Compound specific stable isotope determination of methylmercury in contaminated soil

Science of The Total Environment, 2018
Rice is one of the main sources of methylmercury (MeHg) to humans, and soil is the main source of MeHg to rice grains. Determining the Hg isotope composition in environmental samples is a good way of characterizing sources of Hg pollution and investigating environmental processes.

Toxicity of methylmercury in aquatic organisms and interaction with environmental factors and coexisting pollutants: A review.

Science of the Total Environment
Mercury is a hazardous heavy metal that is distributed worldwide in aquatic ecosystems. Methylmercury (MeHg) poses significant toxicity risks to aquatic organisms, primarily through bioaccumulation and biomagnification, due to its strong affinity for ...

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.

Binding of methylmercury to humic acids (HA): Influence of solar radiation and sulfide addition reaction of HA.

Science of the Total Environment, 2022
Methylmercury (MeHg) is a neurotoxin that bioaccumulates in organisms and it forms strong complexes with reduced sulfur-containing ligands in dissolved organic matter (DOM).

Role of light in methylmercury photodegradation: From irradiation to absorption in the presence of organic ligands.

Science of the Total Environment, 2022
Photochemical degradation acts as the principal sink for methylmercury (MeHg) in surface water, which is regulated by light and solution matrix (especially the presence of dissolved organic matter, DOM).

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 ...

Mercury (Hg) and methylmercury (MeHg) in sediment and biota: A case study in a lagoon in Central Italy.

Marine Pollution Bulletin, 2022
A quantification of total mercury (Hgtot) and methylmercury (MeHg) concentrations in sediment and mussels was carried out in the east basin of the Orbetello lagoon in order to assess their bioaccumulation potential.

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.
