Neurological and neuropsychological deterioration in artisanal gold miners from the town of Andacollo, Chile
It is widely known that human exposure to mercury vapor can cause neurological and neuropsychological deterioration. We have investigated if a population of Chilean artisanal gold-mining workers heavily exposed to elemental ...
Methylmercury and inorganic mercury determination in blood by using liquid chromatography with inductively coupled plasma mass spectrometry and a fast sample preparation procedure
(ELSEVIER SCIENCE BV, 2010)
Despite the necessity to differentiate chemical species of mercury in clinical specimens, there area limited number of methods for this purpose. Then, this paper describes a simple method for the determination of methylmercury ...
Hematological changes and cytogenotoxicity in the tilapia Oreochromis niloticus caused by sub-chronic exposures to mercury and selenium
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 ...
Benthic fish blood as a biomarker for recent exposure to mercury
(Asoc Espan Limnol-mislata, 2018-01-01)
This study evaluated the concentration of Hg in the blood of the benthic fish species Geophagus brasiliensis captured from the Rio Grande and Billings Reservoir, which is located along the Upper Tiete River Basin (Sao ...
Abnormal antioxidant system in erythrocytes of mercury-exposed workers
(Stockton PressBasingstokeInglaterra, 1998)
Slurry sampling in serum blood for mercury determination by CV-AFS
(Elsevier Science, 2009-01)
The heavy metal mercury (Hg) is a neurotoxin known to have a serious health impact even at relatively low concentrations. A slurry method was developed for the sensitive and precise determination of mercury in human serum ...
Effects of mercury on the arterial blood pressure of anesthetized rats
The available data suggests that hypotension caused by Hg2+ administration may be produced by a reduction of cardiac contractility or by cholinergic mechanisms. The hemodynamic effects of an intravenous injection of HgCl2 ...
Prevenção dos efeitos tóxicos do cloreto de mercúrio em ratos jovens pelo cloreto de zinco: papel das metalotioneínas
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2006-10-31)
Zinc, cadmium, and mercury are divalent metals and constitute same group of the periodic table. While zinc is an essential metal, the others are toxic metals. The most important common feature among these metals is the ...
Functional consequences of lead and mercury exposomes in the heart
Lead and mercury are heavy metals that are highly toxic to life forms. There are no known physiological processes that require them, and they do not have a particular threshold concentration to produce biologic damage. ...
