Welcome to the October issue of EVISA's Speciation Newsletter !
Certified Reference Materials (CRMs) are valuable tools for the quality assurance in analytical chemistry. Mercury is a global pollutant and classified by the World Health Organization as a major public health concern. Human biomonitoring is requested in order to evaluate actual exposure to the toxin. Considering the demands of human biomonitoring of hair for mercury and
other elements, an international group of researchers developed a CRM for mercury speciation analysis with extended
certification to cover some elements with toxicological and nutritional
significance (see the news below).
Arsenic is a naturally occurring element in the environment that can enter the food supply through soil, water or air. While cereals made from wheat and other grains sometimes contain arsenic, rice
cereals can be especially high because rice absorbs up to 10 times more
of the heavy metal from the soil than other grains do. The U.S. Food and Drug Administration (FDA) has recently approved its guidance level on inorganic arsenic in rice cereals for infants. The FDA has concluded that good
manufacturing practices can reliably produce rice cereals with no more
than 100 µg/kg (ppb) inorganic arsenic (see the news below).
Organotin compounds (OTCs) represent an essential class of
organometallics in modern life. Due to their versatile characteristics,
OTCs have been widely used in industry and agriculture since the 1950s,
with an annual production surpassing 50 000 tons in the late 90's. Unfortunately, it was recognized only lately that some of those
chemicals have the ability to mimic or antagonize the action of
hormones, thus affecting the normal functioning of organisms leading to
deleterious effects. A group of researchers from the University of Münster developed a new
approach for speciation analysis of organotins based on a mild size
exclusion chromatographic (SEC) separation coupled to inductively coupled
plasma mass spectrometry (ICP-MS) and native electrospray ionization
mass spectrometry (ESI-MS). Using these complementary techniques, even
weak interactions of OTCs with model proteins were investigated (see the news below).
