The characterization of an optical sensor membrane is described for the determination of Hg2+ ions based on the immobilization of 5, 6 Di methyl -1- ( 4 methyl benzyl) -2- para tolyl-1H-benzimidazole (DMBPTBI) on a triacetylcellulose membrane. The membrane responds to mercury ions by changing color reversibly from orange to red in universal buffer solution at pH 2. Under optimum conditions, the...

In 1940 Hunter and others, reporting on cases of poisoning by methyl mercury compounds, showed that those working with certain organic mercury derivatives are exposed to great danger. In 1945 Herner collated the cases of poisoning by alkyl mercury compounds recorded in' the literature. The seven cases hitherto published show a characteristic clinical picture beginning with a sensation of numbne...

We have studied the brain regional distribution of methyl mercury following intravenous administration of CH3 203HgCl in rat. Early peak levels were obtained in cerebellum, medulla oblongata and midbrain. The efficacy of removal of 203Hg by different chelators is also region dependent. The most efficient chelator for brain mercury proved to be mesodimercaptosuccinic acid.

Dubbed “quicksilver” by Aristotle,[1] mercury is a heavy metal with unusual physical characteristics, such as a low melting point,[2] that make it suitable for a variety of uses. It can be found in countless modern-day products, from thermometers and fluorescent light bulbs to dental fillings. Unfortunately, this unique metal is toxic to humans, and exposure can lead to neurological damage, com...

Lead, arsenic, cadmium, and methyl mercury are nonessential and potentially highly toxic metals. They may be found in minute and variable but measurable amounts in food, drinking water, and/or ambient air. Because each of the metals has been identified as a serious environmental contaminant in various parts of the world, much research effort has been devoted to them, especially during the past ...

Polymer optical fiber (POF) with a highly photosensitive poly(methyl methacrylate-co-methyl vinyl ketone-co-benzyl methacrylate) core is fabricated. Gratings can be fabricated in the core of a POF with a low-cost mercury lamp. The part of the emission spectrum of the mercury lamp in which the cladding material exhibits photosensitivity is effectively filtered by a 1.5-mm-thick Pyrex glass to en...

Coal-fired power plants are by far the largest source of mercury pollution in the US. Through the coal-combustion process, they emit approximately 50 tons of mercury particulates into the atmosphere every year (EPA, 2005 data). When the mercury falls back to earth it is deposited on the land and gets into the water ecosystem, where it is converted into the highly toxic organo mercury compound, ...
