Welcome to the September issue of EVISA's Speciation Newsletter !
Chromium is
a controversial element with important biological characteristics, depending on
its different species. While chromium is considered beneficial in its trivalent
form, the hexavalent species is classified as genotoxic and carcinogenic. For this reason, there is a need to detect hexavalent chromium in order to avoid health risks. A group of Czech researchers now proposes a novel LC-ICP-MS based approach
for the accurate and precise chromium speciation in biological tissues (see the news below). Hexavalent chromium is also a strong oxidising agent, that hardly can survive for extended periods in presence of organic materials. Not surprisingly, Cr(VI) was not found in any of the biological materials (see the news below).
Copper is an essential element as a cofactor for more than twenty metalloproteins. The blood is the medium for its transport and distribution. For a full understanding of the copper homeostasis, the speciation of copper in blood has to be known. A group of Nordic researchers investigated the Cu(II) binding to different proteins in human blood (see the news below).
Rice grown on contaminated soil is a health risks in many parts of the world. Because of the growing conditions on paddy soil, the rice plant picks up more arsenic than any other cereal. A group of researchers from the UK and Iraq report on studies on the
arsenic uptake by rice plant grown within a high arsenic-containing
environment down to the cellular (DNA) level. They claim to have
detected arsenic associated with, or integrated within, the DNA
fractions (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 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.
Arsenic speciation in different parts of the rice plant
A group of researchers from the UK and Iraq report on studies on the arsenic uptake by rice plant grown within a high arsenic-containing environment down to the cellular (DNA) level. They claim to have detected arsenic associated with, or integrated within, the DNA fractions.

Copper(II)-binding equilibrium in human blood
A group of Nordic researchers investigated the Cu(II) binding to different proteins in human blood.

Chromium speciation in biological tissues
A group of Czech researchers proposes a novel LC-ICP-MS based approach for the accurate and precise chromium speciation in biological tissues. Obtained results indicated that the majority of chromium is bound to the solid residue obtained by leaching the tissue. Cr(VI) was determined in none of the samples investigated.
