Environmental assessment of mercury pollution in urban tailings from gold mining
(Elsevier Inc., 2013)
It is well-known that small-scale artisanal mining is a source of mercury emissions into the environment, mainly from the use of rudimentary technologies that use mercury amalgamation in the extraction process. Mines near ...
Flow-through polarographic cell for flow-injection analysis. Determination of nifedipine in pharmaceutical formulations
(JOHN WILEY & SONS INC, 1997)
A simple design of a polarographic flow-through cell is proposed in which a conventional dropping mercury electrode (DME) is used as working electrode, and a mercury pool and a platinum wire are used as the reference and ...
Widespread microbial mercury methylation genes in the global ocean
(Wiley, 2020)
Methylmercury is a neurotoxin that bioaccumulates from seawater to high concentrations in marine fish, putting human and ecosystem health at risk. High methylmercury levels have been found in the oxic subsurface waters of ...
Mercury in a marine trophic chain
(SPRINGER-VERLAG, 2002-03)
The mud of the northern zone of the Gulf of Arauco is considered an area of sediments rich in organic matter, due to the current regime and to the geomorphology of the gulf. The possible accumulation of heavy metals derived ...
A selective fluorescent probe for the detection of mercury (II) in aqueous media and its applications in living cells
(2012)
In this Letter we present a new probe, 2-amino-3-hydroxy-2-(hydroxymethyl) propyl 2-(7-hydroxy-2-oxo-2H-chromen-4-yl)acetate (PMR), which can reversibly detect mercuric ions (Hg 2+) in HEPES buffer under physiological ...
Toxic Pigment in a Capacocha Burial: Instrumental Identification of Cinnabar in Inca Human Remains from Iquique, Chile
(Blackwell Publishing Ltd, 2018)
© 2018 University of Oxford We report on the analysis of a red pigment found in a lavish Inca burial from Cerro Esmeralda, Chile, associated with the human sacrifice of two young girls. The outcome shows that the red pigment ...
Mercury in fish and its importance in health Mercurio en pescados y su importancia en la salud
(Sociedad Medica de Santiago, 2014)
© 2014, Sociedad Medica de Santiago. All rights reserved.The contamination of fish with methylmercury (MeHg) could hamper the health promoting properties of fish. Currently, there is strong evidence about the health benefits ...
Physical characterization of fault rocks within the Opalinus Clay formation
(Nature, 2022)
Near-surface disposal of radioactive waste in shales is a promising option to safeguard the population and environment. However, natural faults intersecting these geological formations can potentially affect the long-term ...
Electrochemical study, on mercury, of a Meta-nitroarylamine derivative of nor-β-lapachone, an antitumor and trypanocidal compound
(2010)
The electrochemistry of 2,2-dimethyl-(3H)-3-(N-3'-nitrophenylamino) naphtho[1,2-b]furan-4,5-dione ([Q]-PhNO2), on mercury was investigated. The first peak is consistent with a quasi-reversible one-electron reduction of the ...
High status of mercury and selenium in false killer whales (Pseudorca crassidens, Owen 1846) stranded on Southern South America: a possible toxicological concern?
(Elsevier, 2018)
The study was carried out to determine Hg and Se concentrations in false killer whales stranded on the Estrecho de Magallanes, Chile, South America. Tissue samples of five mature specimens were analyzed (two females and ...
