Interaction of methylmercury compounds with albumin

Archives of Toxicology, 1990
The nature of interaction between bovine serum albumin (BSA) and methylmercurial compounds has been investigated by ultrafiltration analysis. Four types of BSA samples, mercaptalbumin, its mixed disulfides with glutathione (GSH) and L-cysteine (CySH), and S-carbamidomethylated derivative, were used for binding assays with methylmercury (MM) chloride ...

Biosynthesis of Methylmercury Compounds by the Intestinal Flora of the Rat

Archives of Environmental Health: An International Journal, 1977
The contents of the rat cecum and, to a lesser extent, those of the small intestine, synthesized methylmercury from mercuric chloride labeled with Hg 203 in vitro under aerobic or anaerobic conditions. The rate of formation was approximately 18 ng/g cecal contents/20 hr.

Binding of Methylmercury Compounds by Humic and Fulvic Acids

Water, Air, & Soil Pollution, 1995
Humic and fulvic acids were isolated from Fawn Lake in Ontario and investigated by membrane dialysis for their ability to bind CH3Hg+. By measuring the distribution of methylmercury compounds in and outside of the dialysis membrane, for the first time, binding capacities and conditional stability constants for CH3Hg+ and humic acids could be calculated.

Force constants of methylmercury(II) compounds

Journal of Organometallic Chemistry, 1978
The results of force constant calculations of systems Hg(CH3)X = CH3, Cl, Br, I, CN, SCH3 and {As(CH3)3}+) are briefly reviewed and the importance of data compatibility in comparative studies is stressed. Aspects of relationships between the force constants and other physical properties are discussed, but outside the limited series X = Cl, Br or I do ...

Molecular activation analysis for methylmercury compounds

Journal of the Chemical Society, Chemical Communications, 1974
The use of neutron activation analysis for the selective determination of mercury in various mercury compounds is described as well as the application of this technique to the determination of methylmercury in fish tissue.

Simultaneous determination of inorganic mercury and methylmercury compounds in natural waters

Analytical and Bioanalytical Chemistry, 2002
The purpose of the present work was to develop a simple, rapid, sensitive and accurate method for the simultaneous determination of inorganic mercury (Hg(2+)) and monomethylmercury compounds (MeHg) in natural water samples at the pg L(-1) level. The method is based on the simultaneous extraction of MeHg and Hg(2+)dithizonates into an organic solvent ...

Structure and Dynamics in a Bis(perfluoroalkyl)triazapentadiene Methylmercury Compound

Organometallics, 2004
The compound [Ph2N3C2(C3F7)2]HgCH3 was synthesized from Na[Ph2N3C2(C3F7)2] and CH3HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomers feature a η1-Ph2N3C2(C3F7)2 ligand. In the asymmetrical one, the CH3Hg group is bonded to one of the two terminal nitrogen atoms.

The effects of methylmercury compounds on the skin (in vitro) of the leopard frog (Rana pipiens)

Comparative and General Pharmacology, 1973
Abstract 1. 1. Leopard frogs readily survive injections of large amounts of dimethylmercury or methylmercuric chloride. 2. 2. The short-circuit current and P.D. across the skin ( in vitro ) were not changed by dimethylmercury (10 −3 M ) but were reduced by methylmercuric chloride (10 −4 M ).

Volatilization of mercury compounds by methylmercury-volatilizing bacteria in Minamata Bay sediment

Bulletin of Environmental Contamination and Toxicology, 1988
Minamata Bay has been heavily polluted by high mercury concentrations which gave rise for a long time to methylmercury poisoning, Minamata disease (Kutsuna 1968; Irukayama 1977). The mercury still exists in the sediments of the Bay. The population of mercury-resistant bacteria in the sediments of Minamata Bay is larger than that in the sediments of ...

1H-NMR study of the removal of methylmercury from intact erythrocytes by sulfhydryl compounds

Journal of Inorganic Biochemistry, 1986
The effectiveness of penicillamine, N-acetylpenicillamine, meso-2,3-dimercaptosuccinic acid, 2,3-dimercaptopropanesulfonic acid, and dithioerythritol for removing methylmercury (CH3Hg(II) from intact human erythrocytes has been studied by 1H-nuclear magnetic resonance spectroscopy.
