Welcome to the June issue of EVISA's Speciation Newsletter !
This month we are discussing speciation analysis for elements that have not been addressed very often. Gadolinium-based contrast agents (GBCAs) are used since their
introduction in the 1980s for improving the contrast in magnetic
resonance imaging for medical diagnostics. While considered to be safe for nearly 25 years, in the last decade it
has become well established that a trace amount of Gd does accumulate
for a prolonged time in multiple organs, including the brain, after
single and even more so after repeated GBCAs administration.
A group of French researchers developed a method for enhancing the poor
extraction of retained gadolinium from brain tissue. Subsequent analysis
using size exclusion chromatography–inductively coupled plasma–mass
spectrometry (SEC-ICP-MS) was intended to shed the light on the
speciation of the additionally recovered Gd (see the news below).
Technetium-99 (99Tc) is a man-made species mainly generated by the thermal neutron fission of 235U and 239Pu and is released to the environment from spent fuel reprocessing plants and nuclear weapon tests. The toxicity, bioavailability, and mobility of 99Tc is seriously dependent on its chemical forms in the environment. A group of Chinese researchers developed a method for the speciation of
rhenium using the hyphenated technique of capillary
electrophoresis-inductively coupled plasma mass spectrometry. Since the
rhenium species are known as the analogues of technetium, the proposed
method retains the great potential for the speciation analysis of 99Tc
in various samples (see the news below).
During recent years increasing amounts of Technology Critical Elements
(TCE) are being released to the environment as a result of the growing
use of electronic and industrial products. One of the Less Studied Technology Critical Elements (LSTCE) is
tellurium (Te), which is increasingly used in rewritable CDs and DVDs,
solar panels, and in semiconductor applications but has also been used
to vulcanize rubber or to tint glass and ceramics. Although the chemical
properties of Te are well known information about its chemical behavior
in natural systems is limited. Polish researchers now developed, optimized and validated a method for the
determination of inorganic ionic Te(VI) and Te(IV) forms in
easily-leached fractions of soil by Ion Chromatography-Inductively
Coupled Plasma-Mass Spectrometry (IC-ICP-MS) (see the news below).
Due to the ongoing COVID-19 pandemic, many of the conferences scheduled for before September have been postponed or modified to virtual events. EVISA's Agenda of Events is frequently updated in order to keep you informed about the organization of relevant events.
