Dear Subscriber !

Welcome to the December issue of EVISA's Speciation Newsletter.

Scientific knowledge is not universal but a matter of discussion. What has been discussed as being the "truth" has to be revisited again in the light of new results. This is especially true within life science, where the actual advances are substantial.

Two of our actual news of the month do show in which way our knowledge may change: A study on the nutritional value of trivalent chromium, which for a long time has been deemed to be actively involved in the glucose metabolism, is now concluding that chromium (III) is not essential at all. Actually the active species, the glucose tolerance factor (GTF) has never been found (see the news below).

A NASA study claims to have discovered a bacterium that can live without phosphorous, an element that has been considered to be a building block for life. The scientists reported to have found a bacterium that has used arsenic instead of phosphate even to build up its DNA. If the preliminary results of this highly questioned study can be confirmed that would be a first indication for the possibility of alternative biochemistries for life.

The role, functions and mechanisms of metallic species in organisms is the focus of metallomics. Scientists being active in that field will meet next year in June 15-18 in Münster, Germany for the Third International Symposium on Metallomics.  Please feel invited to join us for this stimulating event. The call for papers is open now !

We wish you a Merry Christmas and a Happy and Prosperous Year 2011

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.

Arsenic, an element of archaic life ?
A NASA researcher has discovered a bacterium that can live without phosphorous, substituting arsenic instead.

ECHA reports the final REACH registration numbers - Nearly 25,000 dossiers
Yesterday (November 30, 2010) marked the first deadline for registration of chemicals under the European Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program. And the European Chemicals Agency (ECHA) has quickly issued a press release summarizing the results - "ECHA had received 24,675 registration dossiers, submitted for nearly 3,400 phase-in substances."

Deemed Essential to Health for Decades, Chromium Has No Nutritional Effect, UA Researchers Show
Despite a long-held acceptance that healthy diets must incorporate chromium III, new research indicates the element has no nutritional benefit, according to a paper authored by University of Alabama researchers.

New certified reference material supporting mercury speciation analysis of blood
A whole blood certified reference material, NIST SRM 955c Toxic Elements in Caprine Blood was developed for the determination of toxic metals in whole blood including mercury. The certification of methylmercury, ethylmercury, and inorganic mercury was carried out by triple spike speciated isotope dilution inductively coupled plasma mass spectrometry (TS-SID-GC/ICP-MS) and represents the first whole blood material certified for three mercury species.


With a list of about 50 current entries EVISA is informing you about interesting events and keeps you updated with their deadlines. By consulting our list of deadlines you won't miss the opportunity for early registration at reduced fee or the chance to submit your contribution in time.

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 !


Helmholtz Zentrum Muenchen; Short Term Marie Curie Fellowships for PhD students in Environmental Chemistry
Investigation of the influence of chemical speciation on the accuracy of QSPR/QSAR models:
The biological activity and fate properties of chemicals can drastically change depending on whether ionic or neutral forms of molecules are present in the environment. The difficulties with this task are frequently connected to low accuracy of existing methods to predict dissociation constants of molecules. The pKa model or otherwise calculated dissociation constants and/or experimental dissociation constants of molecules will be used to address this question and explore whether use of chemical speciation can increase accuracy of QSPR / QSAR models.

UMCES - Chesapeake Biological Laboratory in Solomons, MD; Lanthanide uptake in aragonite and calcite
Three years of NSF funding for a Ph.D. student is immediately available at the UMCES - Chesapeake Biological Laboratory in Solomons, MD. Focus of the research is lanthanide uptake in aragonite and calcite, and its use in ocean acidification studies.

University of Liverpool: Iron speciation and humic substances in seawater
It is proposed that the student in this project makes a detailed study of the chemical speciation of iron and the concentration of iron-binding HS. Previous work has demonstrated the presence these ligands in Liverpool Bay and the Irish Sea. We will now concentrate on the estuary of the Mersey as a source of these ligands. The work may be extended to the Irish Sea. Samples will be collected during cruises with the University research vessel or the Environment Agency.


University of Cologne, Botanical Institute: Ionomics of mycorrhizal plants
The Botanical Institute of the University of Cologne is currently looking for a highly motivated postdoctoral scientist to join our research on ionomics of mycorrhizal plants.
