Dear Subscriber !
Welcome to the September issue of EVISA's Speciation Newsletter.
Mercury is a global pollutant. Most of the harm related to mercury comes from methylmercury bioaccumulation, which is the buildup of the element in tissue that occurs when moving up the food chain. A group of researchers now show that the biogeochemical cycling of the element is more complex than thought. Much more microbes than previously known are able to transform inorganic mercury into methylmercury, including microbes that live in rice paddies, northern peat bogs and other previously unexpected environments (see the news below).
Methylmercury is a strong neurotoxin. Canadian scientists now have found how methylmercury directly affect vision by accumulating in the retinal photoreceptors, i.e. the cells that respond to light in our eyes (see the news below). This is a good example to highlight how trace element imaging can help to investigate the toxic action of toxic metal species.

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.
Toxic Methylmercury-Producing Microbes More Widespread Than Realized
Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury, researchers at Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have learned.

EVISA provides information about open positions for Ph.D. students, PostDocs and permanent staff in the field of speciation. Looking to fill a vacancy or needing a new career challenge? Either way this service is FREE. Many laboratories and research facilities (from Greenland to Crete) have already found their highly educated stuff through this service by EVISA. If you would like to post an open position here, please contact us at info@speciation.net !
Doctorates
University of Lleida (Spain): Electroanalytical techniques for speciation analysis
The research group in the Universitat de Lleida (Catalonia, Spain) offers a PhD position, meant to continue the development of the new electroanalytical technique AGNES, while comparing and improving other techniques (DMT, DGT, etc.) to gain an understanding of the distribution of a metal ion in its chemical forms and the ensuing (bio)availability. Possible applications: environmental, toxicological and agrifood studies (from dissolution of nanoparticles in natural waters to the impact of metals on the quality of wine).

|
EVISA's directory of scientist is a versatile tool to facilitate contact with scientists in the field of speciation and related sciences. The directory is fully searchable for names, addresses, research topics etc. You should bookmark this directory as an always up-to-date address book. (In order to hinder SPAM robots for collecting the E-mail accounts, we hide them in a special format).
More than 280 active scientists in the field of speciation analysis already joined the directory. Join this great directory that is extensively linked to all type of other information on this site, such as homepages, conferences and literature.
If your entry is still missing in this directory, please contact us at info@speciation.net.
