High impact information on methylmercury

• Phosphorescence/microwave double-resonance spectra of tryptophan perturbed by methylmercury(II) [1].
• Heavy metal-nucleoside interactions. Binding of methylmercury(II) to inosine and catalysis of the isotopic exchange of the C-8 hydrogen studied by 1-H nuclear magnetic resonance and raman difference spectrophotometry [2].
• As expected, methylation of mercury is not a reaction pathway; traces of methylmercury(II) are artifacts of the extraction/preconcentration procedure used for methylmercury analysis [3].
• Of the remaining 6 chemicals one, methylmercury(II) chloride, was positive in the FIX system but not in ZESTE, while MEA was positive in ZESTE and borderline in FIX [4].
• 15. Reactions of calf thymus DNA with the electrophiles methylmercury(ii) nitrate, cis-dichlorodiammineplatinum(ii), and trans-dichlorodiammineplatinum(ii) studied using raman difference spectroscopy Evidence for the formation of c-DNA upon metalation [5].

Biological context of methylmercury

• Binding of methylmercury(II) by HeLa S3 suspension-culture cells: intracellular methylmercury levels and their effect on DNA replication and protein synthesis [6].
• Although the primary human exposure is from ingestion of fish contaminated with methyl mercury (HgCH3), exposures to elemental mercury vapor and mercury compounds via inhalation and dermal contact may also occur [7].

Associations of methylmercury with other chemical compounds

• A High-Performance Liquid Chromatography (HPLC) system coupled with Inductively Coupled Plasma Mass Spectrometry (ICP-MS) detection has been developed to further resolve the species information into soluble inorganic species (Hg(2+)), methylmercury(II) (MeHg(+)) and ethylmercury(II) (EtHg(+)) species [8].
