Mercury cell chlor-alkali products are used to produce thousands of other products including food ingredients such as citric acid, sodium benzoate, and high fructose corn syrup. High fructose corn syrup is used in food products to enhance shelf life. A pilot study was conducted to determine if high fructose corn syrup contains mercury, a toxic metal historically used as an anti-microbial. High ...

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...

The spontaneous and chelator mediated excretion of mercury in urine was investigated in male subjects occupationally exposed to mercury vapour (alkaline battery and chloralkali plants) who did not exhibit any sign of kidney damage. The time course of the spontaneous elimination of mercury in urine was examined in seven workers (age 22-40) who had been removed from exposure to mercury vapour (av...

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, ...

A simple design of a ratiometric fluorescent sensor for detecting Hg(II) ion in 100% aqueous solution was demonstrated, based on the structure of dimerized Cys residues with two dansyl fluorophores. The sensor highly sensitively and selectively detected mercury ion (K(d) = 41 nM) in 100% aqueous solution via a turn-on and ratiometric response. The sensor showed no interferences of other metal i...

mercury is one of the most toxic heavy metal which can enter the human body mainly through consumption of seafood contaminated with mercury. in this study, the human health risk due to consumption of kutum (rutilus frisii kutum), in the caspian sea, were evaluated by measuring the concentration of mercury in muscle samples using atomic absorbtion spectrophotometer (perkin elmer fias-100) and co...

FOREWORD This report provides recommended guidelines for consumption of fish from Lake Pillsbury (Lake County). These guidelines are provided to the public as a result of findings of high levels of mercury in fish tested from Lake Pillsbury. These recommendations are provided to protect against possible adverse health effects that may result from consumption of mercury-contaminated fish. The re...

mercury is the most toxic heavy metal in the aquatic ecosystems which originates both from natural and industrial resources and is ultimately deposited in sediments as methyl mercury. this metal is quickly transferred through the food chain and accumulated in organisms. in this study, the human health risk due to consumption of mullet ( liza aurata ) in the caspian sea, were evaluated by measur...

THE LOSS OF MERCURY due to volatilization and incomplete removal of oxidizing agents which destroy dithizone are among the major problems in determining mercury in urine. This paper describes a method by which these difficulties are reduced to a minimum. In actual use, this method has been found efficient in screening large numbers of workers exposed to a mercury hazard. Most methods require a ...
