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

According to the IUPAC Definition for speciation analysis, isotope ratio analysis is part of it. Anyhow, isotope ratio measurements have found new applications beyond Geochemistry, widening the scope and the group of researchers involved. Multi-collector ICP-MS has dislodged Thermal Ionization Mass Spectrometry (TIMS) in many of these applications. Currently, the researchers had the choice between only two instruments, one of which the Thermo Neptune is on the market since more than 20 years. Thermo now has launched a new system incorporating new software and hardware technology (see the news below).

As has been mentioned in our December Newsletter, Mercury is a toxic heavy metal being in the focus of EVISA's Speciation Newsletter nearly permanently. Its bioavailability, bioaccumulation and toxicity is heavily depending on the species being present. The main exposure route for humans is the consumption of fish.  A Chinese group of researchers now investigated the mercury-binding proteins in tuna and salmon. More than half of the mercury from fish muscle was found in the soluble protein fraction. Beta-actin was identified to bind more than 30% of the total Hg in tuna muscle (see the news below).

Seafood is also the main source for arsenic exposure. Again, the toxicity of arsenic depends on its speciation, spanning a range from non-toxic (Arsenobetaine) to carcinogenic (inorganic arsenic). For a meaningful risk assessment, the arsenic content of seafood therefore calls for speciation analysis. A Chinese group of researchers now have developed an analytical method for arsenic species that can be used for various seafoods such as seaweed, fish, shellfish and shrimp (see the news below).

Normally, researchers working in the field of speciation analysis would meet during this month at the "European Winter Conference on Plasma Spectrochemistry (EWCPS) ". However, as most conference in these difficult times the EWCPS has been postponed (see the Agenda of Events).

While the availability of the first vaccines gives some hope to overcome the COVID-19 pandemic, the vaccination of the human population is a formidable task that certainly will take longer than only a few months. We will therefore probably exchange our research results only in virtual meetings during the first half of this year. We will keep you informed about the organization of relevant events.

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.

A universal method for the speciation analysis of arsenic in various seafoods
A Chinese group of researchers have developed an analytical method for arsenic species that can be used for various seafoods such as seaweed, fish, shellfish and shrimp. Using microwave-assisted extraction, the extraction efficiency was better than 95% for all sample types without altering their original speciation.

Mercury-binding proteins in tuna and salmon
A Chinese group of researchers investigated the mercury-binding proteins in tuna and salmon. More than half of the mercury from fish muscle was found in the soluble protein fraction. Beta-actin was identified to bind more than 30% of the total Hg in tuna muscle.

New isotope ratio mass spectrometry system delivers high-precision analysis for a range of applications
A new inductively coupled plasma mass spectrometry (ICP-MS) instrument has been designed to enable scientists working in earth sciences, nuclear safeguards, and biomedical research to conduct reliable, high-precision isotope ratio analysis across a wide range of applications without compromising sensitivity, stability, or ease-of-use

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.
