Elemental mercury (Hg(0)) in flue gases can be efficiently captured by mercury chloride (HgCl2) solution. However, the absorption behaviors and the influencing effects are still poorly understood. The mechanism of Hg(0) absorption by HgCl2 and the factors that control the removal were studied in this paper. It was found that when the mole ratio of Cl(-) to HgCl2 is 10:1, the Hg(0) removal effic...

Currently, mercury has been identified as a risk factor of cardiovascular diseases among humans. Here, the authors tested the hypothesis that mercury modulates the activity of the endothelial lipid signaling enzyme, phospholipase D (PLD), which is an important player in the endothelial cell (EC) barrier functions. Monolayers of bovine pulmonary artery ECs (BPAECs) in culture, following labeling...

An automatic microgravimetric screening system based on piezoelectric detection and the use of acidic stannous chloride as reductant was developed for the fast detection and determination of total mercury in water. Reduced mercury is detected as an amalgam by using a gold-coated piezoelectric crystal, the sensor subsequently being regenerated by passing it through a peroxydisulfate solution. Th...

The aim of this study was to evaluate the efficiency of oral treatment with sodium 2,3-dimercaptopropane-1-sulfonate (DMPS) on reducing mercury deposits in rat kidney after chronic exposure to inorganic mercury. The effect on kidney copper levels was also evaluated. The results showed that after two months of exposure to 50 ppm of mercury (as mercuric chloride) the concentration of mercury in t...

Both pentafluorophenylmercury chloride and trimeric perfluoro-ortho-phenylene mercury interact with phenanthrene to form phosphorescent adducts which exhibit extended binary stacks in the solid state.

The detection of toxic trace metals in the environment is a highly important yet challenging analytical problem. Because of the growing awareness of environmental mercury pollution and its high toxicity, it is becoming more urgent to develop highly sensitive techniques for the detection of Hg (1). Spectroscopic techniques such as coldvapor atomic fluorescence spectrometry (CV-AFS),(2) cold-vapo...

Because of the inherent sensitivity of the dropping mercury electrode when used for the quantitative analysis of inorganic ions, the present study was undertaken to determine whether sufficient accuracy and simplicity of operation could be attained to justify its employment as a micromethod for the determination of chloride in blood. Since it was desired to work with such samples as can be conv...

The objective of this study was to evaluate the effect of heavy metals, at environmentally relevant concentrations, on the immune response of rainbow trout. Trout were exposed for 30 d to cadmium chloride (CdCl2), mercuric chloride (HgCl2), or zinc chloride (ZnCl2) either individually or in combinations: CdCl2/HgCl2, CdCl2/ZnCl2, HgCl2/ZnCl2, or CdCl2/HgCl2/ZnCl2. Following the 30-d exposure, p...

This study was designed to evaluate the effects of simultaneous coexposure to inorganic mercury and cadmium on the renal and hepatic disposition of each metal. Dispositional changes were assessed in rats 1 h and 24 h after the coexposure to relatively low doses of the metals (which individually are nonnephrotoxic in rats). The rational for studying mercury and cadmium is that both of these meta...
