Dear Subscriber !
Welcome to the December issue of EVISA's Speciation Newsletter.
This month we continue our series of "brief summaries" discussing techniques for speciation analysis. The actual brief summary is dedicated to gas-chromatography as a separation module for hyphenated techniques in speciation analysis. Due to its limitation to thermally stable compounds, gas chromatography is the well suited for the determination of organometallic compounds such as tributyltin, tetraethyllead or methylmercury in the environment.
Again mercury is in the news this month. Environmental organizations supported by scientists argue that mercury is reaching humans via the food chain at levels creating a dangerous health risk. They are planning to present their recent findings at the next and final round of UNEP negotiations to put in place a legally binding global treaty to reduce mercury use and pollution. While these scientists will urge the politicians for an effective ban of mercury, the American Academy of Pediatrics has endorsed the World Health Organization's stance that thimerosal -- a mercury-based preservative -- should be left in vaccines and should not be subject to a ban (see the news below).
The outcome of these negotiations, taking place next month, will certainly also reflect the influential power of the lobby groups behind (environmental NGOs vs. pharmaceutical industry). We will keep you informed !
We thank you all for your interest and your fidelity.
We wish you a Merry Christmas and a Happy and Prosperous Year 2013
Your EVISA team

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.
Experts Argue to Keep Thimerosal in Some Vaccines
According to a statement published online December 17 in Pediatrics, the American Academy of Pediatrics has endorsed the World Health Organization's stance that thimerosal -- a mercury-based preservative -- should be left in vaccines and should not be subject to a ban contained in a draft mercury treaty from the UNEP.

Gas chromatography for the separation of elemental species
Gas chromatography is a very effective sample introduction technique for atomic spectroscopy because of the absence of a condensed mobile phase and the very high separation efficiency. Unfortunately, it is limited solely to organometallic compounds which are volatile and thermally stable in the native form or which can be converted to a volatile form by means of derivatizaton.

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 Pau, France: Methods for the determination of redox forms of chromium and organotin compounds
The 2009/48/EC toy safety European directive was recently modified taking into account the emergence of new manufacturing processes and innovations concerning materials and technologies used. This directive went into effect since July 20, 2011 but will come into force from July 20, 2013 regarding chemical requirements.

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 275 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.
