Simultaneous preconcentration of copper, nickel, cobalt and lead ions prior to their flame atomic absorption spectrometric determination
Date: May 1, 2007
Author:
A sensitive and simple method for the simultaneous preconcentration of nutritionally important minerals in real samples is based on the adsorption of metal dications on 4-propyl-2-thiouracil loaded on activated carbon.

Reactivity of ashes from biomass combustion plant in biomass combusting atmospheres
Date: Apr 20, 2007
Author:
Exposure tests were carried out to study the reactivity of filter and cyclone ashes from a biomass combustion plant. The changes of C-, Cl- and S-content of the exposed ashes were analyzed by inductively coupled plasma atomic absorption spectroscopy.

Organic atomic kiwi
Date: Apr 15, 2007
Author: David Bradley
Could the claims of the so-called "organic" farming movement be true after all? Analysis of the antioxidant, mineral, and nitrate composition of kiwifruit would suggest so. A comprehensive study of the constituents of organically grown kiwifruit reveal that organically grown kiwifruit contain more health-promoting factors than those grown using conventional methods.

Pigment problem solved with cotton bud
Date: Jan 15, 2007
Author: David Bradley
Canadian researchers have used atomic absorption and mass spectrometry to investigate the various pigments in two cultural objects, a painting and a map. Their findings reveal the nature of the inorganic pigments and provide clues as to why these objects are darkening with time. Such results could assist in their conservation.

Bioaccumulation of metals in the common carp exposed to cadmium, mercury and lead
Date: Jan 10, 2007
Author:
The concentrations of mercury, cadmium and lead at various exposure periods were determined in the gill, kidney, liver and muscle of the common carp using the hyphenated technique of size-exclusion chromatography (SEC) and inductively coupled plasma mass spectrometry (ICP-MS).

Polonium testing
Date: Dec 15, 2006
Author: David Bradley
Polonium unwittingly became element of the year in 2006, now researchers in Italy have devised a new simpler method for the determination of the highly toxic polonium-210 isotope as well as lead-210 in rock and soil samples.
