Chronopotentiometric stripping analysis using gold electrodes, an efficient technique for mercury quantification in natural waters
(Wiley-Blackwell, 2005-05-01)
This paper proposes a simple methodology for mercury quantification in natural water by stripping chronopotentiometry at constant current, using gold (film) electrodes constructed from recordable CDs in stationary cell. ...
Hematological changes and cytogenotoxicity in the tilapia Oreochromis niloticus caused by sub-chronic exposures to mercury and selenium
(Springer, 2015-02-01)
Fish bioassays are valuable tools that can be used to elucidate the toxicological potential of numerous substances that are present in the aquatic environment. In this study, we assessed the antagonistic action of selenium ...
Characterization of molecular biomarkers of mercury exposure to muscle tissue of Plagioscion squamosissimus and Colossoma macropomum from the Amazon region
(2019-03-15)
Mercury has the ability to bind to a variety of biomolecules, which can compromise its structure and functionality and thus promote its toxic effects. The aim of this study is to identify possible mercury biomarkers in ...
Identification of protein biomarkers of mercury toxicity in fish
(2017-12-01)
Bioaccumulative metals such as mercury are found in increasing amounts in fish and their consumers. In the region of the Madeira River, in the Brazilian Amazon, mercury (Hg) is a predominant contaminant in the aquatic ...

Selective sorption of mercury(II) from aqueous solution with an organically modified clay and its electroanalytical application
(Taylor & Francis Inc, 2006-01-01)
The organo-clay used in this work was prepared from a Na-montmorillonite (Wyoming-USA deposit) by treatment with water solution of hexadecyltrimethylammonium cations. As organo-clays exhibit strong sorptive capabilities ...
Reduction of mercury(II) by tropical river humic substances (Rio Negro) - A possible process of the mercury cycle in Brazil
(Elsevier B.V., 2000-12-04)
The evolution of elemental Hg from its environmental compounds has already been supposed to be an important process within the global mercury cycle. The present study characterizes the abiotic reduction of Hg(II) ions by ...
