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

The effects of natural methylmercury compounds on regeneration of photoreceptor organs were studied in three freshwater planarians: Polycelis tenuis, Dugesia lugubris, and D. tigrina. Accumulation of methyl mercury in the planarian body suppressed regeneration of P.

Abstract Methylmercury (CH3Hg(II)) was measured in various tissues and whole body of sheepshead minnows, Cyprinodon variegatus, following exposure to 100 ng/L methylmercury chloride (CH3HgCl) alone or in combination with one of the organic compounds cysteine (CH3Hg-Cys), thiourea (CH3Hg-Thu), or thioglycolate (CH3Hg-Thg).

The Analyst, 1992
Two novel and convenient methods for obtaining volatile mercury and methylmercury species for analysis that allows non-volatile analyte solutions to be identified by element-specific and species-selective techniques are described. Non-volatile aqueous solutions of mercury(II) and/or methylmercury(II) compounds are converted into volatile forms ...

Humic and fulvic acids from lakes in Ontario, Canada, have been isolated and been examined for their ability to bind methylmercury(II). Equilibrium dialysis has been applied to differentiate between bound and unbound fractions of MeHg(II). Losses of methylmercury(II) from solutions containing 0.5−100 ng/L MeHg(II) and 10 mg/L humic substances (HS) are ...

Toxicity of Mercury and Its Compounds
Chemistry at SchoolThe historical context of the accumulation of knowledge about the toxicity of mercury and its compounds is given, from the use of calomel as a medicine to the tragic events of mass poisoning with methylmercury in the Japanese province of Minamata.

Considerable levels of methylmercury (MeHg) have been found rice-based infant cereals as a result of MeHg transfer from the rice as a raw material to the products, hence consumption of rice products may pose a potential health risk to infants who may receive cereals as the major diets and are susceptible to toxicity of MeHg.
