Welcome to the August issue of EVISA's Speciation Newsletter!
The assessment of human health risks is a major driving force to do speciation analysis, since toxicity depends on compounds rather than elements. This is especially true for arsenic species that span a toxicity range from non-toxic (Arsenobetaine) to carcinogenic (inorganic arsenic). For this reason, different legislative bodies are discussing the necessity to have arsenic speciation information for some foodstuffs (rice, algae, etc.). ISDO/DIN is preparing a standard method to comply with such upcoming regulation (see the news below).
Inorganic arsenic in rice is a health hazards for millions of people especially in south and southeast Asia. Researchers from UK have now optimized the cooking of rice in order to get rid of most of inorganic
arsenic (see the news below).
While gadolinium is quite toxic, more than 1 million patients per year receive an intravascular injection of up to 1 gram gadolinium-based contrast agents (GBCAs) for improving diagnostic image quality. Despite the toxicity of gadolinium, GBCAs are considered safe, since gadolinium is masked within a stable chelate-compound and normally excreted from patients body within few hours. However a recent study has found that some GBCAs are staying in the brain for much longer time. FDA is now evaluating whether such retention comes with health effects (see the news below).
Selenium is an essential trace element and people with deficiency may adjust their daily uptake with food supplements. Polish researchers now found out that labeling of such food supplements is often incorrect with respect to selenium concentration (see the news below).
The role of metal(loid) species in life sciences will be discussed at the next Metallomics Conference that will take place in Beijing in September 9-12 2015. EVISA members will be present and report about the event.

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 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.
FDA investigating risk of gadolinium contrast agent brain deposits
The Food and Drug Administration is investigating the risk of brain deposits after recurring use of gadolinium-based contrast agents for MRI, the agency announced in a statement.

Call for help: ISO/DIN Project: Standard method for arsenic speciation analysis using HPLC-ICP-MS
Currently, ISO is working on a standard method for the determination of arsenic species (As(III), As(VB), MMA, DMA) by HPLC-ICP-MS. German DIN working groups look for help to support this project.
