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

Arsenic is one of the most often analysed element with respect to its species distribution. Since inorganic species are the most toxic ones, their presence in food should be carefully watched and limited. While seaweeds are known to have nutritional values, they also contain higher arsenic than most foods and beverages. Researchers from U.S. FDA have now analysed 46 seaweed samples purchased from the U.S. market for total arsenic and arsenic speciation. A total of 15 known and 14 unknown arsenic species were identified in those samples (see the news below).

Interconversion between the two thermodynamically stable iron species Fe(II) and Fe(III) plays a fundamental role for the iron cycling in the environment as well as its essential role for living organisms. Since Iron is the fourth most abundant element in the Earth’s crust, its concentration in environmental samples often does not call for very sensitive trace detection. Researchers from Poland now have compared microwave induced plasma optical emission spectrometry (MIP OES) and inductively coupled plasma optical emission spectrometry (ICP OES) for the detection of iron species separated by HPLC. The detection power of HPLC-ICP-AES was 10-20 time better than those obtained by HPLC-MIP-AES (see the news below).

Normally at the end of this month the holiday season would be finished and conferences and symposia would be scheduled. Indeed,
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.

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.

Arsenic Species in Seaweeds Commercially Available in the United States
Researchers from U.S. FDA have analysed 46 seaweed samples purchased from the U.S. market for total arsenic and arsenic speciation. Arsenosugars were dominant in most seaweeds, inorganic arsenic did not exceed 250 ng/g except for knotted wrack, oarweed and hijiki.

Iron species determination by high performance liquid chromatography coupled with plasma source atomic emission spectrometry
Researchers from Poland have compared microwave induced plasma optical emission spectrometry (MIP OES) and inductively coupled plasma optical emission spectrometry (ICP OES) for the detection of iron species separated by HPLC. The detection power of HPLC-ICP-AES was 10-20 time better than those obtained by HPLC-MIP-AES.

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.
