On the Tris-methylmercury-oxonium Compounds

Croatica Chemica Acta, 1957
The preparation and properties of tris-methylmercury-oxonium fluoborate (CH3Hg)3OBF4 are described. A method for the preparation of methylmercury oxide (CH3Hg)2O by dehydration of methylmercury hydroxide is given. The crystals of tris-methylmercury-oxonium fluoborite have a trigonal symmetry, the hexagonal cell being a = 23.85 A, c = 10.72 A, z = 18 ...

Impaired cross-talk between the thioredoxin and glutathione systems is related to ASK-1 mediated apoptosis in neuronal cells exposed to mercury

Redox Biology, 2017
Mercury (Hg) compounds target both cysteine (Cys) and selenocysteine (Sec) residues in peptides and proteins. Thus, the components of the two major cellular antioxidant systems – glutathione (GSH) and thioredoxin (Trx) systems – are likely targets for ...

Perturbed synaptic adhesion molecules signaling in neurodevelopmental disorders: The impact of metal neurotoxicity

Ibrain, Volume 11, Issue 4, Page 403-421, Winter 2025.
Synaptic adhesion molecules (SAM) are essential for the formation, maturation, function, plasticity, and assembly of synaptic connections, all critical for normal neurodevelopment. Excessive exposure to neurotoxic metals during development could disrupt the developing brain and potentially lead to neurodevelopmental disorders (NDDs).

FIGO committee opinion: Environmental drivers of obstetric health and early childhood development

International Journal of Gynecology &Obstetrics, Volume 171, Issue 3, Page 951-964, December 2025.
Abstract Environmental exposures are increasingly recognized as critical, yet underappreciated, determinants of reproductive, perinatal, and early childhood health. Developed through a structured consensus process and grounded in systematic evidence review, this FIGO committee opinion provides a comprehensive synthesis of the current evidence linking ...

Crosslinked Poly(Acrylic Acid‐Co‐Acrylamide) Applied to Remove Hg(II) and the Effects of Its Exposure on Girardia tigrina

Polymer Engineering &Science, Volume 65, Issue 12, Page 6964-6979, December 2025.
The polymeric adsorption of Hg(II) and the assessment of ecotoxicity. ABSTRACT In this study, an adsorbent was produced by the copolymerization of acrylic acid and acrylamide, followed by cross‐linking. The impact of pH, duration of contact, concentration, presence of interfering ions, and reuse was investigated.

Mercury and selenium relationship in a tropical estuarine fish

Frontiers in Marine Science, 2015
Aquatic systems have been considered as final sinks for persistent and bioaccumulative toxicants (PBTs), such as metals and organohalogen compounds. Among the trace elements, non-essential metals deserve special attention due to their toxicity.

Cytotoxicity and genotoxicity of low doses of mercury chloride and methylmercury chloride on human lymphocytes in vitro

Brazilian Journal of Medical and Biological Research, 2005
Mercury is a xenobiotic metal that is a highly deleterious environmental pollutant. The biotransformation of mercury chloride (HgCl2) into methylmercury chloride (CH3HgCl) in aquatic environments is well-known and humans are exposed by consumption of ...
