Dear Subscriber !
Welcome to the November issue of EVISA's Speciation Newsletter.
Already last month we mentioned the special value of the enhanced information provided by speciation analysis for life sciences. The role of metallic species in life science is the target of a new and fast growing science called "metallomics". Biological functions of metals are not only specified by the element itself, but also by its chemical form and by its organ, cell and subcellular location. For this reason imaging analysis plays a growing role especially in life science. A group of researchers from the University of Münster now has demonstrated a new technique for imaging mass spectrometry based on laser ablation sampling and atmospheric plasma post-ionization. By using two different sources in parallel, both molecular and elemental information can be obtained, providing both means for structure elucidation and quantification. While the capabilities of this new technique have to be investigated thoroughly, first results in the direction of spatially resolved speciation analysis are promising (see the news below).
Speciation analysis is also very important for food and nutrition science. Because of the very different level of toxicity of different arsenic species, meaningful risk assessment for arsenic in food requires data on the arsenic speciation. A new study now provides such data for infant foods based on rice cereals (see the news below).
An important part of mercury brought to the environment by humans is the result of its use for the extraction of gold and silver in mining activities. A new study now shows, that pollution is ongoing, even that the mining activity has been finished more than 100 years ago (see the news below).

NEWS

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.
Arsenic Speciation in Rice Cereals for Infants
A new study from the US determined levels of different arsenic species in infant cereals that present a potential health risk to the infant population. While total As concentrations as high as 272 µg/kg were observed, the Chinese maximum allowed concentration of 150 µg/kg inorganic As in rice was slightly surpassed by only one American rice cereal.

Spatially resolved speciation analysis: A new technique based on laser ablation with simultaneous elemental and molecular mass spectrometry
Researchers from the University of Münster (Germany) now demonstrated the first simultaneous elemental and molecular MS imaging approach based on laser ablation sampling for spatially resolved speciation analysis. The dual hyphenated system combines the advantages of LA-ICP-MS such as low detection limits and high spatial resolution with information on the chemical identity and therefore can be used not only for localization of metals, but also for identification of metal species in biological samples.

Toxic mercury remnants of gold rush will seep into San Francisco area waterways for millennia
California’s gold rush ended more than a century ago, but mercury used to mine the gold is still making its way into valleys below the mines and the contamination will probably last thousands of years, a new analysis shows.
