Welcome to the October issue of EVISA's Speciation Newsletter!
Mercury is one of those heavy metals that are of concern, since it has no biological function but is a hazardous toxic element. The different mercury species do have different exposure routes and target organs but are all toxic at trace levels. Humans are exposed to inorganic mercury either because of contamination at their workplace or via dental amalgam fillings. Dental surface restorations composed of dental amalgam, significantly contribute to prolonged mercury levels in the body, according to new research from the University of Georgia's department of environmental health science in the College of Public Health (see the news below).
Human exposure to methylmercury is most often via consumption of seafood or other contaminated foodstuffs. Finding the source of mercury contamination in our bodies is crucial for treatment and forensic investigations. An international team from the CNRS, the Universities of Grenoble Alpes,
Bordeaux and Franche‐Comté, France, the ESRF, the European synchrotron
in Grenoble, France and the University of Illinois at Chicago, US, has
developed new analytical capabilities that allow the identification of
chemical forms of mercury in human hair that trace exposure (see the news below).
Mercury toxicity is somehow reduced by the presence of selenium. Selenium is acting as a anti-oxidant and as an antagonist against mercury. The essential element selenium needs to be incorporated into biological active species for providing the functionality. Researchers have now discovered exactly how selenium is incorporated into selenoproteins (see the news below).
These three examples of studies related to metal species highlight the cooperation of scientists from different disciplines necessary to study such complex questions related to the uptake, distribution, metabolism and activity of metal species in organisms.

NEWS
|
| |
| |
EVISA is keeping you updated with what is going on in speciation analysis. In this section you will find news about the most current research results, about trends, legal issues and informations from manufacturers in the field of speciation analysis.
With all the links to further information and publications the News archive is a valuable collection of "hot topics" in speciation analysis. We continuously update even former news with new links and information so that all news are actual all the time.
Researchers discover how selenium is incorporated into proteins
Humans need eight essential trace elements for good health, and one of them is selenium -- a powerful antioxidant that is important for thyroid and brain function as well as metabolism. Researchers have now discovered exactly how selenium is incorporated into selenoproteins.

Too many dental amalgam fillings may increase blood mercury levels
Dental surface restorations composed of dental amalgam, a mixture of mercury, silver, tin and other metals, significantly contribute to prolonged mercury levels in the body, according to new research from the University of Georgia's department of environmental health science in the College of Public Health

Tracking down the source of human exposure to mercury by analyzing human hair
Mercury is a potent neurotoxin present in our daily lives and our body can accumulate it over the years. Food consumption, such as fish and rice, is the most common source of mercury exposure. Mercury can be found in dental amalgams, compact fluorescence lamps, vaccines, drugs, and electronics or can be used in artisanal gold mining. Finding the source of mercury contamination in our bodies is crucial for treatment and forensic investigations, but at present knowledge of the molecular form of mercury in human tissues and fluids, which could indicate source, is limited.
However, an international team from the CNRS, the Universities of Grenoble Alpes, Bordeaux and Franche‐Comté, France, the ESRF, the European synchrotron in Grenoble, France and the University of Illinois at Chicago, US, has developed new analytical capabilities that allow the identification of chemical forms of mercury in human hair that trace exposure. These results are published in Environmental Science & Technology.
