The marine mussel, Mytilus edulis, possesses low molecular weight, metal-binding proteins which can be induced by and, in turn, bind mercury when individuals are exposed to low, but elevated concentrations of mercury as HgCl2. Induction of the proteins by exposure of mussels to copper, cadmium, or mercury is associated with enhanced tolerance to mercury toxicity. Mercury-binding proteins isolat...

A comprehensive evaluation of the chemical forms heavy metals, rather than their total amount elements, is basis scientific and objective safety in metals. As mercury, most toxic metal environment (such as water, soil, air), accumulates medicinal plants, mercury plants preparation need to be clearly understood. This study aims summarize status bulk Chinese herbs traditional medicine preparation...

To measure the hazard to the worker it is often necessary to determine the atmosphere concentration of mercury in a workroom. It should be borne in mind that inhalation of mercury, though probably the most dangerous, is not the only way by which mercury enters the body. It follows that a measurement of the mercury content of the atmosphere does not give a full indication of the hazard. Air anal...

The properties of ionic liquids on ordered and non-ordered mesoporous silicas (silica gel, MCM-41, SBA-15) were studied by nitrogen sorption, mercury intrusion and thermogravimetric analyses, as well as (129)Xe-NMR spectroscopy. The ionic liquids investigated are based on the 1-hexyl-3-methylimidazolium cation, which was combined with anions of low (bis(trifluoromethanesulfonyl)imide; [NTf2](-)...

A chemical kinetic mechanism for the atmospheric chemistry of inorganic mercury has been developed. Computer simulations conducted with this mechanism suggest that the half-life of elemental mercury could be of the order of hours for reaction with Cl2 in a nocturnal marine layer and for reactions with oxidants such as H202 in the ambient atmosphere. However, large uncertainties exist in the gas...

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

The power deposited by a 20 MW beam of 2 GeV protons has been calculated for a Liquid Mercury Target. Beam size and shape critically influence the deposited power density. A principle limitation of the liquid metal is in the temperature range that can be considered should boiling be avoided while operating at a relatively high repetition rate (> 50 Hz). This has a limiting effect on the power t...

Mercury has a strong environmental impact since both its organic and inorganic forms are toxic, and it represents a pollutant of global concern. Liquid Hg is highly volatile and can be released during natural and anthropogenic processes in the hydrosphere, biosphere and atmosphere. In this study, the distribution of Gaseous Elemental Mercury (GEM) and the total and leached mercury concentration...

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...

Urine is a liquid waste product of the body. Substances that are ingested and fail to be apsorbed are excreted, solid waste through the intestines, the urine through the kidney and ureter and another fluid from the body through perspiration. Determination of mercury content of urine is not included in routine examinations, but mercury can be present in urine at concentrations that could have se...
