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

Different toxicity for the different species of an element is one of the main motivation for doing speciation analysis.  The difference can result from differences in uptake because of different bioavailability, differences in the distribution within the organism or different activity on the target organ.

Methylmercury has not only higher toxicity in comparison to inorganic mercury, also the different target organs. Methylmercury can cross the blood-brain-barrier and therefore shows important neurotoxicity. Humans are mainly exposed to methylmercury via seafood. An intensive research is focusing on the processes involved in the transformation of mercury  to methylmercury and its introduction to the marine food web. A new study now has identified bacterial activities in arctic ice as a new source (see the news below).

Another question for investigating health risks is the metabolic transformation of species once they are taken up. Researchers now have investigated the metabolism of inorganic arsenic and have identified two
new methyldithioarsenicals (see the news below).

Whether the metabolites are more or less toxic than the species taken up is another question of concern for studying toxicity. In order to elucidate the metabolism of selenium,
five low molecular weight species of selenium were investigated regarding their toxicological effects, cellular bioavailability and species-specific metabolism in human cells (see the news below).


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.

Toxicity and bioavailability of different selenium metabolites
To further elucidate the metabolism of Se, five low molecular weight species of selenium were investigated regarding their toxicological effects, cellular bioavailability and species-specific metabolism in human cells.

Researchers found new sulfur-containing metabolites in the urine of rats exposed to arsenite
An international research team led by X. Chris Le from the University of Alberta has identified methylated dithioarsenicals in the urine of rats fed with sodium arsenite.

New study identifies source of methylmercury in Southern Ocean sea ice
Methylmercury, a potent neurotoxin has been found in sea ice in the Southern Ocean, according to new research. This latest study demonstrates how sea ice bacteria can change mercury into its more hazardous form, contaminating marine life and birds.

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.
