Metalloproteomic approach of mercury-binding proteins in liver and kidney tissues of Plagioscion squamosissimus (corvina) and Colossoma macropomum (tambaqui) from Amazon region: Possible identification of mercury contamination biomarkers
(2020-04-01)
Fish is an important source of protein, vitamins, and minerals. However, this food is also a major source of human exposure to toxic contaminants such as mercury. Thus, this paper aimed to evaluate mercury-binding proteins ...
Solid-state reactions of mercury with pure noble metals - Part 2. Mercury-iridium system
(Springer, 2002-01-01)
Thermogravimetry, cyclic voltammetry and other analytical techniques were used to study the reactions of mercury with pure iridium. The results allowed to suggest when subjected to heat or anodic stripping voltammetry an ...

Identification of Biomarkers of Mercury Contamination in Brachyplatystoma filamentosum of the Madeira River, Brazil, Using Metalloproteomic Strategies
(2018-05-08)
Predator fish can accumulate high levels of mercury, which qualifies them as potential indicators of this toxic metal. The predatory species Brachyplatystoma filamentosum, popularly known as filhote, is among the most ...
Towards the abatement of environmental mercury pollution: An electrochemical characterization
(Elsevier B.V., 2006-03-15)
Electrochemical experiments in acetic acid-acetate buffer (pH 4.5) are conducted in order to understand metallic and ionic mercury adsorption processes on the pyrite surface. The nature as well as the extent of the spontaneous ...
Metalloproteomic Strategies for Identifying Proteins as Biomarkers of Mercury Exposure in Serrasalmus rhombeus from the Amazon Region
(2020-01-01)
This manuscript describes the results of a metalloproteomic study of mercury in samples of muscle and liver tissue of the species Serrasalmus rhombeus, popularly known as black piranha and characterised as the most voracious ...
Seasonal behavior of mercury species in waters and sediments from the Negro River Basin, Amazon, Brazil
(2007-06-14)
Total (HgT), reactive (HgR) and organic (Hg ORG) mercury species have been quantified in non-filtered waters collected from the Negro River Basin, Amazon (from January/2002 through January/2004), in both black and white ...
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 ...
Investigation of Protein Biomarkers and Oxidative Stress in Pinirampus pirinampu Exposed to Mercury Species from the Madeira River, Amazon-Brazil
(2022-04-01)
In recent decades, the scientific community has widely debated the contamination of fish in the Amazon region by mercury species. As the diet of riverside populations in the Amazon region is based mainly on fish, these ...
