Welcome to the July issue of EVISA's Speciation Newsletter !
Chromium speciation has been studied frequently, and also is in the EVISA News quite often. The focus is on hexavalent chromium that is carcinogen and therefore cannot be accepted in food. We at EVISA have always argued that Cr(VI) is not stable in biological material and therefore its detection in food is probably an analytical artifact. We also argued that results showing the presence of Cr(VI) in biological materials should be verified by species-specific isotope dilution analysis, a method that can produce accurate results even when species transformations occur during analysis. Researchers from France and Denmark now just used such method for the determination of Cr species in bread and breakfast cereals. As we expected, no Cr(VI) was found in any of their samples (see the news below).
Another species often creating headlines is methylmercury, the most toxic form of mercury present in the environment. Its bioaccumulation and biomagnification in the marine food web starts from its presence in seawater at very low concentrations. The determination of such low concentrations in the complex sample matrix of seawater calls for a highly sensitive and selective speciation method. Researchers from the IAEA Environment Laboratories in Monaco have now not only developed such method but also validated the method following Eurachem guidelines (see the news below).
Vitamin B12, also known as cobalamin, is a coordination complex of cobalt that has many essential biological functions. It is important in the normal functioning of the nervous system via its role in the synthesis of myelin and plays a significant role for the neurological development of infants. Its quantification in human milk is therefore of great interest. The main challenge for the determination of the vitamin B12 in human
milk is its low concentration which is generally one order of magnitude
lower than in cow's milk. Researchers from the Nestlé Research Laboratories have now presented a new
accurate and robust method for quantification of vitamin B12 in human
milk (see the news below). n more so after repeated GBCAs administration.
Due to the ongoing COVID-19 pandemic, many of the conferences scheduled for before September have been postponed or modified to virtual events. Some conferences scheduled for September and later of the year are foreseen as meetings with personal presence. EVISA's Agenda of Events is frequently updated in order to keep you informed about the organization of relevant events.

NEWS
|
| |
| |
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 information 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.
Determination of Vitamin B12 in human milk
Researchers from the Nestlé Research Laboratories have presented a new accurate and robust method for quantification of vitamin B12 in human milk. The method is based on a highly specific sample preparation associated with chromatographic separation and detection by ICP-MS.

Ultratrace determination of methylmercury in seawater using automated GC-AFS
Researchers from the IAEA Environment Laboratories in Monaco have developed a highly automated method for the ultratrace determination of methylmercury in seawater. The developed method was optimized fully validated following Eurachem guidelines.

Chromium speciation analysis in bread and breakfast cereals
Researchers from France and Denmark now aimed at clarifying conflicting results for the presence of hexavalent chromium in bread and breakfast cereals. Using highly selective separation by HPLC coupled with ICP-MS detection and species-specific isotope dilution for quantification they found no Cr(VI) in any of their samples.
