Dear Subscriber !

Welcome to the April issue of EVISA's Speciation Newsletter.

Tributyltin (TBT) is a endocrine disruptor mainly known for its toxic effect on mollusks called "imposex". Because of this toxic effect, the use of TBT in antifouling paints has been banned. The question is, what is the risk related to the consumption of seafood contaminated with TBT. In a  study from the University of California, Irvine, it is shown that
prenatal exposure to the pesticide increased obesity in mice for several generations by permanently changing how fat cells develop, mature and store fat. An alarming result! (see the news below)

We often reported about the health risk resulting from the methylmercury concentration in some seafood.
There is currently only a recommendation from the European Commission to breastfeeding and pregnant women and children to limit their consumption of big predatory fish such as tuna and swordfish. However, no maximum limits have been set up yet.  The European Commission needed a validated method to eventually introduce maximum limits for methylmercury in the legislation and ensure enforcement of the regulated limits in Member States. As a reaction JRC's European Union Reference Laboratory for Heavy Metals in Feed and Food has now validated a simple analytical method for the determination of methylmercury in seafood. The validated method can be used by any laboratory that do not run many methylmercury analyses per year and which do not have sophisticated techniques at their disposal (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.

JRC validates simple method to monitor methylmercury in fish
JRC's European Union Reference Laboratory for Heavy Metals in Feed and Food validates a simple analytical method for the determination of methylmercury in seafood.

Tributyltin exposure promotes obesity in following mice generations
Prenatal exposure to the pesticide tributyltin increased obesity in mice for several generations by permanently changing how fat cells develop, mature and store fat, according to a new study. The children, grandchildren and great-grandchildren of pregnant mice exposed to the chemical in their diet had bigger fat cells, more fat deposits and the start of liver disease.

Mercury isotope fractionation provides new tool to trace the source of human exposure
Using the presence of mercury in urine as a test to determine mercury exposure from dental amalgam fillings may significantly overestimate the amount of the toxic metal released from fillings, according to University of Michigan researchers.
