Risks of using EDTA as an agent for trace metals dosing in anaerobic digestion of olive mill solid waste
(TAYLOR & FRANCIS LTD, 2017)
Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil
(SPRINGER, 2009)
In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation ...
Trace metal concentrations in Spartina densiflora and associated soil from a Patagonian salt marsh
(Elsevier, 2014-10-28)
The objectives of this study were to (i) assess in situ trace metal concentrations in soil and in Spartina densiflora in a Patagonian salt marsh (Rawson, Chubut, Argentina) and (ii) investigate the relationship between ...
Towards field trace metal speciation using electroanalytical techniques and tangential ultrafiltration
(2016-05-15)
In this work we propose a trace metal speciation methodology to determine the total, free and ultrafiltered (<1 KDa) metal fractions using electrochemical methods (SCP and AGNES) and tangential ultrafiltration (UF) experiments ...
TRACE METAL THERMODYNAMIC SPECIATION WITH HUMIC SUBSTANCES: THE NICA-DONNAN MODEL
(Soc Brasileira Quimica, 2017-10-01)
This work presents a critical overview of the NICA-Donnan model for trace metal thermodynamic speciation with humic substances obtained from natural organic matter in soils, natural waters and anthropogenic sources. A first ...
Trace metal concentrations in the hair of Zalophus californianus pups and their relation to feeding habits
(Biological Trace Element Research, 2008)
The levels of six trace metals (Hg, Se, Pb, Cu, Fe, and Zn) were measured in the hair of California sea lion pups from eight rookeries in the Gulf of California, with the aim of relating these levels with the animals feeding ...
Bioaccumulation of some trace elements in the biota of the hydrothermal fields of the Guaymas Basin (Gulf of California)
(Boletín de la Sociedad Geológica Mexicana, 2009)
Data from the hydrothermally influenced Guaymas Basin of the Gulf of California are presented on the concentration and distribution of Ag, As, Au, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, Sb, Se, and Zn in different tissues of ...
Bioavailability of trace metals and rare earth elements (REE) from the tropical soils of a coal mining area
(Elsevier B.V., 2020-05-15)
In order to assess the environmental risks related to mining activities in Southern Brazil, the transfer of trace metals and rare earth elements (REE) from soils to soybeans was evaluated in a U-rich area associated with ...
