Welcome to the July issue of EVISA's Speciation Newsletter !
An important reason for discussing the speciation of trace elements is that toxicity depends on the presence and concentration of toxic species rather than on the elemental constituent itself. For example, while arsenic is often synonymous with poison, arsenobetaine, the primary form of arsenic in fish, is as harmless as table salt. To ensure food safety and accurately evaluate health risks for consumers, it is crucial to determine the speciation of trace elements with a focus on their toxicity. Major arsenic species include inorganic forms, such as arsenite (iAsIII) and arsenate (iAsV), as well as various organic forms. Advances in modern analytical techniques have identified over 300 species of naturally occurring organoarsenicals. Unfortunately, the toxicity of many of these compounds remains unassessed.
Since it is widely understood that inorganic arsenic species are generally more toxic than organoarsenicals, regulators have begun setting limits for inorganic arsenic in food. Although organoarsenicals have not shown acute toxicity, their potential toxicity may arise from metabolic transformations leading to toxic metabolites. To clarify these concerns, the European Commission has requested a risk assessment on organoarsenic species in food from the European Food Safety Authority (EFSA). EFSA has now presented its scientific opinion on the risk assessment of small organoarsenic species (see the news below).
In its assessment, EFSA not only investigated the risks associated with small organic arsenic species but also highlighted gaps in the available information on the presence and toxicity of organoarsenicals in food. The scientific community is called upon to help address these open questions.

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.
Health risk assessment of small organoarsenic species in food
The European Commission has asked the European Food Safety Authority (EFSA) for a risk assessment on organoarsenic species in food. EFSA has now presented its scientific opinion on the risk assessment on small organoarsenic species.
