The total mercury (T-Hg) and methyl mercury (Me-Hg) concentrations in the hair were measured to evaluate mercury (Hg) exposure for the residents in Da-shui-xi Village (DSX) and Xia-chang-xi Village (XCX) in the Wanshan Hg mining area, Guizhou Province, Southwestern China. The mean concentrations in the hair of DSX residents were 5.5 ± 2.7 μg/g and 1.9 ± 0.9 μg/g for T-Hg and Me-Hg, respectively...

the objective of this study was to determine the relationship between body weight (bw) and heart girth (hg) in sardi and timahdite sheep in order to develop a prediction equation of bw from hg. the data used for this study included 476 records on bw and hg (227 in sardi and 249 in timahdite) collected on males and females of different ages in 33 private farms. the bw and the hg averaged 34.8 ± ...

In order to study the interaction of cysteine containing peptide chains with Hg(II) the nuclear quadrupole interaction (NQI) of 1 9 9 m Hg in the Hg complex of the oligopeptide Alanine-AlanineCysteine-Alanine-Alanine (AACAA) was determined by time differential perturbed angular correlation. Different 1 9 9 m H g N Q I ' s for free and resin-bound A A C A A were obtained. Furthermore, the 1 9 9 ...

Combination of the hydrochloride salt of cysteamine (1) with HgCl2 in water affords the unique compound, [Hg{S(CH2)2NH3}2](Cl)2 (2) in which the S Hg S angle is nearly linear. The ammonium portion of the molecule forms short hydrogen bonding contacts with the sulfur atoms. A related S···H bond is observed in the structure of the free ligand 1 indicating that such bonding does not require the pr...

As mercury (Hg) biosensors are sensitive to only intracellular Hg, they are useful in the investigation of Hg uptake mechanisms and the effects of speciation on Hg bioavailability to microbes. In this study, bacterial biosensors were used to evaluate the roles that several transporters such as the glutathione, cystine/cysteine, and Mer transporters play in the uptake of Hg from Hg-thiol complex...
