Mercury is found in the environment as elemental mercury, inorganic mercury or organic mercury (ethyl-, methyl-, alkyl-, or phenylmercury). In our environment it is present in thermometers, thermostats, dental amalgams, paint, cosmetic products, laxatives, diuretics and antiseptics. Organic mercury is the most toxic and most frequent form of mercury exposure, found in fish, poultry, pesticides ...

Mercury is a potent toxicant of concern to both the general public and occupationally exposed workers (e.g., dentists). Recent studies suggest that several genes mediating the toxicokinetics of mercury are polymorphic in humans and may influence inter-individual variability in mercury accumulation. This work hypothesizes that polymorphisms in key glutathione synthesizing enzyme, glutathione S-t...

tention in a series of 12 patients, according to Sodee, and he discontinued the mercuhydrin injection ( 7 ). McAfee noted that pharmacologists have been unable to block the uptake in the kidneys, despite pre-dosing rats with cold mercurials with doses up to 20 mg of mercury per kilogram, a tremendously toxic dose (8). Although brain scanning with such short-lived isotopes as 99mTcand 197Hg is r...

normal 0 false false false en-us x-none ar-sa according to the world health organization (who), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields.   dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population....

Changes in urinary porphyrin excretion patterns (porphyrin profiles) have been described in response to a variety of drugs and chemicals. The present studies were conducted to define the specific changes in the urinary porphyrin profile associated with prolonged exposure to mercury and mercury compounds. In rats, exposure for a prolonged period to mercury as methyl mercury hydroxide was associa...

Mercury is a naturally occurring metal, which can exist in several forms. Metallic mercury is a shiny, silver-white, odorless liquid, which forms a colorless, odorless gas if heated. Mercury combines with other elements such as chlorine, sulfur, or oxygen to form inorganic mercury compounds or salts, which are usually white solids. Mercury also combines with carbon to make organic mercury compo...

Combination of laboratory measurements res ults of various properties, i.e. porosity, density, permeability and mineral composition, was done to get additional factors useful in fluid flow description in the Miocene sandy-shaly formation. Special computer processing of nuclear magnetic resonance outcomes and mercury injection porosimetry results turned out to be useful in the estimation of the ...
