occupational exposure to elemental mercury vapor usually occurs through inhalation during its utilizations. this leads to a variety of adverse health effects. in some islamic cities, this type of poisoning may occur during gilding of shrines using elemental mercury with gold. herein, we report on three male patients aged 20–53 years, who were diagnosed with occupational metallic mercury poisoni...

Fast and reliable analytical methods for mercury speciation would aid in understanding mercury offgas chemistry. Presently, the U.S. Environmental Protection Agency (EPA) regulates only total mercury; however, many studies indicate that mercury toxicity is highly dependent on the mercury speciation. For example, amalgams and mercury sulfides have relatively low toxicities, while organomercury a...

Mercury is a toxic and non-essential metal in the human body. Mercury is ubiquitously distributed in the environment, present in natural products, and exists extensively in items encountered in daily life. There are three forms of mercury, i.e., elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. This review examines the toxicity of elemental mercury and...

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...

Mercury is known to be a toxic material with adverse effects on the body as claimed by so many researchers and always projected a negative aspect of this element. It is true that it may cause a several problems when it exceeds the safe limit but along with its negative image, mercury has been playing a positive role in the field of medicine and dentistry. It has many therapeutic uses including ...

This contribution is based on our presentation at the 1 International Symposium on Sensor Science, Paris, 16-20 June 2003. It presents recent results regarding the electrochemical determination of submicromolar and nanomolar concentrations of various carcinogenic substances (nitrated polycyclic aromatic hydrocarbons, heterocyclic compounds, azo compounds, aromatic amino compounds, etc.) using b...
