Aquatic aluminium all-clear
Date: May 15, 2010
Author: David Bradley
Inductively coupled plasma atomic emission spectroscopy was used to track the path of an aluminium contaminant in water as it travels through the food chain. The study indicates that the toxic metal accumulates only in the inedible parts of shellfish.

Heavy metals and hardened arteries
Date: Apr 15, 2010
Author: David Bradley
The way in which arterial plaques form, atherogenesis, is not yet completely understood despite a significant number of research studies in this area. Now, a study using rabbits on a high-fat diet (HFD) has investigated the effects of changes in the concentrations of trace elements., iron (Fe), copper (Cu) and zinc (Zn), in several tissues using atomic absorption spectroscopy.

Dual-column capillary microextraction combined with ETV-ICP-MS for the speciation of arsenic in human hair extracts
Date: Mar 1, 2010
Author:
A dual-column capillary microextraction was developed for the sequential separation/preconcentration of arsenite, arsenate, monomethylarsonic acid and dimethylarsinic acid in extracts of human hair followed by electrothermal vaporization inductively coupled plasma mass spectrometry detection with iridium as permanent modifier.

Date: Feb 15, 2010
Author: David Bradley
Flame atomic absorption spectrometry (FAAS) can be used effectively as an alternative method for the determination of calcium and magnesium ions in biodiesel and fuels derived from vegetable oil, according to researchers in Brazil. The technique precludes certain preparative steps and avoids the need for some toxic organic solvents.

Date: Feb 1, 2010
Author:
Whole blood manganese was measured in eighteen dogs with congenital portosystemic shunts, 26 dogs with nonhepatic illnesses, and 14 healthy dogs by graphite furnace atomic absorption spectrometry.
