sediments from the Amazon Continental Shelf (47º52'W-4º19'N, 51º04'W-2º16'S) were determined in 25 sampling sites, during the months of lowest flow of the Amazon River. The aim of this study was to determine t...

Sedimentary Transport Influences on Diagenetic Processes at the Amazon Continental Shelf, Brazil

Fabio Aprile, Gilmar W. Siqueira, Assad Darwich & Georg Irion · Journal of Geography, Environment and Earth Science International · 2019

This research aimed to correlate the sedimentary transport with the diagenetic processes in the coastal zone and Amazon Continental Shelf (ACS). Physical and physical-chemical parameters, trace element contents (Cr, Pb, Ni, Zn and Hg), and O2, CO2 and iron flux were determined in...

Trace-elements Behavior in the Sedimentary Transport Regime of the Blue Amazon, Brazil

Gilmar W. Siqueira, Fabio Aprile, Assad Darwich & Georg Irion · International Journal of Environment and Climate Change · 2018

Trace elements or trace metals are of great interest in environmental studies due to their toxic and cumulative properties in the biological and sedimentary compartments. The discharge area of the Amazon River mouth receives an immense volume of suspended material with adsorbed t...
