Dear Subscriber !

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

Hexavalent chromium is one of those relatively rare elemental species for which species-related legislation is existing that is meant to limit human exposure. Speciation analysis has to prove compliance with rules. Unfortunately, sample preparation often cannot be avoided, since analysis of solid matrices such as dust, soil, waste, cement or leather is requested. Conversion of hexavalent chromium to trivalent chromium and vice versa may happen during analysis depending on pH and redox conditions. Species-specific isotope dilution analysis, that often is applied in cases of expected species conversion, might fail for solid samples were species equilibration cannot be guaranteed. There is still a lot of work ahead...


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.

Chromium speciation in solid matrices
Speciation analysis for hexavalent chromium in solid matrices is still a great challenge due to the often necessary sample preparation that is prone to induce species conversion.

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 !


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.

Wageningen University: Biosensor nanoarrays for environmental monitoring (BIOMONAR)



Umea University: Mercury Biogeochemistry
The Trace Element Speciation Analysis Research group at the University of Umea (Sweden) seeks a postdoctoral researcher to conduct fundamental studies on mercury-sulfide chemistry in controlled model systems. The project includes design and measurement on model systems in a controlled laboratory environment, and chemical modelling of the results. The aim is to increase the knowledge about mercury-sulfide speciation, and thereby decrease uncertainties regarding the concentrations of bioavailable Hg species under different chemical conditions.

Midi-Pyrenees Observatory (Toulouse, France): Global mercury cycle
A full-time (2yr) Post-Doctoral position is open at the Midi-Pyrenees Observatory (Toulouse, France). We are looking for a candidate in environmental isotope geochemistry to join a recently funded ANR project on the global mercury cycle.

Trent University: Interaction between selenium and reduced sulfur species
The Metalloid Speciation & Geochemistry research group at Trent University is looking for a post-doctoral researcher to study the interaction between selenium species and reduced sulfur species in industrial process streams and ambient waters.
