Welcome to the October issue of EVISA's Speciation Newsletter !

According to the IUPAC definition of chemical species, isotopic analysis is part of speciation analysis. During the last decade, stable isotope analysis has gone far beyond the typical elements being analysed by stable isotope ratio mass spectrometry (SIRMS) such as O, N, C, towards metals such as Sr, Pb, Hg and other elements measured by multicollector ICP-MS. By analyzing the isotopic composition, valuable information can be gained that helps to classify the analyzed material with respect to origin, history, or other environmental parameters. In a recent study by a group of european researchers mercury isotope composition in the european seabass is used to differentiate seven distinct populations (see the news below).

We frequently reported about gadolinium used as a contrast agent for medial imaging by magnetic resonance (MRI). While considered to be safe, recent studies have reported that small amounts of applied gadolinium may be retained in the human body and especially also in the brain. Researchers from the University of Münster now have developed a method for the quantitative spatial mapping of gadolinium in tissue sections. Using the developed method they were able to detect and quantify gadolinium in a human brain two years after the gadolinium-based contrast agent was used (see the news below).


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.

Gadolinium found in the brain of a patient two years after having received a Gd-based contrast agent for medical imaging
A group of researchers from Münster (Germany) found gadolinium in different brain regions of a patient post mortem with highest concentreations above 800 ng/g more than two years after having received a linear Gd-based contrast agent for diagnostic imaging.

Seabass populations can be differentiated by their Mercury Isotope Distribution
A group of european researchers has analyzed the mercury isotope composition in marine fish for seven distinct populations of the European seabass. Mercury isotopic values provided information on mercury contamination sources for biota in coastal environment and enabled the discrimnination of several seabass populations.

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.
