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

One of the species in the focus of regulation is hexavalent chromium.  Since hexavalent chromium is carcinogen, its presence in food or the environment cannot be tolerated. Therefore alarming reports about Cr(VI) found in foodstuffs such as milk, mushrooms or bread make their way into the news. Since on the other site, hexavalent chromium is a strong oxidizing agent, it is questionable whether such species can be present within organic matter that can easily reduce hexavalent chromium. We at EVISA already some years before questioned such reports and speculated that such findings result from inadequate speciation analysis. Now a group of French researchers developed a sensitive method for chromium speciation with optimized extraction of hexavalent chromium from different foodstuffs. With a quantification limit below 1 µg/kg there were not able to detect any Cr(VI) in cereals or dairy products (see the news below). 

Arsenic is one of the elements most often studied for its speciation. More than 100 different compounds have been identified in nature and researchers add to this number every year. Another element of the same group in the periodic table, namely antimony is much less studied. A group of researchers from Switzerland now measured for the first time the uptake and translocation  of trimethylantimony in a plant using a new method for extraction and speciation analysis. The authors are convinced that their method opens the door for further studies of the soil-plant system with respect to antimony species  (see the news below).

We frequently report about methylmercury, since humans are exposed to this strong neurotoxin via consumption of seafood, with increasing levels because of anthropogenic emission of mercury via coal combustion. Now a study funded by the National Institute of Environmental Health Sciences (NIEHS) has investigated how methylmercury exposure in the womb may affect cognitive function in adults. The results indicate that prenatal mercury exposure cancels out cognitive benefits of exercise (see the news below).

Such topic related to trace metal speciation  have been discussed during the conference "TraceSpec 2016" that took place in Gdansk (Poland) two weeks ago (Sept. 4-7, 2016). Researchers from all over the world came together to discuss the Progress in Trace Metal Speciation for Environmental Analytical Chemistry. The next issue will be organized by Montserrat Filella in Geneva (Switzerland) in 2018 and EVISA Director Michael Sperling will act as the co-chair. We will inform you about this unique conference devoted to speciation analysis.


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.

Prenatal Mercury Exposure Cancels Out Cognitive Benefits of Exercise
Cognitive function improves with aerobic exercise, but not for people exposed to high levels of mercury before birth, according to research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health (NIH). Adults with high prenatal exposure to methylmercury, which mainly comes from maternal consumption of fish with high mercury levels, did not experience the faster cognitive processing and better short term memory benefits of exercise that were seen in those with low prenatal methylmercury exposures.

Plant uptake of trimethylantimony from contaminated soils
A group of researchers from Switzerland measured for the first time the uptake and translocation of trimethylantimony in a plant using a new method for extraction and speciation analysis.

New sensitive method for chromium speciation analysis: No hexavalent chromium in dairy and cereal products
French researchers could not detect any hexavalent chromium in dairy and cereal products using a new optimised method for selective alkaline extraction followed by HPIC-ICP-MS determination.

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.
