Simultaneous determination of inorganic mercury and methylmercury compounds in natural waters
Analytical and Bioanalytical Chemistry, 2002The 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, 2004The 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.

Volatilization of mercury compounds by methylmercury-volatilizing bacteria in Minamata Bay sediment
Bulletin of Environmental Contamination and Toxicology, 1988Minamata 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 ...

Regeneration in two freshwater planarian species exposed to methylmercury compounds
Russian Journal of Developmental Biology, 2008The regeneration rate was studied by the morphometric method in planarians Polycelis tenuis and Dugesia lugubris after different periods of exposure on food substrates with high (0.30-0.50 mg/kg wet weight) and low (0.02-0.07 mg/kg) concentration of methylmercury compounds.

1H-NMR study of the removal of methylmercury from intact erythrocytes by sulfhydryl compounds
Journal of Inorganic Biochemistry, 1986The 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.

AbstractThe reactions of MeHgX (X: ‐OH, ‐NO3, ‐ClO4) with adenine in H2O/EtOH mixtures in different stoichiometric ratios give the compounds (I)‐(III) in a yield of about 60%.

Beans, cabbage, carrots, millet, onions, potatoes, and tomatoes were grown on silt loam, gravelly loam, and muck soils treated with 1 and 10 ppm of mercuric chloride, methylmercury dicyandiamide (PAN), or phenylmercuric acetate. Appreciable concentrations of methylmercury were present only in PAN-treated soils and in beans, millet and tomatoes grown on
