Welcome to the May issue of EVISA's Speciation Newsletter !
One of the most often cited element when it comes to speciation analysis is chromium. Chromium is the example when the value of speciation analysis has to be explained: While chromium (III) is often claimed to be essential, chromium (VI) is known to be carcinogen.
While chromium (III) is legally allowed to be included in food supplements, multi-vitamin and mineral tablets, hexavalent chromium is legally controlled in order to avoid human health risks.
EVISA has often reported about this ambivalent characteristics (see the EVISA news related to chromium).
Hexavalent chromium is a strong oxidant and therefore is not stable in presence of substances that can easily be oxidized. For this reason, hexavalent chromium cannot exist for longer times in biological materials such as blood, tissue or food materials. We therefore have always doubted reports about the determination of hexavalent chromium in such materials. Now some experts in chromium speciation analysis have developed a method for the determination of Cr(VI) in different foodstuffs. Guess what they found ! (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.
Hexavalent chromium in food ?
Researchers from Pau (France) developed a HPLC-ICP-MS method for the chromium speciation analysis of foodstuffs. Using the method with a detection limit in the order of 10 µg/kg no hexavalent chromium was found in any of the samples analysed.
