A concentrated review on the toxicology of inorganic mercury together with an extensive review on the neurotoxicology of methylmercury is presented. The challenges of using inorganic mercury in dental amalgam are reviewed both regarding the occupational exposure and the possible health problems for the dental patients. The two remaining "mysteries" of methylmercury neurotoxicology are also bein...

Mercury deposition histories have been scarcely documented in the southern hemisphere. A sediment core was collected from the ecologically important estuarine floodplain of the Berg River (South Africa). We establish the concentration of Hg in this (210)Pb-dated sediment core at <50 ng g(-1) Hg(T) throughout the core, but with 1.3 ng g(-1) methylmercury in surface sediments. The (210)Pb dating ...

Adsorption of mercury(ll) and methylmercury by two tannin sorbents was investigated using radiotracers. High sorption capacities for mercury are registered for both sorbents at pH 7. For Eucaliptus Saligna Sm sorbent (ETS) the maximum sorption capacity was 1.2_+.0.2 mmol/g and for Lysiloma latisiliqua sorbent (LTS) was 8.5+0.2 mmol/g. Methylmercury adsorption maximum was recorded at pH 4 and in...

We consider the problem of estimating the effect of exposure on multiple continuous outcomes, when the outcomes are measured on different scales and are nested within multiple outcome classes, or "domains." Our Bayesian model extends the linear mixed models approach to allow the exposure effect to differ across domains and across outcomes within domains. Our model can be parameterized to allow ...

Cats fed (CH3Hg)2SO4 developed the same findings as spontaneously affected cats fed the poisonous seafood from Minamata Bay. The organomercury compound in raw organs such as the liver, the kidney, and the bone marrow of the above animals did not transfer to chloroform , but it transferred easily to BAL. The methylmercury compound in organs of cats fed (CH3Hg)2SO4 and rats fed CH3HgI accumulated...

The present experiment was designed to access the effects of Methylmercury chloride ( MeHgCl) on antioxidant status, protein concentration, lipid peroxidation and hydroperoxidation in brain parts, spinal cord, lung, heart and pancreas of rats. Twenty male Wistar rats (3 months old) were divided in saline controls (C) and MeHgCl-treated group (MMC). Treated rats were intoxicated with MMC ...
