A simplified mass screening method for methylmercury exposure was developed using methylmercury-volatilizing bacteria from Minamata Bay. Some bacteria can transform methylmercury into mercury vapor. Most mercury in the hair is methylmercury, which is readily extracted with HCl solution. Black spots are formed on X-ray film due to the reduction of Ag(+) emulsion with mercury vapor produced by me...
An immunoassay that detects mercuric ions in water at concentrations of 0.5 ppb and above is described. The assay utilizes a monoclonal antibody that binds specifically to mercuric ions immobilized in wells of microtiter plates. Within the range of 0.5-10 ppb mercury, the absorbance in the enzyme-linked immunosorbent assay (ELISA) is linear to the log of the mercuric ion concentration. The quan...
a b s t r a c tintroduction: because of more exposure to mercury compounds, the prenatal and postnatal neurotoxic effects of mercury compounds have gained more attention in last decade. the aim of this study was to investigate the effects of mercuric chloride intoxication on spinal cord development during prenatal period. methods: 36 adult sprague-dawley rats after observing vaginal mating plaq...
The standard procedure for the determination of chlorine in organic compounds of mercury consists in decomposition of the material, separation of mercury and determination of chlorine as chloride. Decomposition of the sample could be achieved by wet mineralization [1,2], ignition in a stream of oxygen [3—7] or nitrogen [8], ignition in a flask with oxygen [9], etc. [10, 11]. Chlorine and mercur...
Mercury (II) is a highly toxic metal which induced oxidative stress in the living organism. In the present study we examined the effect of S-Allyl cysteine (SAC) against the mercuric chloride (Hgcl2) intoxicated in albino rat model. The animals were treated with sub-leathal dose of mercuric chloride (1.23 mg/kg body wt) for 7 days. After scheduled treatetment the animals were decapitated and wh...
Mercury pollution threatens the environment and human health across the globe. This neurotoxic substance is encountered in artisanal gold mining, coal combustion, oil and gas refining, waste incineration, chloralkali plant operation, metallurgy, and areas of agriculture in which mercury-rich fungicides are used. Thousands of tonnes of mercury are emitted annually through these activities. With ...
Fly ashes and gypsum are one of the main wastes produced in coal-fired power stations which may be sent to landfills for their disposal. In this work, leaching and speciation of mercury in fly ashes and gypsum from a modern co-combustion power plant equipped with a selective catalytic reduction (SCR) unit in the Netherlands were studied. The mercury leachable contents were checked against diffe...
The reaction of mercury(II) chloride with bis-(pyridin-3-ylmeth-yl)sulfane (L, C12H12N2S) in methanol afforded the title crystalline coordination polymer catena-poly[[di-chlorido-mercury(II)]-μ-bis-(pyridin-3-ylmeth-yl)sulfane-κ2N:N'], [HgCl2L] n . The asymmetric unit consists of one HgII cation, one L ligand and two chloride anions. Each HgII ion is coordinated by two pyridine N atoms from sep...
The metal chloride of LaCl3 was chosen to modify the Au-Cu/AC to decrease the noble metal of gold and enhance the catalytic performances. Then a mercury-free catalyst of Au-Cu-La/AC was prepared by the impregnation method, and the fresh Au-Cu-La/AC and Au-Cu/AC catalysts were also characteri...
Hypertensive Encephalopathy Induced by Mercury Poisoning; a Report of 3 Cases (in an Iranian Family)
M. Sharifian MD1, M. Noorisafa MD 2 , M. Kiahosseini MD3 Abstract: Objective Mercury poisoning is one of the important recent causes of mortality and mortality in children worldwide, particularly in industrial environments; mercury is a poisonous metal, especially harmful to the nervous and immune systems and the kidneys and can even be fatal. Elemental mercury is present in thermometers, barom...
