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

Selenium is an essential element involved in many physiological processes. However, it is often called the "essential poison", because too high concentrations are also toxic for the organism. The problem with selenium is that the range of beneficial concentrations is rather limited to about one decade. Even further, toxicity depends on the speciation or in other words on the chemical form of the selenium present.  Canadian researchers now found a special selenium species in the red blood cells of Inuit living in Nunavik (Canada). They also found that the origin of this compound is a special food made from the skin of beluga (see the news below). Whether this compound is acting as an effective antidote against methylmercury also present in the food has to be investigated.

Titanium dioxide is a compound used as a whitener (E171) in some foods (such as chewing gum). Interestingly it is often used in the form of nanoparticles. As a reaction on reports of precancerous colorectal lesions resulting from chronic exposure of rats to E171, France government has decided to ban its use as a food additive (see the news below).

Arsenic is often used as a synonym for poison. Researchers from Florida International University Herbert Wertheim College of Medicine are part of an international team that has discovered a new broad-spectrum antibiotic that contains arsenic. The antibiotic, arsinothricin or AST, is a natural product made by soil bacteria and is effective against many types of bacteria (see the news below).

Gadolinium, in the form of special complexes is used as contrast agent for magnetic resonance imaging as a diagnostic tool in medicine. Since researchers have found that small quantities of Gadolinium are retained in the human body for long time periods, Radiologists are requested to use these compounds only when really necessary. The U.K. Royal College of Radiologists (RCR) has now updated its guidance on the administration of gadolinium-based contrast agents (GBCAs) to adult patients (see the news below).

Questions related to the biological function and metabolism of metal species will be discussed during the 7th International Symposium on Metallomics, taking place June 30 to July 3rd in  Warsaw (Poland).  


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.

Selenoneine is a major selenium species in red blood cells of Inuit from Nunavik
Canadian researchers found selenoneine as the major selenium species in red blood cells of Inuit from Nunavik as a result of their dietary habits.

U.K. issues new advice on the use of gadolinium-based contrast agents
The U.K. Royal College of Radiologists (RCR) has updated its guidance on the administration of gadolinium-based contrast agents (GBCAs) to adult patients. The 23-page document addresses concerns about possible long-term gadolinium retention in the brain and the risk of nephrogenic systemic fibrosis.

Scientists discover new broad-spectrum antibiotic based on arsenic
Researchers from Florida International University Herbert Wertheim College of Medicine are part of an international team that has discovered a new broad-spectrum antibiotic that contains arsenic. The study, published in Nature’s Communication Biology, is a collaboration between Barry P. Rosen, Masafumi Yoshinaga, Venkadesh Sarkarai Nadar and others from the Department of Cellular Biology and Pharmacology, and Satoru Ishikawa and Masato Kuramata from the Institute for Agro-Environmental Sciences, NARO in Japan.

France to ban titanium dioxide whitener in food from 2020
France will ban the use of titanium dioxide as a food additive from 2020 after the country’s health and safety agency said there was not enough evidence to guarantee the safety of the substance.
