Welcome to the November issue of EVISA's Speciation Newsletter!
Mercury and selenium have some interesting relation. While selenium is an essential trace element, mercury has no beneficial function for life. The toxicity of mercury is dependent on its species being present that influences its transport, distribution and target organ. A group of German researchers now studied the transport and distribution patterns of different mercury species in the fruit fly as a model organism (see the news below).
Selenium can act as an antagonist reducing the toxicity of mercury. Anyhow, as an essential trace element selenium is required for sustaining life. At present, 25 selenoproteins, containing selenocysteine residues at their active sites, are known in humans with roles as antioxidants, in selenium transport, in maintaining intracellular redox status and in thyroid hormone production, amongst other functions.
However, selenium is not only essential for humans but for animals and plants as well. According to a new theory, the essentiality of selenium
was even a limiting factor for life during the history of the earth and a factor for mass extinctions (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.
New theory for the cause of Earth's mass extinctions: lack of essential selenium
A new theory suggests most of Earth’s mass extinction events could have been caused by a lack of essential trace elements in the world’s oceans, causing fatal deficiencies in marine animals, from plankton to reptiles.

Uptake of mercury species by fruit flies
Researchers from the Universities of Münster and Potsdam developed a method for the quantitative bioimaging of mercury in fruit flies for investigating the uptake of different mercury species.
